This indicator is especially useful, when estimating the progress of the imidization reaction or to compare different sets of samples in a real-life application. Therefore, the aim was to introduce a similar figure for the proposed LIBS method. As the hydrogen emission and the C2 swan band show a trend during the imidization reaction whereat the hydrogen signal gradually decreases while the C2 signal steadily increases, both signals are basically suitable for monitoring the reaction progress. In order to resolve the reaction trend as accurately as possible, the ratio of the C2 intensity to the H emission signal was introduced. Analogous to the formula of the imidization degree based on IR spectroscopy, reference samples are also necessary for the calculation using LIBS emission signals. Because the two LIBS bands (C2 and H) occur in non-imidized samples as well, the stated formula based on IR spectroscopy (Eq. 1) had to be adapted.

Exposure at 300°C or 400°C led to nearly constant conversion rates, while the maximum amid acid to imide conversion was obtained while curing at 400°C with imidization degrees from 97 to 107% and RSD from 5.1 to 13.6% (average for all samples cured at 400°C and various curing times, n = 24).Fig. 7Degree of imidization for self-synthesized polyimides subjected to varying curing temperatures and times based on LIBS measurements (n = 4)\", \"title\": \"LIBS as a novel tool for the determination of the imidization degree of polyimides\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "e22cd2b1a50afdc52c95072e1db2510bf3ee74a976789c4bbdbe7f4e537ac9c2"}

Especially when considering the mapping and depth profiling abilities, LIBS could become a vital tool to ensure constant material properties. One highly interesting application area could be the investigation of films and coatings because they require homogeneous attributes throughout the entire thickness. As the calculation of a quantitative measure like the imidization degree is extremely helpful for industry applications, a comparison of calculated imidization degrees based on IR spectroscopy as well as LIBS measurements is displayed in Fig. 8. With the red line marking exactly the same results for both methods, it is shown that both techniques yield very similar outputs up to an imidization degree of 50%. Beyond that, LIBS tends to provide lower results compared to IR spectroscopy, but the course of the trend is depicted for both measurement protocols. Considering the error, IR has a relative standard deviation of 6% on average for all polymer films and imidization degrees, with the error decreasing at higher imidization degrees (8% at 160 °C, 2% at 400 °C). In contrast, the average relative standard deviation for LIBS is 8% across all samples and curing conditions. However, the error increases with increasing imidization (5% at 160 °C, 10% at 400 °C). Differences in imidization degree and precision can be expected due to the different cross-sections of the two methods. First of all, the ATR-IR penetration depth is approximately 1.3 µm at 1500 cm−1 and changes with wavenumber, while the LIBS ablation depth is around 1 µm. In addition, the active sampling area for ATR-IR spectroscopy is about 0.5 mm2 representing the size of the ATR crystal of the used instrument, and all 6 scans were measured and averaged from that same spot. Thus, the outcome reflects only deviations resulting from sample measurement and between samples but not variations in sample homogeneity. For LIBS, on the contrary, an area of 2.4 mm2 was sampled using 3 parallel line scans, meaning that the sample was scanned along its entire width and variations in reaction rate due to sample preparation were included in the signal.Fig. 8Comparison of IR- and LIBS-based imidization degrees\", \"title\": \"LIBS as a novel tool for the determination of the imidization degree of polyimides\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "23f2b925f4293da544bacc3e17b1da861fe5b4abcb80a102125e5df88c2c16d7"}

It was possible to track the reaction using the C2 emission band as well as the H signal. IR spectroscopy served as a reference during method development and provided a template to implement a simple formula to calculate the imidization degree based on the LIBS signal trends of C2 and H. A non-cured as well as a maximum cured polyimide sample had to be used for scaling since the two LIBS bands also occur in non-imidized samples as well. Using the novel formula, the calculation of imidization degrees obtained using LIBS was possible, and the outcome was in good accordance with IR results. Observed differences could be attributed to different cross-sections of the two methods, regarding penetration depth and sampling area. Using LIBS, an area almost 5 times larger than with IR spectroscopy was analyzed, which meant that local variations due to sample preparation and reaction rate were included in the signal. In addition, the calculation of the imidization degree is based on the ratio of two vibrational lines using IR spectroscopy, providing information about changes in the molecular structure, while the formula based on LIBS uses the ratio of C2 and H emission signals, indicating alterations in the elemental composition. Therefore, degrees of imidization from two different analysis methods cannot provide exactly the same numerical value, but a relative comparison within a sample set using IR or LIBS based results is possible. Nevertheless, method improvements using additional spectral information in the form of elemental or molecular bands, the selection of alternative standards as reference values, etc. would be possible.

The formation of the imide bond in the course of the reaction is confirmed by the occurrence of the C = O stretch (imide I) at 1770–1780 cm−1 and 1720–1740 cm−1, the C-N stretch (imide II) at 1360–1380 cm−1, and the C-H bend (imide III) and C = O bend (imide IV) in the ranges of 1070–1140 cm−1 and 720–740 cm−1.

One huge advantage of LIBS is its depth profiling capability. This could be especially useful, when a layer construction is under observation or if the defective area is not at the sample surface during failure analysis. To assess the applicability of the aforementioned LIBS method for layered structures, a stacked model sample was prepared from PAA solution. A first layer of precursor (50 µl) was thermally treated at 400°C for 5 min. Subsequently another layer of precursor (20 µl) was added on top and dried at 80°C for 120 min, according to Fig. 9a. Depth profiling was done starting from the top layer dried at 80°C down to the bottom layer cured at 400°C. A total number of 16 layers, each representing 1 µm in ablation depth, were ablated, and the average of every layer was calculated for data evaluation. The same samples used for the LIBS method development served as reference to calculate the imidization degree: PAA-080–120-1 to 10 were used to obtain C2,min and Hmin, while PI-400–120-1 to 4 were analyzed for C2,max and Hmax according to Eq. 2. Figure 9b shows the LIBS imidization degree for the layered samples, indicating an increase of the imidization degree after 4 µm. The trend of the depth profile and the calculated imidization degree rising from 0 to 100% corresponds well with the sample structure, as we can assume that the top layer was hardly or not imidized at all, while the bottom layer was completely imidized. Additionally, it has to be kept in mind that the course of the curve in the transition region is dependent on intermixing or solving effects when applying the top layer in the form of the PAA precursor dissolved in NMP as well as the generated crater shapes derived from a Gaussian laser beam profile.Fig. 9Schematic of the model sample prepared for depth profiling (a) and LIBS imidization degree showing the increase of the imidization degree with depth (b)\", \"title\": \"LIBS as a novel tool for the determination of the imidization degree of polyimides\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "04b7f9e80056e3f0caaeb9d58ba5e45da2994b3865c82c02b2d889ec789c3f77"}

Self-synthesized polyimides were used as reference material according to Eqs. 1 and 2 to ensure the versatility of the implemented method. This could be especially useful in cases where there is no matching raw material available for example during failure analysis. The two commercial polyimide films used for testing were a general-purpose polyimide film (PI1) used for applications in fiber optics cables, insulation tubings, or as diaphragm sensors and manifolds in the automotive industry and another polyimide (PI2) based on a photosensitive precursor common in the electronics industry [29]. Both films were first analyzed using IR spectroscopy. The ATR-IR spectra of both samples and the bands used for determining the imidization degree are displayed in Fig. 10a. It can be seen that the spectra of both polyimides differ; especially for PI2, this is troublesome as the band of the aromatic ring stretching (C = C) around 1500 cm−1 is normally used as reference and the determination of the peak area is affected. For that reason, determining the imidization degree using the traditional IR approach works for PI1 but leads to an unnaturally high imidization degree for PI2, as can be seen in Fig. 10b.

The synthesis of PI-coated cathode materials is the focus of this section, and the coating process is shown in Fig. 2a. Herein, the thermal imine method is used to realize the coating.

As the cathode active storage materials, the lithium-ion storage mechanism is depending on the reversible reduction reactions of carbonyls in PI repeat units. This reaction mainly takes place at 1.5 ~ 3.5 V. Presently, the most widely used dianhydrides are pyromellitic dianhydrides (PMDA), naphthalene-tetracarboxylic dianhydrides (NTCDA), and perylene-tetracarboxylic dianhydrides (PTCDA). Much effort has been devoted to exploring the relationship between PI structure and electrochemical performances. Hernández et al. [107] synthesized many different PI active storage materials by the polycondensations of PMDA, NTCDA, and 4,4’-(hexafluoroisopropylidene)diphthalic anhydride (6FDA) with various diamines shown in Fig. 10a. They utilized these PI active storage materials to assemble LIBs, whose structure is schematically shown in Fig. 10b. As NTCDA-PIs possess good conjugation structure, it shows better cycling performance and rate capability than PMDA-PIs and 6FDA-PIs. Then, NTCDA was used as the main dianhydride to synthesize a series of PI active storage materials, whose rate capability performances are shown in Fig. 10c. Firstly, NTCDA was polymerized with different aromatic diamines such as 3,3-bis-(4-aminophenyl)phthalide (APh), 3,3-bis-(4-aminophenyl)phthalimidine (APhl), 9,9-Bis-(4-aminophenyl)anthrone (AAn), and 3,3-bis(4-aminophenyl)quinuclidine) (AQn-LFSI), where NTCDA-APh PIs exhibit the best rate capability (146 mAh g−1 at 25 mA g−1, 100% of its theoretical capacity), as it took place the three-electron reaction where two electrons were from the imide part and the additional one from the extra carbonyl group of diamine. NTCDA-AAn PIs only take place the two-electron reactions (96 mAh g−1 at 25 mA g−1, 73% of its theoretical capacity) as the extra carbonyl group was not redox-active. Similarly, NTCDA-APhl PIs also take place the two-electron reactions (107 mAh g−1 at 25 mA g−1, 73% of its theoretical capacity) as the extra amide moiety was not redox-active. Additionally, when the ionic group is introduced in the structure of PIs as NTDA-AQn-TFSI, it can deliver the specific capacity of 90 mAh g−1, suggesting that the ionic moiety is not able to improve the rate capability of the polymer. They also investigated PIs synthesized with different aliphatic diamines including 4,7,10-trioxa-1,13-tridecanediamine (TOTDA), 4,9-dioxa-1,12-dodecanediamine (DODDA), and 1,12-dodecanediamine (DDA) and found that the NTCDA-DODDA PIs and NTCDA-TOTDA PIs exhibit better rate capability than NTCDA-DDA PIs due to the presence of oxyethylene fragments which is known to solvate lithium ions and improve the ionic conductivity. Therefore, the conjugation structure, redox-active carbonyl group, and oxyethylene fragments are three kinds of important structural units to tune the electrochemical performance.Fig. 10a Polycyclocondensation reaction mechanism and chemical structures of starting monomers. b Schematic of LIB assembled with polyimide cathode. c Rate capability performance\", \"title\": \"Polyimides as Promising Materials for Lithium-Ion Batteries: A Review\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "3f7e75b1fc47fae6a6133340fa0df00420b49df36eef65440dafedd9363607cc"}

Currently, increasing the specific capacity and operating voltage are two effective strategies to increase energy density. Nevertheless, the average operating voltage is limited by the intrinsic structures of PI molecules, which are less than 3.5 V usually. Designing structures that can withstand high voltage is challenging. Therefore, increasing the specific capacity is the first choice.

However, there are still some problems in the practical application of PI active storage materials including the low utilization rate of redox-active carbonyl groups and poor electronic conductivity. To solve these problems, the following two strategies are adopted. Firstly, the reasonable structure design of PI active storage materials should be promoted. The energy storage mechanism of active storage materials is closely related to the conjugated structures and redox-active sites. Utilizing the large π–π packing structures is encouraged, and more redox-active functional groups should be introduced such as the disulfide bond (S–S), azo bond (N = N), and imine bond (C = N) besides carbonyl groups (C = O). Furthermore, ordered structures such as popular covalent organic framework compounds (COFs) linked by imine units should be considered. Secondly, more advancing electron-conducting materials should be investigated and introduced to the PI active storage materials to enhance the energy utilization rate of PIs.

To date, the preparation methods for PI separators are still confined to the laboratory, including template, phase separation, and electrospinning methods. Figure 3a shows a schematic of the template method reported by Lin et al. [43]. Typically, the template method employs inorganic salts as templates to make pores. In their work, LiBr and SiO2 were mixed into a PAA solution and doctor blade to produce the membrane. Then, the PAA membrane was thermally imidized to convert it into a PI membrane. Finally, a nanoporous PI membrane was obtained by washing LiBr away with water. The main advantage of this method is that it maintains the intact pore structure. Moreover, the added SiO2 enhances electrolyte wettability even further and provides good thermal stability and mechanical properties to the separator, which could widen the service temperature and prohibit Li dendrites effectively. Li et al. [44] reported the phase separation method to fabricate PI separators. As shown schematically in Fig. 3b, dibutyl-phthalate and glycerin are added to the PAA solution, which is then blade onto a glass plate to obtain the PAA membrane. This PAA membrane is further immersed in an ethanol coagulation bath at 40 °C several times to remove the solvent and additives for making holes. Finally, the same method of thermal imidization is adopted to convert the PAA membrane into a PI membrane. The cell assembled with this PI separator exhibited good electrochemical performances at 140 °C, whereas the cell with a PE separator failed. The reason for the good performance of the cell at high temperatures is attributed to the PI separator maintaining good thermal stability without observable shrinkage at high temperatures. Similarly, PI separators prepared by the modified method have been further explored by Song and Zhou et al. [45, 46] to boost the safety of LIBs. Compared with the above methods, the electrospinning method is simpler and more versatile for membrane preparation. Electrospinning is one of the most promising methods to realize PI separator commercialization. Li et al. [47] employed the solution blow spinning for fabricating PI separators. The technique includes three steps: ①synthesizing PAA, ② electrospinning, and ③ thermal imidization. The preparation process is shown in Fig. 3c. As the PI separator made by the electrospinning method possesses a conductive pore structure, it further enhances the ionic conductivity. While the size of the hole is large, the formed Li dendrites easily penetrate the separator and lead to the ISCs. Therefore, many references have reported the modified electrospinning PI separators.Fig. 3Different preparation methods for PI separators. a Template method. b Phase separation method. c Electrospinning method\", \"title\": \"Polyimides as Promising Materials for Lithium-Ion Batteries: A Review\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "dda6bb8456c478973e65151524b110f48a0d65a06512e21562a214909cf4f0d1"}

A polymer coating could reduce pore size to prevent Li dendrites and improve mechanical properties and thermal stability. Besides, inorganic ceramic particle coatings are also beneficial for enhancing electrochemical performances. Currently, much work has been done for PI separators coated with inorganic ceramic materials combined with the electrospinning method [48–50]. Figure 4a illustrates a PI nanofiber separator coated with SiO2 particles using the in situ nanoencapsulation hydrolysis method, as reported by Wu et al. [48]. SEM images clearly show that SiO2 coatings are uniformly wrapped onto the surfaces of PI nanofibers. The static contact angle of the carbonate-based electrolyte on the PI/SiO2 separator was 6.8° as shown in Fig. 4b, lower than that on Celgard and pure PI separators, indicating good electrolyte wettability of the PI/SiO2 separator. Qiao et al. [50] fabricated another PI separator reinforced with intercalated organic montmorillonite (OMMT) via solution blow spinning. In Fig. 4c, the cell with the as-prepared PI/OMMT composite separator exhibits better cycling performance (a discharge specific capacity of 131 mAh g−1 after 100 cycles at C) and rate capability (124 mAh g−1 at 2 C) than the one with Celgard-2500 separator (107 mAh g−1 after 100 cycles at 1 C and 107 mAh g−1 at 2 C). This is due to that the electrolyte wettability of the PI/OMMT composite separator is enhanced, which forms the complete Li-ion conductive route and induces higher Li-ion conductivity, resulting in the enhancement of electrochemical performances. The ceramic-coated PI separators also have good mechanical flexibility and flame-retardant properties.

Among these, PI binders with superior adhering properties, good mechanical strength, remarkable thermal stability, and outstanding electrolyte affinity are attracting wide attention. Much work reports PI binders from the perspective of molecular structure design, aiming at ameliorating different properties. To increase the Li-ion conductivity, Yao et al. [75] introduced ether functional group abundant polyethylene glycol (PEG) segments to PI structure. Compared with the carboxymethyl cellulose (CMC) binder, the discharge capacity of the silicon anode using this PI binder is as high as 2,989.7 g−1 and with few microcracks generated after cycling shown in Fig. 5a. To depress the pulverization of silicon anode, the soft and rigid copolymerized PI binder was designed [76]. The soft siloxane components possess excellent elasticity to accommodate volume changes. The rigid blocks provide a high modulus to withstand the mechanical stress generated in the silicon anode. The structural diagram of poly(siloxane imide) (PSI) binder is shown in Fig. 5b. To increase the adhesive property, PI binders with stronger adhesive functional groups were synthesized. Choi et al. [77] used highly adhesive and thermally stable co-polyimide (P84) as the silicon anode binder. In Fig. 5c, P84-based electrode was peeled off from the Cu current collector with little residues, while the surface of the Cu current collector was smooth after the PVDF-based electrode was peeled off, suggesting better adhesion with P84 than with PVDF. Besides, high adhesive capability of PI binders could keep the electrode with structural integrity, leading to the good cycling life and rate capability. Xu et al. [78] designed a kind of PI binder with the functional groups of carboxyls tethered laterally shown in Fig. 5d. Due to the interaction between carboxyls and the surface oxide layer of silicon particles, it prohibits the regenerations of solid electrolyte interface (SEI), enhancing the electrochemical performance. To sum up, the reasonable structural design of PI binders endows silicon anodes with better structural integrity and longer cycling lifespan, which lays a good foundation for the commercialization of silicon anodes.Fig. 5a PI-200 synthesis by polymerizing polyethylene glycol (PEG), trimellitic anhydride chloride (TMAC), and 4,4′-methylenedianiline (MDA).

Combining the merits of good structural integrity and high-voltage resistance, PI binders can be applied in cathodes. Similarly, the design of PI binders for cathodes is purposive. Pham et al. [79] designed a block copolymerized PI binder containing –CF3 and –COOH. Due to the –COOH, this PI binder will form strong interactions with LiNi0.8Co0.1Mn0.1O2 (NCM811), whose structure is shown in Fig. 6a. Due to the –CF3, it endows the PI binder with good thermal stability and chemical inertness. The structure of the electrode piece is shown in Fig. 6b, and the thickness of the binder layer is about 3 nm shown in Fig. 6c. Qi et al.

Then PEO/lithium bis-(trifluoromethanesulfonyl)imide (LiTFSI)/acetonitrile solution was dropped and spun on this porous PI membrane to infiltrate the pores. SEM images for the cross-sections of the PI SPE before and after cycling are shown in Fig. 7a(ii). The thickness of the PI SPE is ~ 8 μm. The electrode surface is smooth even after cycling, demonstrating Li dendrites were effectively prohibited by the PI SPE, as shown in Fig. 7a(iii). Additionally, the PI SPE-assembled pouch cell can still operate under folding, twisting, and unfolding shown in Fig. 7b(i, ii) and the pouch cell can still light an LED bulb after the nail and cutting tests shown in Fig. 7b(iii, iv). To further increase the safety, Cui et al. [87] designed a flame-retardant PI SPE with a fire-retardant additive, decabromodiphenyl ethane (DBDPE) cast on the PI matrix, whose structure is shown schematically in Fig. 7c. In Fig. 7d(i), the PE, PEO/LiTFSI, and PI/DBDPE membranes exhibit different thermal behaviors under high-temperature conditions. Due to the different melting points of the PE, PEO, and PI matrix, PE shrank, PEO melted, while PI can withstand high temperatures and maintain its original morphology. In extreme cases shown in Fig. 7d(ii, iii), the PE membrane-assembled pouch cell can no longer function when burned. The LED bulb was off after 18 s.

Second, the separator should be thermally stable with little or limited thermal shrinkage (< 5%). Further, the separator needs to be wettable by the electrolyte. Moreover, its pore distribution should be uniform to allow lithium ions to pass through. Finally, the separator should be highly insulating. Although polyethylene separators have been commercialized, their high thermal shrinkage and low trigger temperatures cause poor safety in LIBs.

Two strategies to solve the issue of pore-making can be followed. The first is by blending PI and polyolefin materials to obtain a composite separator. This approach utilizes the good processability of polyolefins to achieve uniform and well-distributed pores during heating and stretching. PIs contribute to electrolyte wettability, mechanical strength, and thermal stability. Second, a pure semi-crystalline PI can be designed and prepared.

Currently, the processing technologies for polyolefin separators are very mature. The thickness of polyolefin separators can be reduced to less than 15 μm without sacrificing their mechanical property, and the electrochemical performance can be obtained stably at room temperatures. However, two shortcomings of these separators need to be addressed [40]. First, the wettability of polyolefin separators is insufficient in accommodating any electrolyte, resulting in limited ionic conductivity owing to their hydrophobic nature. Second, the high thermal shrinkage and low melting temperature of polyolefin separators easily induce ISCs when operating at high temperatures, leading to thermal runaway. Compared with polyolefin separators, PI membranes exhibit a higher tensile strength of more than 10 Mpa, higher thermal stability up to 500 °C with little shrinkage, and good electrolyte uptake of larger than 100%. Shi et al. [41] have found that the above performances of PI separators are all better than those of PE separators. He et al.

The dielectric constant and dielectric loss of rBT/PI composites exhibited a decreasing trend with increase in frequency. This could be due to the response characteristics of different molecule groups and different chemical structures in different frequency ranges.59 Especially, the dielectric loss was relatively high in the low frequency range. The production of dielectric loss can be ascribed to the accumulation of many free charges at the internal interfaces between rBT and PI matrix. The interface polarization increases with the accumulation of free charges under the applied electric field.60 In the low frequency range, the charges have enough time to accumulate on the interfaces between rBT and PI matrix, which leads to high dielectric loss. In the high frequency range, the interfacial polarization cannot respond to the change in frequency, and thus, the dielectric constant and loss would decrease.61 In the insets of Fig. 8(a) and (b), the dielectric constant and dielectric loss of composite samples changed significantly with different rBT fillers.

A large energy-storage efficiency of about 90% (energy loss = 10%) was achieved in the composite film.

Therefore, its energy storage density (Ue) was calculated using the following formula:2Ue = 1/2εrε0Eb2where εr and ε0 are the relative dielectric constant and vacuum permittivity, respectively. Eb is the dielectric breakdown strength. The calculated results of energy storage density for different samples are shown in Fig. 12(b) and Table 2.

As discussed earlier, there are numerous defects inside the reduced BaTiO3, which are caused by lattice defects including a large number of oxygen vacancies and reduced Ti3+ ions. When rBT particles are introduced into PI to form composites, many space-charge polarization dipoles occur on the interface between rBT particles and PI due to a concentration gradient, which then contribute to the dielectric constant of composites.65,66 As shown in Fig. 8(a), a significant enhancement in dielectric constant was clearly observed at about 30 wt% rBT content. Moreover, the presence of these defects in rBT would facilitate the interface interaction between ceramic particles and polymer, which play an important role in dielectric loss and dielectric breakdown strength properties of composites.67,68 In this work, –COOH chains in PI matrix likely reacted with surface –OH groups of BT to form ester group. The existence of defects in rBT enabled the two phases to bond tightly to each other. These two factors were beneficial for the higher dielectric breakdown strength of rBT/PI composites at a certain content of rBT. However, the increase in rBT content not only enlarged the distance between rBT particles, but also extended the internal stress between the two phases. This may lead to the appearance of microcracking, and consequently lower the breakdown strength.

The ratio of Ti3+/Ti4+ increased from 1.4 to 3.0. The O1s signal displayed two components at 531.6/531.4 eV and 529.4/529.4 eV, which were assigned to lattice O and absorbed O, respectively. The ratio of lattice O/absorbed O decreased from 6.1 to 1.5. The surface area and ratios under the peaks of the BaTiO3 and rBaTiO3 ceramics are listed in Table 1. The area of Ti3+ and absorbed O of rBaTiO3 increased significantly compared to that of BaTiO3 (as shown in the Fig. 4(b)–(e) and Table 1), suggesting that most Ti4+ ions were reduced to Ti3+ ions and the oxygen vacancies increased under the reducing atmosphere (N2/H2).51 According to the XPS survey spectra of BT and rBT powders, the elemental concentration were determined by a Thermo Avantage software. The Ba, Ti, O, and C atomic percentages for BT and rBT powders (BT/rBT) are about 8.85%/7.65% (Ba3d5), 8.72%/8.33% (Ti2p), 45.54%/40.29% (O1s), and 36.89%/34.94% (C1s), respectively.

This is because of the low polarity of corresponding bonds introduced into the polymer molecular system effectively reducing the molecular polarity and the electronic polarization so as to reduce the Dk. Second, compared with the original monomers, the introduced molecule has a larger molecular weight and more complex molecular structure, increasing the asymmetry of the new molecular structure and the unit mole mass, which reduce the proportion of the easily polarized imide groups in the unit structure, thus reducing the polarity of the molecule and reducing the Dk and Df [17,18,19,20]. From the aspect of physical modification, the introduction of a hollow structure is very effective. For example, the doping of nanometer hollow microspheres or hollow particles in PAA glue introduces air of low Dk into the polymer system, thus greatly improving the dielectric properties of PIs.

In general, d-spacing reflects the average distance between polymer chain segments, and indirectly reflects the free volume in the compound system. This is due to the fact that there are many structural units in a polymer chain, so the interaction of the structural units is important for its aggregation state. With the decrease in flexible ether bonds in ODA and the increase of rigid naphthalene rings in NADA, the inward rotation of the molecular chains decreases and tends to be rigid, the π–π overlap of benzene and naphthalene rings in turn makes the molecular chains tend to be densely stacked, which eventually leads to the ordered arrangement of the polymer. It is noteworthy that the chain spacing of PI-1 is slightly increased compared with PI-0, which is likely due to the small amount of naphthalene ring structure that makes the molecular chains less regular, thus leading to the increase in free volume of the system.\", \"title\": \"Synthesis and Characterization of Polyimides with Naphthalene Ring Structure Introduced in the Main Chain\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "5a9550f9eea47e0bdf55df770cdede2cd9e3e2cf02ed6b2d97811053f6d7bab9"}

Mechanical Properties of PI Films\"], \"source_text\": \"To investigate the effect of NADA on the mechanical properties of PI films, the tensile properties (tensile strength, elongation at break and modulus of elasticity) of PI films were measured, as shown in Table 5. The introduction of the naphthalene ring structure improved the regularity of the chain segments, which enhanced the mechanical properties of PI films to some extent, with tensile strength, elastic modulus and elongation at break ranging from 81 to 96 MPa, 2.14 to 2.47 GPa and 21.16 to 16.51%, respectively. From the molecular structure analysis, the rigidity and motility of the monomer determine the physical properties of the polymer to some extent. In the PMDA/ODA/NADA system, as the molar ratio of the two diamine monomers changes, the structure and properties of the molecular chains in the PI films change accordingly. The presence of flexible ether bonds allows the PI films to consume energy better through the stretching and structural deformation of molecular chains when subjected to the same magnitude of strain, thus showing lower elastic modulus and higher elongation. In contrast, the introduction of NADA monomers results in narrower chain spacing and restricted creep space of molecular chains, while the rigid biphenyl structure makes the molecular chains more prone to brittle fracture [24]. Therefore, the mechanical property test results show that the introduction of NADA monomer can significantly improve the tensile strength and elastic modulus of PI films of this system, while the elongation at break tends to decrease. It is not difficult to find that when NADA monomer is incorporated into only 5%, it has a certain ability to improve the comprehensive mechanical properties of PI. The introduction of a small amount of rigid naphthalene ring structure is proved by XRD, which slightly increases the free volume of the polymer and gives more space for chain segments to rotate, and at the same time, brings local support points to the relatively flexible chain segments of PMDA/ODA system, which plays a kind of “rigid-flexible” effect.\", \"title\": \"Synthesis and Characterization of Polyimides with Naphthalene Ring Structure Introduced in the Main Chain\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "eeefea43901f8f0be22900db5b29365297542b3667aa7de5f09585dc4806af89"}

It is noteworthy that when the content of NADA monomer reaches 15%, the contact angle of PI-3 decreases to 70° instead, and the contact angle size of the subsequent PI-4 does not change significantly, but is still larger than that of PI-0. In addition, the water absorption test in Table 6 also indirectly proves that PI-1–PI-4 have good hydrophobicity, and their overall water absorption decreases between 0.17% and 0.34% compared to the control PI-0, where PI-2 shows a relatively lower water absorption of 0.91%. This is due to the fact that the ether bond in ODA acts as a donor of electrons and forms stable hydrogen bonds with hydrogen in water [25].

Thus, the optimum dielectric constant reaches 2.82 (PI-4 at 1 MHz) and the dielectric loss remains at 0.0065. In general, the reduction of dielectric constant and dielectric loss is usually achieved by the design of the polymer molecular structure. The introduction of low polarizability substituent groups in the polyimide chain, thus reducing the material polarizability or the introduction of asymmetric monomers or large side groups in the molecule to increase the free volume of the PI molecule. However, the decrease in the dielectric constant of this series of PIs is unusual, both in terms of the higher polarization rate due to the introduction of the conjugated structure naphthalene ring, or in terms of the XRD results showing a narrower chain spacing resulting in a lower FFV. Notably, comparing the dielectric properties of all films at 10 GHz, the dielectric constants and dielectric losses of NADA-doped monomer PI are lower than those of pure PI-0, of which PI-1 shows a lower dielectric constant of 3.01.

Conventional PIs, such as poly(pyromellitic dianhydride-4,4′-oxydianiline) (PIPMDA-ODA) usually possess Dk and Df values around 3.2–3.5 and 0.01–0.10, respectively, at the dry state [15]. In order to decrease the Dk and Df values of common PIs, various methodologies have been developed in the literature, including the introduction of substituents with low electronegativity and bulky molecular volume [16,17], or incorporation of low-Dk components, such as air, and so on [18,19,20]. However, the level of Dk and Df values (2.0–2.5@1 MHz) obtained by the former modifications usually cannot meet the requirements of high-frequency signal transmission applications. For example, according to the prediction of IMAPS (International Microelectronics Assembly and Packaging Society), the Dk values for advanced polymeric dielectrics should be lower than 2.0 at the frequency of 1 MHz in 2019 [21]. For the latter modification, the mechanical properties of the derived air-filled PI systems are usually severely deteriorated. On the other hand, from the viewpoint of effects of molecular structure on the dielectric parameters of the polymers, the existence of polar and hydrophilic imide rings in PIs is prone to increasing the Dk and Df values, especially during the servicing life in moist environments. Thus, high-temperature resistant polymers with intrinsic low-Dk and low-Df characteristics, such as polybenzoxazole (PBO) [22], liquid crystal polymer (LCP), polytetrafluoroethylene (PTFE), and so on have attracted increasing attention in 5G new dielectric materials (Figure 1). Actually, low-Dk PBOs have been widely investigated as high-performance interlayer dielectrics for microelectronic fabrication in past decades [23,24,25]. However, few works have reported on the electrospun low-Dk PBO fibrous membranes up to now [26,27,28].\", \"title\": \"Preparation and Characterization of Electrospun Fluoro-Containing Poly(imide-benzoxazole) Nano-Fibrous Membranes with Low Dielectric Constants and High Thermal Stability\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "6d4ed41f818418965040ecf6f2353b35ece5b4c93ef28b9b6361d3a1551c1fc9"}

It can be deduced from Figure 12 that at the wavelength of 457 nm, the PI NFMs showed much higher reflectance (R457) values than those of PIBO NFMs. For example, PI-1 NFM had the R457 value of 89.1%, which was 22.1% higher than that of the corresponding PIBO-1. The coloration due to the high-temperature treatment might be the main reason for the low reflectance of the PIBO NFMs. In addition, the PI-2 and PIBO-2 exhibited higher R457 values than those of the analogous PI-1 and PIBO-1, which was mainly attributed to the meta-substituted molecular structures of the former polymers. Finally, all of the PI and PIBO NFMs showed much higher R457 values than that of the PI-ref NFM (R457 = 37.3%) derived from PMDA and ODA. This is due to the presence of highly electronegative hexafluoroisopropylidene groups in the PI and PIBO polymers, which efficiently prohibited the charge transfer behaviors from the electron-donating diamine units to the electron-withdrawing dianhydride units [38]. Effects of the high-temperature procedure on the optical features of the polymer NFMs could further be reflected by the CIE Lab measurements, as could be deduced from Figure 13 and Table 2. It could be seen that the high-temperature treatment decreased the lightness (L*) and increased the yellow indices (b*) of the polymer NFMs. The polymer NFMs showed the whiteness indices (WI) with the decreasing order of PI-2 > PI-1 > PIBO-2> PIBO-1 > PI-ref.

However, the signal delay caused by various components in 5G hardware seems to be more serious with increasing frequency. It has been well established that the signal delay is closed with the dielectric constants of the materials that the signals penetrate [4,5,6]. The lower the dielectric constant (Dk) and dielectric dissipation factor (Df) of the hardware dielectric materials, the smaller the delay of the signal transmission [7]. Thus, hardware dielectric materials with low-Dk and low-Df characteristics are in demand for the 5G combination construction. Another important developing trend for research and development of 5G telecommunication is the combination with advanced display techniques, such as wearable display, health monitoring display, and so on [8].

Most common optical polymer films, such as poly(ethylene terephthalate) (PET, Tg ~ 351 K), poly(ethylene naphthalate) (PEN, Tg ~ 396 K), polycarbonate (PC, Tg ~ 423 K), and polyethersulfone (PES, Tg ~ 496 K) have limited service temperatures, and lose their optical transmittance, or deteriorate mechanically at such high manufacturing temperatures [5,6]. Temperature-resistant optical polymers therefore represent an interesting and promising class of materials because they are potential alternatives to traditional glass substrates in optoelectronic applications, with potentially better performance and durability.\", \"title\": \"Molecular Design and Property Prediction of Sterically Confined Polyimides for Thermally Stable and Transparent Materials\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "3c2ecfccff75fc11f75e4c10f39b863917f95e15ef468b6e17f0c27bb466015b"}

In the aromatic PIs, this coloration and the characteristic absorption in the visible region originate from intra- and intermolecular charge transfer (CT) between the electron-accepting dianhydride and the electron-donating diamine moiety [15]. In addition, the high chain-packing order at the nanometer level of the PI degrades its optical properties due to Rayleigh scattering. Various approaches were developed to inhibit the CT interactions of conventional aromatic PIs for optoelectronic device applications, including the use of cycloaliphatic moieties, bulky pendant groups, electron-rich bridges (such as –O–), electron-withdrawing groups, and asymmetrical structures in their backbones [16,17,18,19].

Figure 3 provides details of the quantum-chemical calculations, molecular orbital diagrams, and calculated electronic transitions of the model compounds for the three representative systems—PEsI–(CF3)1, PEsI–(CF3)2, and PEsI–(CF3)3—at the optimized S0 geometry.

Irrespective of the nature of the tetracarboxylic dianhydride, the calculated dihedral angles of a series of PEsI–(CF3)x between the –CF3-substituted phenylene ring and the imide ring at round states were in the range of 82.9–89.9°, which was significantly larger than the dihedral angles observed in the unsubstituted PEsI–H and –CH3-substituted PEsI–(CH3)x system. Note that the steric hindrance, caused by the bulky –CF3 groups directly attached to the aromatic BAT, forced the imide bond to be almost perpendicular, thereby causing significant conformational distortion of the PEsI backbones. The greater dihedral angle of the PEsI–(CF3)x model was caused by the steric hindrance of the –CF3 groups, which reduced the close chain packing, resulting in a more colorless and transparent nature. Furthermore, the more twisted structure of the PEsI–(CF3)x model resulted in largely isolated electronic states of the molecular orbitals. The number of –CF3 groups had a greater influence on the optical properties than their positions in the PEsI backbone. The results showed that the judicious introduction of electron-withdrawing –CF3 groups to the diamine moiety of PEsIs, which had considerable steric hindrance on the backbone, was quite effective at eliminating or at least reducing the characteristic coloration of the aromatic PEsIs.\", \"title\": \"Molecular Design and Property Prediction of Sterically Confined Polyimides for Thermally Stable and Transparent Materials\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "c12d938dd7e46d1ece6b0eaef6ce8d4ef51523e5a4d3f30dcceeccb84628c961"}

The dimension change exhibited a linear relationship with temperature at temperatures lower (αglass, glassy region) or higher (αrubber, rubbery region) than the Tg. Therefore, the Tg was determined by the point of intersection of the slopes corresponding to the heating and cooling processes. The Tgs of the seven PEsIs were confirmed from the plots of dimension changes, obtained from the NPT dynamics versus temperature, for temperatures ranging below and above Tg. The Tg values of the PEsI–(CH3)x series ranged from 702 to 737 K, and the PEsI–(CF3)x series ranged from 697 to 731 K, much higher than that of the PEsI–H’s (677 K). It was found that the Tg values of the PEsIs were related to the structural effects of the aromatic diamines. The PEsIs having a –CH3 substituent exhibited a higher Tg in the order of PEsI–(CH3)3 > PEsI–(CH3)2 > PEsI–(CH3)1. The results showed that the incorporation of –CH3 groups at the ortho- and meta-positions of the amino groups effectively increased Tg values, by increasing the chain rigidity of the PEsI; that is, the –CH3 groups significantly constrained bond rotation around the C–N imide bonds. The PEsI model was quite effective at increasing the Tg when the –CF3 substitution was introduced at the 3-position of the 4-aminophenyl moiety. This was supported by the fact that the highly twisted dihedral angles of the C–N imide bonds in the optimized geometry (Figure 1) of the models were 89.7°, 89.9°, and 82.9° for PEsI–(CF3)1, PEsI–(CF3)2, and PEsI–(CF3)3, respectively. The bulkier –CF3 substitution stiffened the polymer main chain more effectively than the –CH3 unit by introducing a barrier to segmental rotation. Despite the significant increase in Tg in PEsI–(CF3)1 when compared with its analogous counterpart (PEsI–(CH3)1), the Tg values in PEsI–(CF3)2 and PEsI–(CF3)3 were found to be slightly reduced.

All of the pseudo rigid-rod-like structures of the BPDA-based PEsI model molecules had low CTE values of less than 14 ppm·K−1 in the MD calculations. Considering that the CTE of current glass substrates is 5–9 ppm·K−1 [33], the CTE values of the PEsIs were within the effective range for applications as a plastic substrate. Interestingly, despite the bulky –CF3 groups interfering with chain packing, the PEsI–(CF3)x series showed a low level of CTEs similar to the PEsI–(CH3)x series. This suggested that the considerably distorted conformations in the PEsI systems effectively constrained the degree of rotational freedom at the C–N imide bonds, leading to the strong chain stiffness of the macromolecules. The steric effect was more noticeable for the PEsI–(CF3)3 because they had two different types of steric hindrance: between the imide ring and the benzene ring, and between the two benzene rings of the diamine along the ester-linkage axis. Therefore, the consecutive rigid rings along the main chains in the PEsI–(CF3)3 had significantly distorted conformations.

It shows that the MSD variation between 400 and 800 K for the PEsI–(CF3)1 system was lower than that for the PEsI–(CH3)1 system’s all-time range. The bulky –CF3 groups were generally believed to form a loosely packed PI structure, but their bulky structure effectively induced a highly twisted form in phenylimide due to the structural steric effect of the substituents. This caused the ortho –CF3 substituent of PEsI–(CF3)1 to stiffen the polymer main chain more effectively, by providing a barrier to segmental rotation. Hence, it needed more time to produce the segmental motion of PEsI–(CH3)1 than its counterparts. The slope of the MSD above the Tg value was much higher than that below Tg, indicating that each of the PEsI chains had higher mobility above the glass-transition region. This abrupt change between the two temperature zones, based on the Tg, can be seen more clearly in Figure 5b, where the MSD is plotted as a function of temperature at 50-ps time periods.

The PEsIs had a different peak position and relative proportion for ΦCONCO-Ph (the torsion angle between the imide and phenyl rings) depending on their molecular structures. PEsI–H (Figure S5) and PEsI–(CH3)1 had many peaks over the range of ±15° to ±165°, but there were only two major peaks located in the ±90° range in other PEsI systems. These were attributable to the ortho- and/or meta-substitution in the aromatic diamine compounds, which induced significant steric hindrance around the C–N imide bonds. Notably, the steric hindrance between adjacent groups, derived from the 3-trifluoromethyl moiety, greatly restricted the torsional bond rotation of the C–N imide bonds. Actually, the probability distribution of the torsion angle at ΦCONCO-Ph with temperature was narrower in the PEsI–(CF3)x series. This result was consistent with the torsion angles obtained in the molecular structures of the stabilized model compounds (Figure 1). To investigate the effect of temperature on torsion-angle distribution, the torsion-angle distributions of the PEsI series were obtained at 400 and 850 K. These distribution functions showed peaks at the same position for the two temperatures, and had a wider distribution at higher temperatures; however, they showed a slight difference in probability densities.

Quite recently, we developed new aromatic PEsIs using an ester-bridged aromatic diamine with dimethyl groups at the ortho-position of the amino groups [22]. Although this PI has one of the lowest coefficients of thermal expansion (CTE) among aromatic PIs, by controlling the dihedral torsion angle between the dimethyl-substituted phenylene ring and the imide ring, it still has coloration. Thus, we continued efforts to develop PIs with high transparency, as well as high Tg and low CTE values, based on the highly twisted conformations of the phenylimides.\", \"title\": \"Molecular Design and Property Prediction of Sterically Confined Polyimides for Thermally Stable and Transparent Materials\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "23ccc4547d121222ef9814ac8d36a9ca884a76ee7b326006b0b230dd976c9237"}

This type of synthesis involves long cycles, and limitations imposed by experimental conditions. As a result, it is undesirable and expensive to attempt the synthesis of all possible PI structures without a suitable methodology of increasing the potential for success. For this reason, the ability to predict the characteristics of polymer materials from their chemical constitution is particularly important for the selection and design of new high-performance materials. Computer-aided modeling consequently became a standard method for studying complex polymer systems, and has now widely used to predict the physical properties of polymer materials. The modeling is useful for the suggestion of potential materials with predefined characteristics. For example, molecular dynamics (MD) simulation is a well-known way of studying bulk polymers at the molecular level [23,24]. In particular, it allows thermodynamic behavior, such as the glass-transition temperature (Tg) and the coefficient of thermal expansion (CTE) of a candidate polymer, to be studied effectively [25,26,27,28].\", \"title\": \"Molecular Design and Property Prediction of Sterically Confined Polyimides for Thermally Stable and Transparent Materials\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "905f7ab98b49baba6b1af2269be8992640b5ec071ee7fbe6aa7b5d7f31e2647e"}

The complexation, as a kind of highly polarized units, occurred by the d-π bonds between the unoccupied d-orbitals of Cu(II) and the lone electron pairs of N atoms in PyBI segments. Incorporation of the metal-bonded fraction enhanced the orientational polarizability in the resulting PIs and, thus, improved their dielectric constant.

Among them, the value of 50% Cu-PI increased 43% than that of the one without Cu-complex. Moreover, the dielectric constant was found to be dependent on the frequency of external field. The values slightly decreased as the frequency increased, because alternating in dipoles could not keep up with changed electric field, resulting in a slight decrease in the orientational polarization at high frequency. As shown in Figure 3b and Table 1, the dielectric loss of PIs prepared here was below 1% at 1 kHz and room temperature.

This was induced by the typical p-type NOT gate operation [32]. A high VIN bias condition creates a low current characteristic because the gate-source voltage of the driving transistor is small; therefore, the load transistor is strongly turned on. Thus, VOUT is pulled down to zero. In contrast, a low VIN bias condition leads to similar values between the gate and source voltages of both the drive and load transistors.

The reason for this phenomenon is shown through the results of ultraviolet-visible spectroscopy, after the introduction of GAPD, the intermolecular charge transfer complexation is enhanced, and the increase in the intermolecular force makes it easier for molecular chains to form regular and compact crystal regions with molecular arrangement, so the overall crystallinity is higher.

This is a common phenomenon and the reason for this is that when the frequency is low, the dipole in the material has sufficient polarization time, while in the high-frequency electric field, the polarization of the dipole cannot keep up with the change of the electric field, so the degree of polarization is low, which represents the decrease in the macro dielectric constant.

However, research shows that the hindrance to the formation of the crystal lattice is small, the polarization is fully established, and the molecular polarization in the amorphous region is relatively difficult to establish.

As the conductivity of the polymer dielectric is quite low, the dielectric loss tangent is often used to characterize the dielectric loss characteristics of materials. It can be seen in Figure 8 that the dielectric loss characteristics of the four samples are slightly different in the low frequency region and greatly different in the high frequency region. With the increase of frequency, the tangent value increases continuously in the range of 50 Hz to 1 MHz and decreases slightly in the later stage, and the tangent of the frequency dielectric loss increases slowly in the low frequency range. This is because the dipole can keep up with the change of electric field in the low frequency region, so the dielectric loss is low. With the increase in frequency, the polarization cannot keep up with the change of electric field in the high frequency region, and the dipole steering is affected by resistance, leading to the increase in dielectric loss [10]. When the frequency is much too high, the relaxation polarization is too late to be established, and the displacement polarization is the dominant one, thus the maximum value appears. For the four samples, in the high-frequency range (1 kHz ~ 100 kHz), the addition of GAPD leads to an obvious reduction of dielectric loss, this is because the addition of GAPD causes an increase in polymer crystallinity, which is conducive to the polarization steering of dipole to reduce the heat generation caused by resistance under an alternating electric field.\", \"title\": \"High-Frequency Surface Insulation Strength with Nanoarchitectonics of Disiloxane Modified Polyimide Films †\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "e43cd9ca40f58dfadcbeaed5337fe945be2720fb9f838a744cf0a5b061bb973e"}

However, BOPP can only operate at temperatures below 85 °C, above which the leakage current rises significantly while the breakdown strength drops sharply, resulting in a significant reduction in the capacitor’s reliability [5]. To satisfy the demands of applications in harsh conditions where the working temperature is higher than 125 °C—such as electric vehicles and aerospace power electronics—it is of significance to develop a new generation of polymer-based dielectrics for high-temperature energy storage [6].\", \"title\": \"Polyimide Nanodielectrics Doped with Ultralow Content of MgO Nanoparticles for High-Temperature Energy Storage\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "1d9a1780fc84b0a67f53217ebd225ee40126540a491266e26aa57334c50b3942"}

Introduction\"], \"source_text\": \"To address the conduction loss issue of polymer dielectrics at high temperatures, plenty of strategies have been attempted in the past few decades [11,12,13,14,15]. Polymer–oxide composites are a very interesting and important research topic with various applications [16,17]. One strategy is constructing a nanoscale inorganic coating with a wide bandgap on the surface of the polymer to inhibit charge injection and, thus, reduce the leakage current [11,18]. Li et al. demonstrated that the capacitive performance of several polymer dielectrics at high temperatures—including PEI, PC, and PI—can be significantly improved by SiO2 coating [11]. Crosslinking is another strategy to improve the breakdown strength and the efficiency of polymer dielectrics at high temperatures [14,19,20]. Wang et al. reported crosslinked fluoropolymers exhibiting a superior Ue of 2.67 J cm−3 with a η of more than 90% at 400 MV m−1 and 150 °C [14]. They attributed this remarkable improvement to efficient charge-trapping by a range of the molecular trapping centers resulting from the crosslinked structures. Nevertheless, although these methods have been proven to be effective in improving the high-temperature storage performance of polymers, they are challenged by complex and rigorous manufacturing processes. In this regard, nanodielectric strategies incorporating wide-bandgap (Eg) nanofillers are advantageous, since they can not only successfully inhibit the leakage current in the polymer matrix under high electric fields and elevated temperatures, but also have flexible designability and good compatibility with existing manufacturing technology [21,22,23]. To date, the two most studied nanofillers are boron nitride nanosheets (BNNSs, Eg = 5.9 eV) and alumina (Al2O3, Eg = 8.6 eV), while attempts using other wide-bandgap inorganic fillers are quite limited [24,25,26]. Since magnesium oxide (MgO) features a large bandgap of 7.8 eV and a high dielectric constant of 9.7, it is reasonable to believe that its introduction can benefit both the dielectric constant and the breakdown strength of the polymer nanodielectrics [27]. There are a lot of studies on the electrical properties of composites with nanometer MgO as fillers [28,29,30,31]. However, to the best of our knowledge, there is little research on the utilization of MgO to tune the dielectric energy storage properties of polymer nanodielectrics at high temperatures.\", \"title\": \"Polyimide Nanodielectrics Doped with Ultralow Content of MgO Nanoparticles for High-Temperature Energy Storage\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "a9a63b8a61783ded9e35977d2808554a8c0bfa11e14238362c875276e78fca9f"}

It can be seen that the MgO nanoparticles are uniformly distributed in the PI matrix, without obvious agglomeration, which is further confirmed by the energy-dispersive X-ray spectrum (EDS) of magnesium shown in Figure 1c. To study the possible structural changes caused by MgO nanoparticles, XRD patterns of the neat PI and MgO–PI nanocomposite films with 0.1 vol% and 0.3 vol% MgO were compared, as shown in Figure 1d. The neat PI exhibits a broad peak centering at 2θ = 20.5°, which is related to the scattering of the interchain spacing in its amorphous phase [33]. The 0.1 vol% and 0.3 vol% MgO–PI nanocomposite films also have a wide diffraction peak, with the position centering at 2θ = 19.5° and 20.1°, respectively. Since lower XRD peak position corresponds to larger interchain spacing, it is suggested that incorporation of the MgO nanofiller can enlarge the interchain spacing of PI—especially at ultralow content.

Similar to the neat PI, all of the MgO–PI nanocomposite films exhibit little fluctuation in their dielectric constant over the whole frequency range of 102 to 106 Hz, revealing the good frequency stability of their capacitive performance. The dielectric constant of the MgO–PI nanocomposite films first increases and then decreases with the increase in the MgO content, and reaches the maximum at 0.1 vol%. Specifically, the dielectric constant of the 0.1 vol% MgO–PI nanocomposite film is 4.12 at 1 kHz, which is enhanced by about 16% relative to that of the neat PI (3.55). On the other hand, all of the MgO–PI nanocomposite films maintain a relatively low dielectric loss analogous to that of neat PI. It should be mentioned that such large permittivity enhancement by ultralow MgO content while maintaining low dielectric loss cannot be well explained by the effective medium theory alone [35]. Instead, it is more reasonable to attribute the increase in permittivity to the enlarged interchain distance, as revealed by the XRD results above. Figure 3b shows the dielectric constant and tan δ of the neat PI film and MgO–PI nanocomposite film as a function of temperature, ranging from 25 to 150 °C. The dielectric constant of the neat PI shows some decline with the increase in the temperature—especially in the range of 25 to 100 °C—probably due to the adverse effect of absorptive moisture. In comparison, the MgO–PI nanocomposite films show a relatively stable dielectric constant in the range of 25 to 150 °C, with the change being no more than 6.25%. As shown in Table 1, we compared the dielectric constant changes of MgO–PI at 25°C~150 °C with those of other, similar materials [36,37,38,39,40]. It is not difficult to find that the dielectric constant of MgO–PI changes at temperatures much lower than others.

Obviously, the energy storage density is positively correlated with the square of the material’s breakdown field strength. Since dielectric materials are inhomogeneous in reality, different internal microstructures, defects, electrode states, material sizes, and measurement conditions may cause dielectric materials to exhibit different breakdown field strengths. The breakdown data can be evaluated using the Weibull distribution, and the formula is P(E)=1−exp(−(E/Eb)β), where P(E) is the cumulative probability of dielectric breakdown, E is the experimental breakdown strength, Eb is the characteristic breakdown strength when the cumulative breakdown probability is 63.2%, and β is the shape factor related to the sample dispersion [42]. A number of high-voltage breakdown tests were carried out, and the Weibull breakdown field strength distribution of the neat PI and MgO–PI nanocomposite films at 150 °C is shown in Figure 4a. In addition, the Weibull breakdown field strength and β of MgO–PI nanocomposites as a function of MgO content are plotted in Figure 4b. It can be clearly seen that the breakdown field strength of all MgO–PI nanocomposite films is higher than that of PI films. When the MgO content is 0.1 vol%, the breakdown field strengths of the composite films reach their maximum values (469 MV m−1), which are 1.5 times that of PI (317 MV m−1). Moreover, it can also be seen that the β value of the nanocomposite film is slightly higher than that of the neat PI film, indicating that the composite film has higher breakdown reliability. The superior breakdown strength of MgO–PI nanocomposite films may be due to MgO with a large bandgap being dispersed homogeneously in PI, effectively hindering the conduction loss.

Charge–discharge efficiency (η) is defined as the ratio of Ue and U. Figure 5a shows (D–E) loops of the neat PI film and the MgO–PI nanocomposites at 150 °C and 300 MV m−1. Apparently, the MgO–PI nanocomposite films display relatively slimmer hysteresis loops compared to the pristine PI film, indicating that the nanocomposite films deliver a lower energy loss and, thus, a higher η. In addition, the remanent polarization value was drastically reduced from 1.1 μC cm−2 for the pure PI to 0.12 μC cm−2 for the 0.1 vol% MgO–PI nanocomposite film, attributed to the incorporation of a slight amount of MgO, which can significantly suppress the loss of PI at high temperature.

However, it has been found that these high-Tg polymers typically suffer from considerable electric conduction loss under both high electric fields and high temperatures, causing remarkable temperature increases that, in turn, aggravate the conduction loss that grows exponentially with the temperature. This ultimately leads to a sharp drop in breakdown strength and, thus, a significantly reduced discharge energy density [7,9].Previous studies have shown that some commercial engineering plastics—such as aromatic Kapton PI, polyetherimide (PEI), fluorene polyester (FPE), polycarbonate (PC,) and polyethylene naphthalate (PEN)—can only discharge an energy density (Ue) of 0.24, 0.89, 0.26, 0.14, and 0.26 J cm−3, respectively, at 150 °C when the charge–discharge efficiency (η) is 90%, which are far from the requirements of practical application [10].\", \"title\": \"Polyimide Nanodielectrics Doped with Ultralow Content of MgO Nanoparticles for High-Temperature Energy Storage\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "3ab6b1a9b5700eadfcde03037f8b90572a0d6ac1093dc0c34becc2e299336b2d"}

This indicates that the MgO–PI nanocomposite films can maintain excellent heat resistance, similar to the neat PI.

For example, the CPI films derived from fluoro-containing dianhydride, 4,4′-hexafluoroisopropylene diphthalic anhydride (6FDA), and fluoro-containing diamine, 2,2′-bis(trifluoromethyl)benzene (TFMB) showed a CTE value of 82 × 10−6/K [4]. The semi-alicyclic CPI films derived from hydrogenated pyromellitic anhydride (HPMDA) and 4,4′-oxydianiline (ODA) had a CTE value of 57.1 × 10−6/K [5]. Comparatively, the first generation of silicon-based semiconductor chips showed a CTE value of 3.0 × 10−6/K [6], and the third generation of silicon carbide (SiC)-based chips showed a CTE value of 4.2 × 10−6/K [7]. The optical sodalime glass (SLG) and the new generation of ultrathin glass (UTG) showed CTE values of 8.9 × 10−6/K and 7.2 × 10−6/K, respectively [8]. The mismatch between the CTE values of CPI films and the inorganic components might induce internal stress during the fabrication of the optoelectronic devices, which might result in delamination, cracking, warpage, and other reliability issues [9].

Various methodologies based on the molecular design of the functional alicyclic dianhydride or the aromatic diamine monomers have been proposed and carried out to reduce the CTE values of the semi-alicyclic CPI films. For instance, an alicyclic dianhydride monomer having a rigid cyclopentanone bis-spironorbornane structure (CpODA) was developed, and the derived CPI films showed reduced CTE values in the range of 17 × 10−6/K to 57 × 10−6/K [17]. An alicyclic dianhydride, octahydro-2,3,6,7-anthracenetetracarboxylic dianhydride (OHADA) was recently reported, and the CPI films based on the dianhydride monomer showed a CTE value as low as 41.5 × 10−6/K [18]. An alicyclic dianhydride monomer containing a rigid cyclobutane unit, 1,3-dimethyl-1,2,3,4-cyclobutane tetracarboxylic dianhydride (DM-CBDA), was synthesized to develop low-CTE CPI films [19]. The CPI film based on DM-CBDA and TFMB exhibited a CTE value of 28.1 × 10−6/K, which was much lower than that of the 6FDA-TFMB system (CTE = 82 × 10−6/K). For the diamine monomers, various rigid-rod units have been introduced into the molecular structures of the compounds so as to reduce the CTE values of the derived semi-alicyclic CPI films. Amide (-CONH-) or benzanilide (-Ph-CONH-Ph-) structural units have been proven to be the most effective substituents for achieving this target [20,21,22]. In our previous work, the aromatic diamines containing amide linkages were developed, and the CPI films based on the diamines and the hydrogenated pyromellitic anhydride (HPMDA) showed reduced CTE values as low as 27.7 × 10−6/K [23]. However, the optical properties of the derived low-CTE CPI films deteriorated with the incorporation of the amide components. In view of this defect of the common CPI films derived from the amide-containing diamines, a novel aromatic diamine simultaneously containing rigid-rod benzanilide and highly electronegative trifluoromethyl (–CF3) units, 2,2′-bis (trifluoromethyl)-4,4′-bis[4-(4-aminobenzamide)]biphenyl (ABTFMB) was designed and developed in Hasegawa’s group and was widely used to develop high-performance CPI films [24,25,26].\", \"title\": \"Preparation and Characterization of Light-Colored Polyimide Nanocomposite Films Derived from a Fluoro-Containing Semi-Alicyclic Polyimide Matrix and Colloidal Silica with Enhanced High-Temperature Dimensionally Stability\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "a965c9883e93dcd0771268639df7465fdf063b88bcccde8b7f7e75a71737caf3"}

After all, maintaining the intrinsic optical transparency and low color parameters of the pristine optical films is always the prerequisite in practical applications. Nano-sized silica fillers have been one of the most important functional fillers to compensate for the defects of the common polymeric films, such as the relatively poor dimensional stability at elevated temperatures, the low modulus, the low flame retardancy, and so on. However, the common silica nanoparticle is usually aggregated in the optical film matrixes, especially at high loading amounts. Thus, special surface treatments and additional dispersion treatments are usually required during the fabrication of the nanocomposite films. Even by these methodologies, the loading proportions of the nano-fillers in the final composite films were usually controlled at a relatively low level (<10 wt%). By contrast, colloidal silica (cSiO2) or silica sol nanoparticles dispersed in water or organic solvents exhibited good dispersion and distribution in the polymer films. Usually, the functionalization of the SiO2 surface introduces organic groups that make the colloidal SiO2 particles surface-active and sterically stable. The particles are amorphous, but the particle surface is composed of silanol groups, which is the hydroxyl group connected to the silicon atom. The increased surface activity of SiO2 particles enables them to act as an emulsifier. In general, silica sols are an aqueous suspension of colloidal SiO2 particles. In order to endow the silica sols with good compatibility with the ABTFCPI-0 matrix, the commercially available aqueous cSiO2 dispersion was modified by solvent replacement in the current work, in which the water was replaced by DMAc.\", \"title\": \"Preparation and Characterization of Light-Colored Polyimide Nanocomposite Films Derived from a Fluoro-Containing Semi-Alicyclic Polyimide Matrix and Colloidal Silica with Enhanced High-Temperature Dimensionally Stability\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "fb710808af2f524c4f091863febf042977a6cb5319179fdb4d5dfc0d7b566f79"}

The pristine ABTFCPI-0 film showed a CTE value of 32.7 × 10−6/K in the range of 50~250 °C (Table 3). This value ranked lower in all of the semi-alicyclic PI films, which are also the effects of the rigid-rod benzanilide and biphenylene units in the polymers. The incorporation of rigid amide or benzanilide linkages has been widely used to develop CPI films with low-CTE features. When incorporated with the cSiO2 nanoparticles, the CTE values of the CPI films further decreased. For example, the ABTFCPI-30 film showed a CTE value of 25.4 × 10−6/K, which was 22.3% lower than that of the pristine ABTFCPI film. In addition, it can be seen from the inserted picture that the ABTFCPI-25 and ABTFCPI-30 films with the higher loading contents of cSiO2 fillers showed much lower dimensional expansion at elevated temperatures. Undoubtedly, the inorganic cSiO2 fillers efficiently increased the dimensional stability of the nanocomposite films.

Composite films seem to be one of the few feasible pathways to achieve this target. Combination with inorganic nanofillers with low thermal expansion characteristics, such as silica (SiO2), has been proven to be an effective way to further reduce the CTE values of the CPI films [27,28,29,30]. However, the incorporation of nanoparticles might deteriorate the optical transparency of derived composite films. This requires careful design of the morphology, particle size, and surface pretreatment of the nanoparticles. Recently, a special class of silica nanoparticles, colloidal-type silica, has been widely used in the modification of CPI films [29]. In practical applications, colloidal silica (cSiO2) nanoparticles are usually dispersed in a good solvent, such as N,N-dimethylacetamide (DMAc), for the CPI film manufacturing, and thus can form uniform dispersion and distribution in the CPI matrix after high-temperature imidization or curing process. The unique physical and chemical properties of the colloidal silica nanoparticles make them achieve a higher loading proportion in the CPI matrix than the traditional nano-silica particles, which can effectively reduce the CTE values of the composite films while maintaining the inherent optical properties of the CPI matrix film to a large extent. Yu and coworkers reported the highly transparent PI/silica hybrid optical thin films based on the wholly aromatic fluoro-containing PI matrix and cSiO2 fillers [30,31]. The derived nanocomposite films showed good optical transparency. Although the wholly aromatic fluoro-containing PI films have been widely used as the matrix for the development of the PI/cSiO2 nanocomposite films, the CPI/cSiO2 films based on fluoro-containing semi-alicyclic PI films have been rarely reported in the literature.\", \"title\": \"Preparation and Characterization of Light-Colored Polyimide Nanocomposite Films Derived from a Fluoro-Containing Semi-Alicyclic Polyimide Matrix and Colloidal Silica with Enhanced High-Temperature Dimensionally Stability\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "d976c68a9bce74a011e85cc5353f4a7d130635413276306ad752c24dc4de42fa"}

The amorphous colloidal silica nanoparticles showed the absorption peak at 2θ = 22.1° (d spacing = 4 Å), which was in good agreement with the data reported in the literature [33].

After stirring at room temperature for 10 min, the pale-brown FDA solution was obtained. Then, ccHPMDA (22.417 g, 0.1 mol) dianhydride was added into the reaction system with one batch via the adding funnel. Additional GBL (71.8 g) was added, and we washed all of the dianhydride into the reaction mixture. The stirring speed was then increased from 150 rpm to 300 rpm until a viscous solution was obtained. A moderate heat-releasing phenomenon was detected. Then the mixing speed was decreased to 200 rpm. Toluene (200 g) and isoquinoline (0.5 g) were added to the reaction system, after which the reaction mixture was heated under nitrogen protection. When the temperature of the reactant reached 130~140 °C, the toluene-water azeotrope was found to be trapped in the Dean–Stark trap. The water by-products were continuously distilled out of the reaction mixture to promote increases in the molecular weights of the resin. No water was observed after 6 h and the residual toluene was distilled out the system until the inner temperature of the reactant reached 180 °C. The reaction was maintained at this temperature for another 6 h and then cooled to room temperature. A viscous solution with a pale reddish-brown appearance was obtained.

Introduction\"], \"source_text\": \"Applications as optical components in various high-tech devices have been becoming one of the most important hot topics in relation to the research and development of high-performance polyimide (PI) films [1,2,3,4,5]. In practical optical applications of the PI films, such as optical fiber communications, optical waveguides, liquid crystal display and rigid or flexible organic light-emitting diode displays, adjustments of the optical parameters of PI films, including optical transparency, color parameters, refractive indices (n), birefringence (Δn), optical retardations and so on, play important roles for achieving the desirable performance of the optical devices [6]. In particular, in flexible electronics areas, including flexible display, flexible solar cells, flexible electronic skins, and flexible and wearable devices, the optical properties of PI films have to be elaborately tailored so as to meet the different property requirements [7,8,9]. Among the various optical properties of the PI films, the adjustments of the optical retardations (Rth) of the films have been paid increasing attention in recent years. For example, in a flexible active matrix organic light-emitting diode (AMOLED) display device, the optical film used as a cover window needs to have the lowest optical anisotropy possible in order to reduce the display defects [10]. However, in thin film transistor-driven active matrix liquid crystal display (TFT-LCD) devices, some optical films should possess high optical anisotropies [11]. In view of the potential ability to eliminate display nonuniformities in the cover window films for flexible AMOLED, polymeric optical films with low Rth (low-Rth) and high thermal stability features are highly desired [12].\", \"title\": \"Design, Synthesis and Properties of Semi-Alicyclic Colorless and Transparent Polyimide Films with High Glass Transition Temperatures and Low Retardation for Potential Applications in Flexible Electronics\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "bb3b1bbff23ed65d1c02d21c52e2b2486e0e8fcc11ceeaa11ab02870fe1f139c"}

Introduction\"], \"source_text\": \"It has been well established that the Rth values of polymer films are mostly related to the chemical structures and fabrication processes. The Rth parameter is usually expressed via the equation Rth = Δn × d, where Δn stands for the birefringence of the polymer film and d represents the thickness of the film. Some polymers with rigid structures show high birefringence after casting the film on substrates. Standard aromatic PI films, such as the unstretched species derived from pyromellitic dianhydride (PMDA) and 4,4′-oxydianiline (ODA) (PIPMDA-ODA), and the ones from rigid-rod 3,3′,4,4′-biphenyl- enetetracarboxylic acid dianhydride (BPDA) and para-phenylenediamine (PDA) (PIBPDA-PDA), showed high Δn values of 0.077 and 0.22 at a thickness around 20 μm, respectively [13], indicating Rth values over thousands of nanometers. This is usually unacceptable for specific optical applications. In addition, the fabricating conditions, including the uniaxial stretching [14,15,16], biaxial stretching [17], drying or imidization procedures [18], and other factors, might severely affect the optical anisotropies of the derived PI films. Excluding the influence of processing conditions on the optical anisotropies of the PI films, the molecular structures of PI films are also important factors affecting the optical anisotropies. It was reported that PI films with rigid molecular skeletons, such as PIBPDA-ODA, usually show relatively high Rth values, while PI films with less rigid or flexible units, such as the ones containing flexible ether linkages, isopropyl or hexafluoroisopropyl groups, and so on, might possess lower Rth values. What is more, the PI films derived from preimidized and organo-soluble resins, such as the ones based on 3,3′,4,4′-benzophenonetetracarboxylic acid dianhydride (BTDA) and 5(6)-amino-1-(4-aminophenyl)-1,3,3-trimethylindane (PIDA) (PIBTDA-PIDA), usually showed much lower optical anisotropies compared with those derived from the poly(amic acid) (PAA) precursors due to the potentially increasing optical anisotropies in the films during the high-temperature imidization process [19]. Generally speaking, in order to develop PI films with low optical anisotropies or low retardation features, resins with preimidized structural characteristics together with flexible molecular skeletons are highly preferred [20]. Recently, Li and coworkers reported colorless PI films with optical retardation as low as 42 nm at the thickness of 21 μm achieved by the polymerization of flexible 4,4′-(4,4′-isopropylidenediphenoxy)bis(phthalic anhydride) (BPADA) and bis[4-(3-aminophenoxy)phenyl]sulfone (mBAPS) [21].

Meanwhile, bulky fluorene groups could usually endow the polymers with high thermal stability due to the restricted internal rotations around the fluorene units, for which a large sweep volume is usually required for the free rotational motion [26]. On the other hand, alicyclic units have also been widely used to develop polymer optical films with low Rth characteristics. Polymer films containing alicyclic units, such as the cyclo-olefin polymers (COPs), could achieve almost zero retardation and an optical transmittance over 90% in the visible light region (400~700 nm) [27]. The semi-alicyclic PI films derived from the alicyclic dianhydride of CpODA and the aromatic diamine of 3,4′-oxydianiline (3,4′-ODA) exhibited low Rth values of 1.7 nm [28].

These series of hydrogenated pyromellitic dianhydrides (HPMDA) or cyclohexane dianhydrides (CHDA) have been thoroughly studied in Hasegawa’s pioneering works [29,30,31], and the effects of stereoisomerism in the dianhydride on the polymerization reactivity and properties of the derived polymers have been revealed. Among the seven stereoisomers of HPMDA dianhydride revealed up to now [32], three species, including 1S,2R,4S,5R-HPMDA (H-PMDA or ccHPMDA), 1S,2S,4R,5R-HPMDA (H′-PMDA or ttHPMDA), and 1R,2S,4S,5R-HPMDA (H″-PMDA or ctHPMDA), have now been investigated as monomers in the research and development of high-performance PIs. It has been concluded that the stereoisomerism in the dianhydrides indeed affects the thermal and optical properties of the afforded PIs. Meanwhile, the polymerization reactivities of the different HPMDA dianhydrides are not only dependent on the steric structures of the dianhydrides, but also on the characteristics of the diamine monomers used. In the current work, the potential polymerization reactivities of the dianhydride and diamine monomers were roughly compared via theoretical simulation. The reactivity of the monomers was calculated according to the density functional theory (DFT)/B3LYP methods with Gaussian 09 software using the 6–311 G (d, p) basis set [33]. The lowest unoccupied molecular orbital (LUMO) energy levels (εLUMO) for the HPMDA dianhydrides and the highest occupied molecular orbital (HOMO) energy levels (εHOMO) for the fluorene-containing or 6FODA diamines were calculated, and the results are shown in Figure 1 and Figure 2, respectively. It was reported in the literature that the εLUMO value of one dianhydride and the εHOMO value of one diamine were closely related with their polymerization reactivity. A lower εLUMO value for the dianhydride and a higher εHOMO value for the diamine could roughly indicate the higher reactivity of the monomers [34]. According to Figure 1, H′-PMDA (ttHPMDA) with the lowest εLUMO value (−1.81 eV) might possess the highest reactivity among the three stereoisomers, which is in good agreement with the literature [31]. The reactivities of the three compounds decreased in the order of H′-PMDA (ttHPMDA) > H″-PMDA (ctHPMDA) > H-PMDA (ccHPMDA). With the same simulation procedure, the aromatic pyromellic dianhydride (PMDA) showed the εLUMO value of −4.17 eV, indicating a much higher polymerization reactivity than those of the alicyclic HPMDA. Thus, a high-temperature polycondensation procedure might be needed for the HPMDA-based PIs. As for the diamines, the reactivities of the three monomers decreased in the order of FDA (−5.39 eV) > FFDA (−5.59 eV) > 6FODA (−5.75 eV), according to the εHOMO values. These values are a bit lower than that of the common aromatic diamine of 4,4′-oxydianiline (ODA) (εHOMO = −5.08 eV), indicating the inferior reactivities of the fluorene-containing and fluoro-containing diamines. In the current work, ccHPMDA and ctHPMDA were chosen to polymerize with the three aromatic diamines, respectively.\", \"title\": \"Design, Synthesis and Properties of Semi-Alicyclic Colorless and Transparent Polyimide Films with High Glass Transition Temperatures and Low Retardation for Potential Applications in Flexible Electronics\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "fe0c67427cb763afb1d4c6f6a27a3afca04126254cb94c56dbdfe013ed9dedf5"}

Due to the relatively lower reactivities of the utilized monomers, a high-temperature polymerization procedure was used to prepare the CPI resins. All the polymerization systems remained homogeneous, and no gelling or precipitation were observed, indicating the good solubility of the CPI resins in the reaction medium. This is mainly attributed to the non-conjugated alicyclic structures in the dianhydride units and the bulky fluorene or trifluoromethyl substituents in the diamine units. The inherent viscosities ([η]inh), molar mass and solubility of the CPI resins were measured, and the results are shown in Table 2. The entire resins exhibited moderate to high molar mass, with [η]inh values higher than 0.51 dL/g and Mn values over 5.0 × 104 g/mol. In addition, all the polymers showed PDI values lower than 1.70, indicating the minimal side reactions during the polymerization. For the fluorene-containing CPI resins, the ones derived from ctHPMDA showed higher Mn values than those derived from ccHPMDA. For example, CPI-IIa (ctHPMDA-FDA) had the Mn value of 11.41 × 104 g/mol, which was much higher than that of CPI-Ia (ccHPMDA-FDA, Mn = 8.11 × 104 g/mol). Meanwhile, the CPI resins based on FDA exhibited higher Mn values than those derived from FFDA. This is consistent with the polymerization reactivities’ prediction as shown in Figure 1 and Figure 2.

The fluorene-based CPI films showed Tg values that were more than 100 °C higher than those of the 6FODA-based ones. For example, the CPI-Ia (ccHPMDA-FDA) film had a Tg value of 437.1 °C, which is 128.6 °C higher than that of the analogous CPI-ref1 (ccHPMDA-6FODA) (Tg = 308.5 °C). The high-Tg feature of the fluorene-containing CPI films is mainly due to the non-planar structures in the FDA and FFDA diamine moieties caused by the bulky and rigid fluorene units, which efficiently increased the barrier against the free rotations and movements of the molecular chains at elevated temperatures. With respect to the effects of the stereoisomerism of the dianhydrides on the Tg values of the polymers, no obvious differences were observed for the ccHPMDA- and ctHPMDA-derived CPIs in the DSC measurements. Similar results were also observed in the DMA measurements, as shown in Figure 11. The Tg values of the polymers were identified as the peak temperatures of the tan δ plots. The fluorene-based CPI films exhibited Tg values in the range of 446.0~453.2 °C, which were also obviously higher than those of the 6FODA-based polymers (Tg ≈ 317 °C). In addition, the fluorene-containing CPI films could maintain most of their initial storage modulus up to 400 °C, while the modulus of the 6FODA-derived ones dramatically dropped when the temperature was higher than 300 °C.

The fluorene-containing CPI films showed slight thermal expansion before 400 °C and then shrunk sharply when the test temperature further increased, indicating the occurrence of the glass transition behaviors and the ordered rearrangements of the molecular chains. When this course finished, the CPI films expanded again, and their dimension change showed a nearly linear increasing trend. For the fluoro-containing CPI-ref1 and CPI-ref2 systems, this phenomenon occurred at around 300 °C, indicating the inferior thermal resistance of the polymers. In the temperature range of 50~250 °C, the fluorene-based CPI films showed linear coefficients of thermal expansion (CTE) values of 57.4 × 10−6/K~66.5 × 10−6/K, which were comparable to those of the 6FODA-based films (60.7 × 10−6/K for CPI-ref1 and 62.2 × 10−6/K for CPI-ref2). The CPI films derived from ctHPMDA showed somewhat higher CTE values than those based on the analogous ccHPMDA. This might be due to the relatively looser packing of molecular chains in the ctHPMDA-PI systems, which arose from the steric effects of the dianhydride. The higher CTE values for the semi-alicyclic CPI films have been cited as one of the main defects in relation to applications in advanced optoelectronic fields. This is mainly ascribed to the non-conjugated and less interactive molecular chain structures in the cyclohexane dianhydride units.

All the CPI films exhibited very pale colors and good optical transparency. Figure 14 presents the UV-Vis spectra of the CPI films and the optical data are tabulated in Table 4. The CPI films showed UV cutoff wavelengths (λcut) in the range of 287~304 nm, indicating good optical transparency in the visible light region (wavelength: 400~760 nm). The optical transmittances of the CPI films at 400 nm (T400) and 450 nm (T450) were all higher than 80% at the thickness of 20 μm. Basically, the fluorine-containing 6FODA-PI films exhibited higher optical transmittances than those of the fluorene-PI counterparts. For example, the CPI-ref1 (ccHPMDA-6FODA) film showed a T400 value of 84.9%, which is higher than those of analogous CPI-Ia (ccHPMDA-FDA, T400 = 82.1%) and CPI-Ib (ccHPMDA-FFDA, T400 = 84.6%). In theory, the existence of the highly electronegative –CF3 groups efficiently reduced the charge transfer (CT) actions from the electron-donating diamine units to the electron-withdrawing dianhydride units, resulting in the prohibition of visible light absorption by the polymers. Meanwhile, the non-conjugated cyclohexane rings also caused a reduction in the CT effects. The CT interactions could be explained by calculating the frontier molecular orbital (MO) energies of the CPIs, as shown in Figure 15. The calculated εHOMO, εLUMO, and energy gap (Δε, |εHOMO − εLUMO|) values are shown in Figure 16. In the literature, both experimental and theoretical investigations of the PI films have proven that intra- and intermolecular CT with diamine to dianhydride moiety can play an important role in determining the ultraviolet absorption of PI films [37,38]. The Δε values of the CPI films could be used to roughly reflect the difficulties related to CT interactions within the molecular chains of the PIs. The larger this value is, the more difficult it will be for it to cause CT interactions. The Δε values of the CPI films increased in the order of CPI-Ia (4.83 eV) < CPI-IIa (4.85 eV) < CPI-ref1 (5.39 eV) = CPI − ref2 (5.39 eV).

Optical Properties\"], \"source_text\": \"Lastly, the refractive indices (nTE and nTM), birefringence, and optical retardations of the CPI films were tested, and the results are tabulated in Table 4. It is well known that the refractive index of a polymer film is dependent on the sum of the molar refraction (P) to the molar volume (V) of each group in its molecular structure, according to the Lorentz–Lorenz equation [39]. The lower the P/V value, the lower the refractive index of the polymer film, and vice versa. The specific values of the P and V parameters of common substituents have been established in the literature via experimental or calculation methods [40]. Fluorine-containing groups are usually listed among the low-P substituents, while fluorene-containing groups are listed among the high-P and high-V components [41]. These structural features explain the lower refractive indices of the current 6FODA-based CPI films compared with those of the fluorene-based ones. For the CPI films based on ccHPMDA, the nav values increased in the order of CPI-ref1 (ccHPMDA-6FODA, 1.5407) < CPI-Ib (ccHPMDA-FFDA, 1.6094) < CPI-Ia (ccHPMDA-FDA, 1.6296). The ctHPMDA-derived CPI film showed a similar trend. The fluorinated 6FODA-PI and FFDA-PI films showed lower nav values than those of the non-fluorinated FDA-PI films due to the low molar refraction of the fluorine-containing groups (–F or –CF3). The fluorene-containing CPI films show very low birefringence (Δn) values at the level of minus fourth power of ten, and further, exhibit quite low optical retardations below 10 nm. The Rth values for the current fluorene-based CPI films (thickness: 10 μm) were obviously lower than those of the CPI systems reported in the literature, such as the wholly aromatic ones in [42] (Rth: 114~172 nm, measured with a film thickness of 2 μm), the ones in [43] (Rth: 84.5~135 nm, measured with a film thickness of 20 ± 5 μm), and the ones in [21] (Rth: 42~279 nm, measured with a film thickness of 15~18 μm), and were also lower than those of the semi-alicyclic ones in [44] (Rth: 276~496 nm, measured with a film thickness of 10 μm). The excellent optical properties of the current CPI films benefited partly from the fluorene substituents in the diamine units, and also from the cyclohexane structure in the dianhydride moiety. On one hand, the bulky fluorene groups efficiently prohibited the folding of the molecular chains in one direction in the CPIs, providing the low optical anisotropies of the polymers [45]. On the other hand, the non-conjugated cyclohexane rings in the dianhydride units increased the molecular chain mobility and decreased the chain packing density, resulting in the low Δn values of the CPI films. This also explains the low Rth feature of CPI-ref1 and CPI-ref2, although they showed slightly higher Rth values than those of their fluorene-based counterparts.\", \"title\": \"Design, Synthesis and Properties of Semi-Alicyclic Colorless and Transparent Polyimide Films with High Glass Transition Temperatures and Low Retardation for Potential Applications in Flexible Electronics\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "76185a383bf39fc123e67b50737de2a6add5707c2d8cfcbc5a41034454d277bd"}

Generally, in our work, an absolute viscosity around 1.0 × 104 mPa·s for the CPI solution was used for the spin-coating fabrication of the CPI films in order to achieve a suitable film thickness at a specific spinning rate. As shown in Figure 7, to achieve this viscosity, the CPI solutions possessed increasing solid contents in the order of CPI-IIa < CPI-IIb < CPI-Ia < CPI-Ib. This sequence is basically the opposite of the order of the Mn values of the resins. According to the results, different solid contents were chosen for CPI solution preparation.

However, OLED typically use thin-film transistors (TFT) as the driver circuitry to provide the power supply to EL devices. The type of polymer used is limited by the relatively high temperatures used in the process.

One of them is friction-greening, which is triggered by prolonged use of mobile phones. It is a key concern of consumers and mobile phone producers because the human eye is extremely sensitive to the green [6]. Many manufacturers have triggered related debates and experienced huge financial losses. As a result, many efforts have been made to address this issue. For example, electrostatic liquid [7] and shield layers [8] have been adopted to improve the performance of friction-greening. However, these methods have a side effect on the capacity or costs. More research has shown that this problem can be traced back to two main causes. One is the high efficiency of green pixels in OLED, typically 200 cd/m2 for green, corresponding to 150 and 10 cd/m2 for red and blue [9,10]. Slight current changes lead to a significant increase in the percentage of green in white light. The other is the threshold voltage (Vth) drift of TFT [11]. A large amount of electrical charge is generated due to the constant friction between a finger and a screen, which conducts downwards and gathers in PI as a back gate. This results in a positive drift of the Vth with an increase in output current. Reducing the efficiency of emitters seems impractical for OLED, so it would be more cost-effective to study the association between PI and friction-greening in more depth.\", \"title\": \"Unveiling the Mechanics Behind Polyimide’s Friction-Greening Phenomenon\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "fd2004b4ed5d6a486a157edfe8763257eba70c4e0af3bcdbebe958c7b810c86d"}

More importantly, segments of the amorphous region shrank within the PI as the temperature increased, resulting in a more regular structure and enhanced intramolecular charge transfer (CTC), which was confirmed by X-ray small angle scattering (SAXS) and photoluminescence. Alternating current (AC) conductivity and trapping properties of PI also benefitted from these changes. As a result, the charge that accumulated in the PI could be reduced, and the Vth shift reduced from 1.12 V to 0.36 V when the temperature increased from 350 °C to 470 °C.

As shown in Figure 1A and Figure S2, the maximum rate of weight loss was found to be at 130 °C, corresponding to the release of free NMP and the substantial evaporation of product water. The peak at 260 °C was the evaporation of bonded NMP [12,13]. A small peak at 348 °C could be found in the DTGA curve of PAA, indicating that there were still residual functional groups undergoing imidization reaction. This also confirmed that in the TGA-MS spectrum trace amounts of moisture could still be observed at this temperature. Considering the outgassing during subsequent TFT processes and the temperature limitations of the equipment, 350 °C and 470 °C were chosen as control groups, while 450 °C was currently the commonly used process temperature. To make the reaction complete, samples were kept for sufficient time, and this could be confirmed by the FTIR spectrum (Figure 1B). Additionally, 1380, 1720, and 1780 cm−1 should be assigned to the stretching of C-N-C, the symmetric and asymmetric stretching of C=O bonds in the imide rings. Their disappearance at 1710 and 1660 cm−1, which were typical absorption peaks of -COOH and -CONH- in PAA, indicated that PAA was almost converted to PI [14]. Because the C=C bond of benzene, 1510 cm−1, would not be affected by the imidization reaction, it could be used as the internal standard with the C-N-C peak area to calculate the degree of imidization of the three samples. Results showed that differences between samples were negligible and even lower process temperatures could ensure the reaction completely (Table 1). Therefore, the thermal stability of the material was guaranteed (Figure S3). The decomposition starting temperature (1% weightlessness) of all samples was greater than 500 °C. The elemental composition and surface roughness were also confirmed by XPS and AFM (Figures S4 and S5). Among the three samples, there was little difference in valence, content, and roughness.

As the segments in sample 350 were relatively loosely spaced, they were more susceptible to orientation, and therefore had the highest dielectric constants. Sample 470 was also larger owing to a higher degree of crystallinity with a certain degree of orientation or higher polarizability due to CTC [22,23].

As shown in Figure 3C, sample 470 had the strongest fluorescence intensity due to its more compact structure, with strengthened CTC. Correspondingly, the absorbance of sample 470 in the visible region was slightly reduced (Figure S8). Defects within materials were further studied by fluorescence lifetime techniques (Figure 3D and Table 3). There were two main types of traps within the PI: deep traps, caused by the chemical structure, such as the absence of the H atom in the imide ring, and shallow traps caused by the physical structure [27]. Data showed that traps in the three samples were mostly shallow, because deep traps usually lead to the quenching of fluorescence. This agreed with SAXS data. In detail, three samples could be fitted with the binary index, I = A1exp(-t/τ1) + A2exp(-t/τ2), where τ1 denotes the intrinsic luminescence property of PI, with no significant difference between three samples, and τ2 denotes the defect-related composite properties, with longer lifetimes indicating deeper trap energy levels [28,29]. Trap energy levels were deepest for sample 350 and shallowest for sample 470, and the number of defects was highest for sample 470. For shallow traps, potential barriers that the charge needed to overcome during jumping would be smaller, which reduced the density of space charge accumulation in PI [30]. For polymers with a two-phase structure, in the crystalline region the charge could easily migrate in the main chain, so it was also easier to achieve electron hopping between neighboring molecular chains due to the lower potential barriers of electrons. But it was different in the amorphous region, because of the existence of impurities and chain breakage, traps were deeper and potential barriers were higher. Therefore, it was easy to cause the build-up of the charge, resulting in the accumulation of the charge [31]. At the same time, more shallow traps can have a shielding effect on the external electric field and reduce charge injection [32].

Sample 350 expressed as a broad peak with no clear peaks, indicating that poly-dispersion in a long period (crystalline + amorphous regions) was present in it. Sample 450 and sample 470 exhibited a peak that gradually shifted to the higher vector, suggesting that the periodicity became shorter as the temperature increased [20].

Among various polymeric materials, polyimide (PI) has emerged as a prominent candidate for high-temperature energy storage dielectric applications due to its exceptional combination of mechanical strength, electrical insulation properties, and thermal stability [4,6]. Recent advancements in nanocomposite technology have demonstrated that the incorporation of nanoscale fillers into polymer matrices can substantially enhance energy storage performance [4,7,8]. However, precise control over the microstructural characteristics of fillers, including their dimensional parameters, morphological features, dispersion homogeneity, and void defect distribution, remains a significant technical challenge [9]. Furthermore, the inherent dielectric mismatch between the constituent phases induces electric field redistribution and facilitates charge injection at the electrode interface, which consequently deteriorates the breakdown strength of the composite system and ultimately compromises its energy storage capabilities [10,11,12]. These fundamental limitations pose substantial barriers to the industrial-scale production and practical implementation of nonlinear polymers incorporating multidimensional fillers [13,14,15,16,17,18]. Consequently, there exists a critical need to develop innovative, cost-effective, and scalable fabrication methodologies that can effectively mitigate both electrode charge injection and bulk carrier transport in dielectric polymers, particularly for demanding high-temperature applications [19].\", \"title\": \"Polyimide Modified with Different Types and Contents of Polar/Nonpolar Groups: Synthesis, Structure, and Dielectric Properties\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "2973f5c36cfefc12b35a223861d91a96dc3ae03998f5d32c052b028fc8f00083"}

The heterogeneous interface formed between the constituent polymers facilitates interfacial polarization through the suppression of premature polarization saturation. Furthermore, the interpenetrating network morphology significantly reduces charge carrier density within the polymer matrix, thereby minimizing void defect formation. This unique structural characteristic contributes to substantial improvement in dielectric breakdown strength (Eb), making it a promising approach for developing high-performance energy storage (Ue) materials. Ahmad et al. [24] filled poly (arylether urea) (PEEU) into a PI matrix, which showed a maximum Ue of 5.14 J/cm3 with Eb~495.65 MV/m at room temperature. Wu et al. [18] modified PP (polypropylene) and synthesized a copolymer with flexible hydroxyl (-OH) and polar functional groups (-NH2). When the hydroxyl content was 4.2 mol%, the dielectric constant of the modified PP increased to twice that of BOPP (biaxially oriented polypropylene), while maintaining a linear reversible polarization curve. At 600 MV/m, Ue was about 7 J/cm3. Xiao et al. [25] used random copolymerization to prepare PI separation membrane materials. The results showed that after copolymerization, a mesh-like structure formed between the polymer chains, and extended conjugated aromatic structures were generated between the units arranged within the polymer backbone, effectively increasing the internal cross-linking density of the polymer. The strategic design of molecular networks through precise engineering approaches has enabled the simultaneous optimization of mechanical strength and toughness, facilitating the development of advanced materials with tunable mechanical properties. Recent investigations employing ionic or crystalline domain cross-linking methodologies have successfully fabricated densely interconnected molecular architectures [26,27]. These sophisticated structures endow materials with precisely controllable mechanical characteristics, including an adjustable tensile strength and elastic modulus, while significantly expanding their potential applications across various engineering fields. The implementation of such cross-linking strategies has demonstrated remarkable potential in overcoming the traditional strength–toughness trade-off, thereby opening new avenues for the development of multifunctional materials with tailored mechanical performance.\", \"title\": \"Polyimide Modified with Different Types and Contents of Polar/Nonpolar Groups: Synthesis, Structure, and Dielectric Properties\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "6bfd8c7a6b0a25a8ae192847d0136fa1a454ef5c68052e600c963114cbb50c5d"}

The selected diamine monomers were specifically chosen to incorporate contrasting functional moieties: one containing a bulky trifluoromethyl (-CF3) group to introduce steric hindrance effects, and the other featuring a polar ether linkage (C-O-C) to enhance molecular interactions. The molar ratios of these diamine monomers were precisely adjusted according to a predetermined protocol while maintaining a stoichiometric balance between the total diamine and dianhydride monomers throughout the polymerization process. Remarkably, the introduction of a highly dipolar rigid backbone enabled the copolymerized PI to maintain excellent thermal and mechanical properties while enhancing dipole polarization. Thus, the dielectric constant was 4.2 with a loss of less than 0.008, at 1000 Hz. Bulky side groups were incorporated, acting as deep traps to capture and disperse charges during the charge transfer process, thereby improving the breakdown strength of the polymer. At room temperature, the energy storage density and charge–discharge efficiency were 5.07 J/cm3 and 82%, respectively. Importantly, based on DFT (density functional theory) calculations, a more significant structure with the best micro-electron structure and properties was shown, which related to energy levels and nearby functions. It was speculated that the copolymerization ratio of PI-60% was the most stable and exhibited the best overall performance, which perfectly matched the experimental results.

The dipole moments of the introduced C=O and C-O-C groups in the BABP monomer are 8.02 μ/10–30 C.m and 2.87 μ/10–30 C.m, respectively [38].

The developed random copolymerization methodology enables the effective integration of complementary characteristics from two distinct diamine monomers, resulting in the synergistic enhancement of dielectric properties. Under the optimal ratio (PI-60%), the copolymer exhibits high Tg (263 °C), high tensile strength (120 MPa), high εr (4.2), high Eb (493 MV/m), and low tanδ (≤0.008). Ultimately, Ue and η are 5.07 J/cm3 and 82%, respectively. Furthermore, based on DFT calculations, the copolymerization tendencies of the PI films were verified by electrostatic distribution simulations, calculations related to energy levels and nearby functions, and UV-vis-NIR. It was confirmed that the PI with a PI-60% copolymerization ratio is the most stable and exhibits the best overall performance, aligning perfectly with the experimental results.

All chemicals were procured from Sigma-Aldrich, Victoria, Australia and zinc oxide was obtained from Fluka Analytical, Victoria, Australia with all reagents used in their original form. A two-step fabrication process was implemented to overcome solubility concerns associated with polyimide (Figure 1). First, individual metal oxides or graphene nanoplatelets, or a mixture (1:1) of metal oxide/graphene were suspended in 15 mL DMC with the view to achieve the final particle concentration of 0.75 wt% (final weight of additives) in the final composite. Separately, 1 g of ODA and 1.08 g of PMDA were dissolved in 15 mL of N,N-dimethylacetamide (DMAc) to produce poly(amicacid). Then, the nanoparticle suspension was mixed with poly(amicacid) using a magnetic mechanical mixer (Thermo Scientific Cimarec S88854100 Stirrer, Marietta, OH, USA) with a heating function. The two-stage mixing was performed to mitigate the high viscosity of the poly(amicacid)/dimethyl carbonate solution, ensuring optimal particle dispersion quality. The mixture was heated to 65 °C, with a rotation speed set at 6rpm, and the mixing duration was 15 min. The mixture was then poured into aluminum molds and kept in an oven at 60 °C for 24 h. Once the composite films formed, the molds were removed from the oven and allowed to cool under ambient conditions, at which point the films (average thickness ≈ 1 mm) were stored for further testing inside the mold.

In the region of low Earth orbit (LEO), through which spacecraft and satellites navigate, atomic oxygen dominates the environmental composition, comprising 80% of the atmosphere, with nitrogen molecules representing only 20% [3]. At altitudes of 300–500 km under ultravacuum conditions of 5 × 10−10 Torr, the short-length (100−200 nm) UV radiation of 10−6 W/m2 triggers photo-dissociation of O2 molecules into atomic oxygen (AO) with a flux of 1013−1015 AO/(cm2·s) [4,5], where the mean free path is sufficiently long that the probability of recombination and formation of ozone is insignificant [5]. The kinetic energy from AO collisions with spacecraft surfaces is sufficiently intense to break chemical bonds between atoms, following which the remaining AO atoms bond with free surface atoms and oxidize the surface [6,7]. The collision energy could be up to ~4.5−5 eV/atom or higher because of the velocity of spacecraft travelling through the atmosphere (~8 km/s), also influenced by the angle between the spacecraft and incident AO, the orbital altitude of the satellite and the intensity of solar activity [3]. These interactions negatively impact the material in a number of ways [8]. The scission of chemical bonds [9] results in the development of structural defects and mass loss, contributing to mechanical failure, whereas the evolution of surface morphology rich in standing cones [9] may degrade the performance of optical and thermal control materials.\", \"title\": \"Polyimide Reinforced with Graphene/Metal Oxide Nanocomposites: Surface Degradation Study Under Atomic Oxygen\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "c597d0e5c5cc4721eba8e648cd302d1c6f33cce659df1d569de6e6735c3b58b8"}

Among promising nanofillers, graphene is recognized for its high strength, flexibility, and electrical conductivity [26,27]. Moreover, its distinctive one-atom-thick carbon lattice structure acts as an effective shield, limiting the penetration of atomic oxygen and thus reducing the oxidation rate [28,29]. Previous studies have shown that both few-layer graphene and graphene oxide were able to improve the resistance to AO degradation in polyvinylalcohol, chosen as a model polymer matrix given the prevalence of its use to investigate the effect of graphene-type materials on the properties of the composite [30]. Flakes with a larger lateral size of 1.3 μm2 were found to be more effective than smaller (∼0.23 μm2) flakes, reducing the mass loss by 42% at a filler concentration of 1 wt%. A comparable reduction in the AO erosion-induced mass loss of ~60% was also reported for cellulose acetate films reinforced by 1 wt% graphene flakes with a size of ~2 μm2 [31]. The reduction was attributed to shielding of the underlying polymer by graphene flakes that were driven during composite preparation to align parallel to the film surface by the combined effects of surface tension of the solution, the two-dimensional structure of the flake itself, and gravitational forces. Furthermore, a ~12% increase in the tensile strength and ~15% increase in Young’s modulus was reported, attributed to the interlocking of graphene with polymer chains and increased cross-linking. Films containing 0.25 wt% showed an even higher improvement in the tensile strength of 16% compared to pure polymer, suggesting that agglomeration and restacking of flakes at higher concentrations may impede bonding between the inorganic and organic phases.\", \"title\": \"Polyimide Reinforced with Graphene/Metal Oxide Nanocomposites: Surface Degradation Study Under Atomic Oxygen\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "6a824a4de3f56fef90949b294e53a012a85c084f81942e68309e2f944a79cea5"}

Earlier NASA reports also emphasize the critical role of oxide passivation layers, noting that oxides such as TiO2 provide durable protection when continuous and defect-free; however, these are sensitive to coating defects and interfacial instability [39,52]. The PI+G+TiO2 composites showed an increase in roughness of ~20%. Similar to the PI+G+ZrO2 composites, this adverse effect can be due to filler incompatibility and poor dispersion (Figures S1 and S2).

This might be due to the formation of stable, protective layers that resist AO-induced surface degradation and prevent pit or spike formation. The presence of a high peak (Sp = 1.05 µm) in the PI+TiO2 sample means that, while titanium dioxide forms a dense, AO-resistant surface lowering the overall roughening and prevents sharp valleys or spikes, some isolated tall features may persist, likely due to localized imperfections or incomplete coverage, though the overall surface is much flatter and more stable than unprotected PI.

Although graphene smooths the overall surface, the maximum peak height remains higher than in control PI, most likely due to agglomerates or poorly dispersed flakes protruding above the matrix.

With the introduction of 0.25 wt% graphene, the composites showed a notable reduction in surface roughness values after AO exposure when compared to control, at Sa of 67.8 nm and Ra of 65.5 nm, which was consistent with the SEM observations of a denser and more uniform surface. This improvement is due to presence of well-dispersed graphene nanosheets, which act as impermeable barriers to AO and dissipate localized bombardment energy. At 0.5 wt% graphene, the surfaces of exposed composites showed a slightly higher roughness (Sa = 76.9 nm, Ra = 83.2 nm) when compared to PI+0.25G; however, both parameters were still significantly lower than that of the control PI.

A general increase in intensity is indicative of strong molecular interactions, most likely π–π stacking between the aromatic rings of polyimide and the graphene sheets, which caused a more ordered structure or an alteration in the dipole moment of the functional groups and enhanced their infrared activity. Most imide and aromatic peaks, such as those assigned to C–N–C and C=C vibrations, respectively, appear with decreased intensities (↓) in PI treated with AO, reflecting oxidative degradation of the imide structure and partial ring opening.

Since one of the uses of AO-resistant coatings is in astronaut extravehicular mobility units (EMUs) or space suit components during on-orbit repair works in LEO [73], it is important to assess how graphene-reinforced polyimide coatings behave when applied to structural fabrics such as woven fiberglass cloth. Fiberglass is widely used as a reinforcing textile in aerospace due to its high strength-to-weight ratio, thermal stability, and dimensional integrity [74]. However, its surface can be brittle and susceptible to erosion or cracking under harsh environments [75]. By dip-coating rectangular woven fiberglass specimens with poly(amicacid) solutions containing 0%, 0.25%, 0.5%, and 0.75% graphene, followed by solvent evaporation and thermal imidization, a uniform PI+G composite layer was formed that infiltrated the fabric microstructure. These coated substrates were then subjected to mechanical testing to determine whether the improvements in AO erosion resistance observed in free-standing films translate into reinforced composites, and to assess any trade-offs between enhanced AO durability and mechanical strength retention. This step was particularly important since increasing graphene content, while beneficial for AO resistance, can sometimes compromise strength due to filler agglomeration [44] or reduced matrix cohesion. Moreover, the Sp values in Table 3 also showed the formation of tall peaks, for higher concentration of graphene, which may correspond to poor dispersion or particle agglomeration. Therefore, the woven cloth testing provides a critical bridge between laboratory film characterization and potential application in astronaut protective systems or aerospace structural laminates.\", \"title\": \"Polyimide Reinforced with Graphene/Metal Oxide Nanocomposites: Surface Degradation Study Under Atomic Oxygen\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "4cedcce6a1682113dc1d30abd33590e0089440f58ddfcd777e2d937b46424e58"}

They have been widely used in the advancement of technologies in many fields, such as automotive, aerospace, sport and safety equipment, and electronics. However, the fabrication of aromatic polyamides and polyimides, through the melt or the solution processing, is generally difficult because they have high softening or melting temperatures and are insoluble in most organic solvents. Fabrication of aramid fibers was generally carried out from anisotropic solutions in strong acids, such as concentrated sulfuric acid or in polar organic solvents containing dissolved inorganic salts. Although aromatic polyimides can be processed through a two-step process based on soluble poly(amic acid) precursors, this common technique still retains some inherent problems, such as instability of poly(amic acid)s and release of water during thermal curing. Solubility improvements of aromatic polyamides and polyimides could be achieved by macromolecular engineering, mainly by designing and synthesizing new monomers [3,9,10]. Moreover, most aromatic polyimide films usually exhibit deep color due to charge transfer complexing (CTC) [11,12]. Organosoluble and colorless aromatic polyimides could be obtained from the monomer combination of less electron-accepting bis(ether anhydride)s and less electron-donating trifluoromethyl-substituted diamines [13,14]. The use of aliphatic dianhydride and/or diamine monomers also could decrease the CTC effect and led to low color or colorless polyimides [15,16].\", \"title\": \"Synthesis and Electrochromism of Highly Organosoluble Polyamides and Polyimides with Bulky Trityl-Substituted Triphenylamine Units\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "b8b795569b4cb86d1baa93827e64ac17de7e50d0e5b3888cc0fcae04155b2b9a"}

For example, Zhang et al. introduced a non-polar bulky triphenylmethyl (trityl) pendent group onto polyimides, which exhibited a high solubility and low dielectric constant [40]. Aromatic polyimides and polyamides with double propeller-shaped trityl-substituted triphenylamine units have been reported by Zhang’s group [41] and Banerjee’s group [42], respectively. The obtained polyimides and polyamides exhibited good solubility in many aprotic solvents and had moderate to high glass transition temperatures. Moreover, the incorporation of bulky trityl-substituted triphenylamine units increases the interchain spacing and reduces the packing efficiency, thereby increasing the intrinsic microporosity. Thus, they also exhibited a good gas separation performance. Although the gas transport properties of polyimides and polyamides bearing trityl-substituted triphenylamine units have been reported, little information was known for their electrochemical and electrochromic properties. As a continuation of our devotion to research and developments in easily processable high performance polymers with electrochromic function, herein we synthesized and characterized some aromatic and semi-aromatic polyamides and polyimides containing trityl-substituted triphenylamine units, and the electrochemistry, spectroscopy, and electrochromic cycling stability of the polymer films were also investigated. In addition to increased solubility caused by the incorporation of twisted nonplanar trityl substituent and triphenylamine group, the increased free volume was expected to allow better charge transfer at doping, and thus leading to fast switch speeds.\", \"title\": \"Synthesis and Electrochromism of Highly Organosoluble Polyamides and Polyimides with Bulky Trityl-Substituted Triphenylamine Units\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "6eda7e33276b8cb9a775219b3eae19c0717cfe017177fe2bfdcdb1402e1816c1"}

The CV diagram of 5e/HV is depicted in Figure 11b, demonstrating reversible redox steps with a decreased oxidative potential (Epa at 1.2 V). This effect could be ascribed to HV2+ having the capability to accept electrons from TPA moieties during the oxidation process, and then the resulted HV+ also could donate electrons back to TPA radical cations during the reducing process. The spectroelectrochemical graphs of 5e ECD are presented in Figure 11c. The spectra and color changes are similar to those observed in the electrochemical cell. Spectroelectrochemical behavior of ECDs 5e/HV was also studied and depicted in Figure 8d. New absorption peaks could be observed at 366 nm and 627 nm due to the reductive process of HV+2 to HV+. Because of the combination of TPA oxidation and HV reduction at the same time, the dual ECD revealed a deeper blue coloring as the potential was applied.

These systems have highly linear backbone structures without exception. The low-CTE values of these PI films are associated with the highly aligned PI main chains in the X–Y direction (a high degree of in-plane chain orientation), which occurs during the thermal imidization of the PAA cast films formed (fixed) on a substrate [40,41]. Furthermore, the extent of in-plane orientation, which is closely related to the thickness-direction birefringence (∆nth = nxy − nz), strongly depends on the overall backbone linearity/rigidity of the PIs [42,43,44,45,46,47,48,49]. Therefore, for obtaining a low CTE, it is necessary to choose monomers with linear/rigid structures both in the tetracarboxylic dianhydrides and diamines. Drawn two-dimensionally, the repeating units of the 6FDA/TFMB system also seem to have a relatively linear structure, as shown in Figure 5. However, it is most likely that the 6FDA-based diimide (6FDI) units have no coplanarity; the phthalimide units of 6FDI are sterically twisted each other at a “hinge” portion (the hexafluoroisopropylidene linkage) [25,26]; thus, the PI main chains lose their overall linearity. Indeed, the thermally imidized 6FDA/TFMB film does not have a low CTE [15,27] (Table 1, sample 2). The situation is similar in the systems using s-ODPA and 3,3′4,4′-biphenylsulfonetetracarboxylic dianhydride (DSDA), which contain a hinge structure. A cast film from a PI solution for 6FDA/TFMB does not have a low CTE either, which is a normal phenomenon, as often observed in common polymer systems. This reflects the fact that the simple casting process using PI solutions usually does not have sufficient driving force to result in a high level of in-plane chain orientation.\", \"title\": \"Development of Solution-Processable, Optically Transparent Polyimides with Ultra-Low Linear Coefficients of Thermal Expansion\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "e6a6e825d21ece600acd42bcc95b757b1d5de09e612f7de2160a149ddf88cfc8"}

In addition, it is highly possible that the s-BPDA/TFMB system results in low-CTE characteristics, as expected from its relatively linear chain structure (Figure 6). In this regard, s-BPDA/TFMB is a very limited system that has the potential to simultaneously achieve relatively high transparency and low CTE among the aromatic PI systems obtained from the commercially available monomers. However, the thermally imidized film had a CTE (34 ppm·K−1 [45,46]) (Table 1, sample 3) that is higher than expected, although it is most likely possible to further decrease the CTE by optimizing the film preparation conditions.

PI films formed on substrates through thermal imidization or solution casting usually accumulate residual strain at room temperature, even after they are peeled away from the substrates. This trend is more prominently observed in less thermoplastic PI systems with rigid chain structures. Before the CTE evaluation by thermomechanical analysis (TMA), the residual stress must be completely removed by annealing the films in a free state above the used imidization temperature (or final heating temperature) for less thermoplastic systems. On the other hand, for thermoplastic systems, the annealing is carried out just below the Tg to avoid significant film deformation (at a 10–20 °C lower temperature than the Tg). If this pre-treatment is skipped, the specimens often undergo irreversible contraction accompanied by the release of the residual strain in the course of heating for the CTE measurements. Consequently, the TMA curve is deformed. The proper TMA curves usually consist of two straight lines with a small slope in the glassy region and an abruptly increased slope above the Tg. The above-mentioned film contraction behavior often causes an “underestimation” of the magnitudes of CTE. In principle, the TMA curve in the glassy region is completely reversible between the heating and cooling processes [50]. Thus, the reversibility is direct evidence for the correctness of the CTE values.

A cardo-type tetracarboxylic dianhydride (TA-BPFL, Figure 10) possessing a bulky fluorenyl side group is also useful in preventing the formation of a tight salt [64]. Incidentally, the molecular bulkiness of TA-BPFL also contributes to the excellent solubility of the resultant PIs; surprisingly, the thermally imidized TA-BPFL/t-CHDA film maintains excellent solubility in contrast to the fact that t-CHDA-derived PIs are usually quite insoluble in common organic solvents [64]. Method (c) also sometimes contributes to the rapid dissolution of the salt by optimizing the reaction conditions [the monomer content, the type of solvents, and reaction temperature]. An unusual monomer feeding procedure (the addition of diamine to tetracarboxylic dianhydride solutions [65]) is also a possible method, although it is not always effective in accelerating the salt dissolution.

Thus, at present, s-BPDA/t-CHDA seems to be the most practically valuable system of the t-CHDA-derived PIs in terms of its simple manufacturing processes and the excellent properties mentioned above. However, there is still room for improvement in the film ductility because this PI film was somewhat brittle (the maximum elongation at break in the tensile test, εb max, was about 10%). This is probably inevitable because of the predicted poor chain entanglement arising from its linear/stiff chain structure. Our attempts extend to improving the film ductility while maintaining the very low CTE. Copolymerization with flexible monomers is often effective in improving the film ductility of s-BPDA/t-CHDA. However, the CTE of the copolymers inevitably increases with increasing flexible comonomer contents (our unpublished results). Thus, it is very difficult to escape from this “additivity rule” between the CTE and the copolymer composition. Similarly, s-BPDA/t-CHDA can be modified by sequence-controlled copolymerization with a flexible cycloaliphatic diamine (NBDA, Figure 8), accompanied by an increase in the CTE with increasing NBDA content [68].\", \"title\": \"Development of Solution-Processable, Optically Transparent Polyimides with Ultra-Low Linear Coefficients of Thermal Expansion\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "b093c4d965fa8597d6fa4a88e4625cd355d16d8e0b8daff06a183555ef937922"}

In addition, the ease of ring opening (in other words, the ease of PAA formation) by strain release suggests difficulty in the ring closure (i.e., imidization). Indeed, in our experience, to complete imidization, the CBDA-based systems require heating at higher temperatures than in other systems (e.g., H-PMDA-based systems). This is an undesirable situation for suppression of film coloration. Therefore, if possible, it is preferable to prepare the CBDA-based PI films through the casting of the PI solutions without the high-temperature thermal imidization process.

For example, the CBDA/TFMB system led to a colorless PI film with a relatively low CTE (21 ppm·K−1). However, this PI system is insoluble in common organic solvents (i.e., the absence of solution-processability and the chemical imidization process compatibility) and led to a somewhat brittle film (εb < 10%).\", \"title\": \"Development of Solution-Processable, Optically Transparent Polyimides with Ultra-Low Linear Coefficients of Thermal Expansion\"}"}], "tools": [], "split": "test", "tools_supplied_in_common_system": true, "tools_native_template_argument": null, "max_new_tokens": 2048, "structured_history_records": [], "semantic_messages_sha256": "6d2cbe441745808a2dba8c344435b1335a772d639fb6af63f4a0c7fe1bf428dc"}

In particular, the TA-HQ/TFMB system (Table 1, sample 14) leads to a film with suppressed coloration like that of the s-BPDA/TFMB film. These results motivated us to evaluate whether TA-HQ and its analogs have the potential for achieving our targets. Thus, the substituent effects were examined by varying the type and the number of substituents introduced to the HQ unit (methyl, methoxy, tert-butyl, amyl, and norbornane groups). Among the substituents examined, the 2,3,5-trimethyl, 2,5-di-tert-butyl, and 2,5-diamyl substituents (bottom right in Figure 7) are very effective in improving the solubility [21]. These PEsI systems offer highly transparent films through chemical imidization. In particular, the CPN-cast film for the system derived 2,3,5-trimethyl-substituted TA-HQ (i.e., TA-TMHQ) and TFMB (Table 1, sample 15) achieves excellent combined properties: a very low CTE (12 ppm·K−1), relatively high transparency (T400 = 65%), a relatively high Tg (276 °C by TMA), a very low water uptake (0.13%), and sufficient film ductility (εb max = 27%).
