the monitoring of the imidization reaction of polyimides. 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.

Thermal treatment at 200°C for 30 min resulted in medium-imidized pristine and additive-doped samples. Using IR spectroscopy, imidization degrees of 50 ± 1% (for pristine polyimide, n = 4), 50 ± 6% (for butylated hydroxytoluene addition, n = 4), and 43 ± 3% (for 2,4-dibromophenol addition, n = 4) were received.

This effect was already apparent when comparing IR and LIBS results during method development and can be expected since different cross-sections regarding penetration/ablation depth and sampling areas are taken into account using the two techniques.

Thermal treatment at 200°C for 30 min resulted in medium-imidized pristine and additive-doped samples. Using IR spectroscopy, imidization degrees of 50 ± 1% (for pristine polyimide, n = 4), 50 ± 6% (for butylated hydroxytoluene addition, n = 4), and 43 ± 3% (for 2,4-dibromophenol addition, n = 4) were received. Analyzing the same samples with LIBS resulted in the following imidization degrees: 44 ± 3% (for pristine polyimide, n = 4), 38 ± 2% (for butylated hydroxytoluene addition, n = 4), and 38 ± 2% (for 2,4-dibromophenol addition, n = 4). These results show that the calculations and results within one technique are consistent, and no influence of additives on the performance of the established IR as well as the proposed LIBS method was detected although the results of each analysis method differ ((IR, 50 ± 0.6%, and LIBS, 44 ± 3% for the pristine sample cured at 200°C for 30 min). This effect was already apparent when comparing IR and LIBS results during method development and can be expected since different cross-sections regarding penetration/ablation depth and sampling areas are taken into account using the two techniques.

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. When Tc increases, a general increase of all the imide absorption peaks is observed, while the band of the aromatic ring stretching (C = C at 1500–1520 cm−1) remains unchanged since it is unaffected by the reaction.Fig. 2Specific wavenumber region from 550 to 2500 cm.−1 (average of 6 scans) of polyimides cured at 400°C for 120 min (PI-400–120-1), 200°C for 30 min (PI-200-030–1), and 160°C for 5

is a state-of-the-art technique to monitor the condensation reaction of polyimides and calculate the imidization degree. IR measurements have been performed for all samples exhibiting different imidization temperatures Tc and imidization times tc. To illustrate the advancement of the imidization reaction, three representative samples including a hardly imidized film (PI-160–005-1), a semi-imidized film (PI-200–030-1), and a completely cured polyimide film (PI-400–120) are shown in Fig. 2. In order to detect the bond changes during the imidization reaction, assignments of the absorption bands are necessary [10, 15, 16]. IR spectra were recorded in the range of 550–4000 cm−1, but all relevant bands can be found between 550 and 2500 cm−1 (Fig. 2). 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.

Especially as coatings, PIs should be insoluble in electrolytes as well as possess good electrolyte wettability. This performance requirement is important for enhancing the electrochemical performance. 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. First, pyromellitic dianhydride (PMDA) and 4,4′-oxydianiline (ODA) are polymerized to obtain PAA at low temperatures. Then, a certain concentration of PAA solution is mixed with cathode active materials to coat the PAA onto the surface of active material particles. Thereafter, the PAA-coated cathode materials are thermally imidized through a step-by-step heating method to convert PAA to PI coatings [35]. Finally, active material particles with PI nano-coatings are obtained.Fig. 2a Schematic of PI coating onto an LNMCO cathode material. b TEM image of PI-coated LiNi1/3Mn1/3Co1/3O2 (PI@NCM333). c

Finally, active material particles with PI nano-coatings are obtained.Fig. 2a Schematic of PI coating onto an LNMCO cathode material. b TEM image of PI-coated LiNi1/3Mn1/3Co1/3O2 (PI@NCM333). c Electrochemical performances of LNMCO, PI@LNMCO-300, and PI@LNMCO-450, including initial efficiency, cycling, and rate capability (300 and 450 represent thermal imidization temperatures). d Schematic of the mechanism for enhanced electrochemical performances in PI-coated NCM333", "title": "Polyimides as Promising Materials for Lithium-Ion Batteries: A Review"}, "source_group": "doi:10.1007/s40820-023-01104-7", "source_text_truncated": false, "split": "test", "source_index_candidate": {"variant": "index_only", "source_only_index_payload_sha256": "a9c4cf25e411ecc2b1e4c15eef39225e32950cdea08f97362c3b3e28a458249f", "boundary_tokens": 202, "source_length_codepoints": 1440, "original_messages_sha256": "ff8a97588dbd4ef2ea357b523ee5d98d5da520fe7cf5177f38a19d466569fbfd", "deterministic_boundary_index_is_additional_input": true, "reference_or_review_used_to_build_prompt": false, "post_generation_repair": false}, "semantic_messages_sha256": "69626e07b9159fe08e65621c22d615281294d84f9ab89221f4afd35ed0ea1b1a"}

with PI active storage materials to prepare electrodes. Much effort is utilizing graphene to synthesize the PI-Graphene electrode materials by the in situ polymerization strategy, which could make full use of the surface area of graphene and possess several magnitudes higher electronic conductivity compared to pure PI polymers. In Fig. 14a, the graphene and two kinds of carbonyl polymers poly(anthraquinonyl) sulfide (PAQS) and polyimide (PI) were blended to prepare graphene/PI nanocomposites by the in situ polymerization method [98]. In Fig. 14b, the monolithic 3D graphene/polyimide composites (GF-PI) were prepared by the one-step solvothermal strategy [114]. In Fig. 14c, Ahmad et al. [115] developed a novel PI-FLEG (few-layer exfoliated graphene) nanocomposite, where PI nano-flakes shorten the diffusion path length between the electrolyte and electrode interfaces, leading to a further increase in the rate capability. In Fig. 14d, NTCDA and 2,6-diamino-anthraquinone (DAQ) as redox-active monomers in the presence of graphene oxide (GO) were in situ polymerized to obtain the graphene-sandwiched PQI nanosheets (PQI@Gr) [116].

It can be seen from the curve that at the electric field of 500 kV cm−1, the maximum polarization reached 1.616 μC cm−2, and the remanent polarization (Pr) remained at a very low value, almost close to zero. A large energy-storage efficiency of about 90% (energy loss = 10%) was achieved in the composite film. P–E curves at higher electric fields (>500 kV cm−1) are not provided due to limitation of instruments. Similar trend was also observed in other composite samples (not shown here). According to the P–E loop, it was evident that the rBT/PI composite film possessed linear dielectric performance. 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. Based on the overall consideration of Eb and εr, a high energy density of 9.7 J cm−3 was achieved at 2628 kV cm−1 in rBT/PI composite filled with 30 wt% rBT particles. The energy density of the rBT/PI composites was enhanced by more than 400% over that of pure PI (1.9 J cm−3 at 3251 kV cm−1). Moreover, the energy density of rBT/PI composites was greater than the energy density of BOPP (1.2 J cm−3 at 6400 kV cm−1).63,64 Therefore, such marked enhancement of energy storage density (Ue) was a result of introducing rBT particles in the polymer matrix to form the corresponding composite films. Moreover, another favorable property of rBT/PI composites was their ultrahigh energy storage efficiency. These results indicate that rBaTiO3 can effectively improve the dielectric constant and energy storage density of PI-based composites.\", \"title\": \"Significantly enhanced dielectric constant and

The energy density of the rBT/PI composites was enhanced by more than 400% over that of pure PI (1.9 J cm−3 at 3251 kV cm−1). Moreover, the energy density of rBT/PI composites was greater than the energy density of BOPP (1.2 J cm−3 at 6400 kV cm−1).63,64 Therefore, such marked enhancement of energy storage density (Ue) was a result of introducing rBT particles in the polymer matrix to form the corresponding composite films. Moreover, another favorable property of rBT/PI composites was their ultrahigh energy storage efficiency. These results indicate that rBaTiO3 can effectively improve the dielectric constant and energy storage density of PI-based composites.", "title": "Significantly enhanced dielectric constant and energy storage properties in polyimide/reduced BaTiO3 composite films with excellent thermal stability"}, "source_group": "doi:10.1039/c8ra10434d", "source_text_truncated": false, "split": "test", "source_index_candidate": {"variant": "index_only", "source_only_index_payload_sha256": "3ad11d32f2e01e7d8cce6952285b5d380a6010151a1dcb206663bdef5552e606", "boundary_tokens": 306, "source_length_codepoints": 1906, "original_messages_sha256": "69c89b9fe13d025b120b0cbd10ac7de777939e7b24a3e29b89b4d68a8fc9307f", "deterministic_boundary_index_is_additional_input": true, "reference_or_review_used_to_build_prompt": false, "post_generation_repair": false}, "semantic_messages_sha256": "c370568d5cc724b4eac247fa79683269ccec9a6fc6b61349f3f328a6c3c3f27e"}

critical roles in the modern information and electronic industry as embedded capacitors and charge-storage devices because they are light weight, multifunction-integrated and

dielectric constant (typically less than 10) impedes their practical applications in capacitors.7 A promising strategy to enhance the dielectric constant of polymer materials is to incorporate ferroelectric materials with high dielectric constant (such as titanium dioxide (TiO2),8,9 BaTiO3,10,11 Pb(Zr,Ti)O3,12,13 BaSrTiO3,14,15 K0.5Na0.5NbO3 (ref. 16 and 17) and CaCu3Ti4O12 (ref. 18 and

polyimides25 and epoxy resins.26 The dielectric constant of ferroelectric/polymer composite system can be improved by a few times compared to the pure polymer when a high content of ferroelectric

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. When the content of rBT increased up to 40 wt%, the dielectric constant reached its maximum of about 33.4 at 1000 kHz, which is considerably higher than that of pure PI (εr = 4.1). Subsequently, the dielectric constant sharply decreased to 23.9 with 50 wt% of rBT content. Correspondingly, the dielectric loss of samples was lower (tg δ < 0.031) when the rBT content was below 30 wt%. It was found that the rBT/PI composite with the loading of 30 wt% was the best candidate (εr = 31.6, tg δ = 0.031@1000 kHz) among all the tested composites.\", \"title\": \"Significantly enhanced

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. When the content of rBT increased up to 40 wt%, the dielectric constant reached its maximum of about 33.4 at 1000 kHz, which is considerably higher than that of pure PI (εr = 4.1). Subsequently, the dielectric constant sharply decreased to 23.9 with 50 wt% of rBT content. Correspondingly, the dielectric loss of samples was lower (tg δ < 0.031) when the rBT content was below 30 wt%.

Therefore, water contact angle and water absorption tests were used, and surface hydrophobicity was characterized by the contact angle of water droplets on PI films surface, which is shown in Figure 7. As the content of NADA monomer increases, the water contact angle of PI-0 increases from 66° to 78° for PI-2. 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%.

HCl was removed from the reaction in the form of pyridine hydrochloride. In the reaction, the aromatic acyl chloride group (–COCl) was likely to react with both of the amine groups (–NH2) and hydroxyl (–OH) groups in the molecular structure of 6FAP.

There is no doubt that for the electrospun nano-porous mats, the effect of porous structure on the dielectric constants is much higher than that of the polymer bulk properties. The solid free-standing fluoro-containing PI or PBO films usually exhibit the Dk values higher than 2.0 at 1 MHz even if high fluoro contents were introduced, such as the PI (6FDA-12FDA) and PI (6FDA-15FDA) shown in Table 3 [16]. Although the high-fluoro-content PIs exhibited similar thermal stability with the current PI and PBOs, the Dk values are much higher than those of the NFMs. In addition, the meta-substituted PIBO-2 should generally exhibit a lower Dk value than that of the para-substituted PIBO-1 due to the increased free volumes of the molecular chains. However, the partial adhesion among the fibers that occurred inside the PIBO-2 mats decreased their porosity, thus increasing the Dk values of the mats.

Mean-Square Displacement\"], \"source_text\": \"As shown in Figure S3, the motion of the chain segment of the PEsI systems increased consistently with the increasing temperature. As an example, using PEsI–(CH3)1 and PEsI–(CF3)1, the MSD plots for the two PEsI systems at 400 and 850 K are illustrated in Figure 5a. 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 Tg of the PEsIs was also identified through the slope change of the MSD curve of the chain segments versus the temperature [35].

As an example, using PEsI–(CH3)1 and PEsI–(CF3)1, the MSD plots for the two PEsI systems at 400 and 850 K are illustrated in Figure 5a. 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.

As an example, using PEsI–(CH3)1 and PEsI–(CF3)1, the MSD plots for the two PEsI systems at 400 and 850 K are illustrated in Figure 5a. 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 Tg of the PEsIs was also identified through the slope change of the MSD curve of the chain segments versus the temperature [35].

Potential energy components, such as EvdW and Etorsion, played significant roles in the glass-transition behavior of the PEsIs, as shown by the plots of the energy components against temperatures ranging from below Tg to above Tg. The –CF3 substituent in the PEsI backbone structure reduced the intra- and intermolecular charge-transfer complexes, keeping their rigid-rod-like backbones intact. It is very inspiring that, by applying MD simulations and DFT calculations, we found a new polymer model (PEsI–(CF3)1) that satisfied both high optical and thermomechanical properties. This work provides a useful approach to the design of transparent, highly temperature-resistant molecular systems for advanced optical applications, when compared with the present fluorine chemistry

Moreover, the peak corresponding to the C=O in -CONH- (1660 cm−1, gray band domain) was hardly observed, indicating that the imidization of the PAA solutions was fully completed [27,28].", "title": "Synthesis of Superheat-Resistant Polyimides with Enhanced Dielectric Constant by Introduction of Cu(ΙΙ)-Coordination"}, "source_group": "doi:10.3390/polym12020442", "source_text_truncated": false, "split": "test", "source_index_candidate": {"variant": "index_only", "source_only_index_payload_sha256": "14533bd5e3fdf149e8caf148cc26d0ae34a9d293bc71b2e2aa3677e926f958fb", "boundary_tokens": 116, "source_length_codepoints": 755, "original_messages_sha256": "661c322c5b90be1ee37e95e0b48e519d4198977e684dc3228c46769cf5042faf", "deterministic_boundary_index_is_additional_input": true, "reference_or_review_used_to_build_prompt": false, "post_generation_repair": false}, "semantic_messages_sha256": "f2fc1b6489d540c4594a882494f175bf5bf8b62f780f52293bb4792697b13976"}

These broad peaks disappeared in the spectra of the membrane after thermal imidization and became sharp peaks. The peaks at 1775 cm−1, 1720 cm−1, 1380 cm−1, and 738 cm−1 correspond to C=O asymmetric stretching, symmetric stretching, CN stretching, and C=O bending, which are primary indications of PI absorption

PAA solution was prepared by reacting with ODA and PMDA, which dissolved in DMAc under dry nitrogen in an industrialized mass reactor overnight. After the polymerization of PAA, the molecular weight was determined by GPC analysis. As shown in Figure S2, the prepared PAA had a molecular weight (Mw) of 231 kDa and a molecular weight distribution of 5.11 (Table S1). With this prepared PAA solution, we fabricated PI layers following the method described in the Materials and Methods section and Scheme 1b. The FTIR measurements were performed to confirm that the PI film was well formed. According to the FTIR spectra in Figure 1, the PAA film showed broad peaks around 1650 cm−1, which indicates the characteristic of amide C=O stretching modes [17]. These broad peaks disappeared in the spectra of the membrane after thermal imidization and became sharp peaks. The peaks at 1775 cm−1, 1720 cm−1, 1380 cm−1, and 738 cm−1 correspond to C=O asymmetric stretching, symmetric stretching, CN stretching, and C=O bending, which are primary indications of PI absorption bands, showing a larger transition with no characteristic PAA peaks [18].", "title": "Mass-Synthesized Solution-Processable Polyimide Gate Dielectrics for Electrically Stable Operating OFETs and Integrated Circuits"}, "source_group": "doi:10.3390/polym13213715", "source_text_truncated": false, "split": "test", "source_index_candidate": {"variant": "index_only", "source_only_index_payload_sha256": "74df1b56229b350f2aeff75307af2d6b7340a3685d009cb64ad141e95e33e66c", "boundary_tokens": 201, "source_length_codepoints": 1249, "original_messages_sha256": "c26b670b2f400d117558bc9ecc7f623c7263342a477788d90c49fe9916af936c", "deterministic_boundary_index_is_additional_input": true, "reference_or_review_used_to_build_prompt": false, "post_generation_repair": false}, "semantic_messages_sha256": "1dc9d180b46b294e35ef99895fd3ca32ef94311d8b619aadc604d0972af48e9f"}

Polyimide (PI), as one of the best insulating organic materials to date, is commonly used in the coating insulation of HFPTs. The gas-solid insulation material inside HFPTs is in the high-frequency electrical stress environment affected by heat and electromagnetic coupling. Therefore, the insulation strength of polyimide is very important. The surface flashover field strength is much less than the air gap breakdown field strength of the same gap, which means that the insulation material is more likely to break down.

Reduced leakage current density may have been due to the large number of deep traps provided by MgO in the nanocomposite, significantly hindering charge migration under high temperatures and electric fields [43].\",\"task\":\"定位给定quote在source_text中的唯一位置；按Unicode码点计数，区间为[start,end)。只输出JSON，保留quote原文。\"}\n以下是仅由同一source_text自动生成的辅助词边界表，每项为[start,end,原文非空白词元]。它覆盖全部非空白词元，不选择证据、不提供科学解释。索引按Unicode码点计算，标记不属于source_text。定位时使用词元的起止位置；跨词引用包含原文空白，text或quote必须逐字保持原文。所有原输出字段和[start,end)合同保持不变，不输出词表本身。\n{\"source_length_codepoints\":1243,\"token_boundaries\":[[0,2,\"To\"],[3,10,\"further\"],[11,18,\"explore\"],[19,22,\"the\"],[23,29,\"effect\"],[30,32,\"of\"],[33,36,\"MgO\"],[37,48,\"nanofillers\"],[49,51,\"on\"],[52,55,\"the\"],[56,65,\"breakdown\"],[66,74,\"strength\"],[75,78,\"and\"],[79,85,\"energy\"],[86,93,\"storage\"],[94,106,\"performance,\"],[107,110,\"the\"],[111,125,\"time-dependent\"],[126,133,\"leakage\"],[134,141,\"current\"],[142,151,\"densities\"],[152,154,\"of\"],[155,157,\"PI\"],[158,163,\"films\"],[164,167,\"and\"],[168,174,\"MgO–PI\"],[175,188,\"nanocomposite\"],[189,194,\"films\"],[195,199,\"were\"],[200,212,\"investigated\"],[213,218,\"under\"],[219,222,\"300\"],[223,225,\"MV\"],[226,230,\"m−1,\"],[231,233,\"as\"],[234,239,\"shown\"],[240,242,\"in\"],[243,249,\"Figure\"],[250,252,\"6.\"],[253,255,\"It\"],[256,259,\"was\"],[260,268,\"observed\"],[269,273,\"that\"],[274,277,\"the\"],[278,285,\"leakage\"],[286,293,\"current\"],[294,301,\"density\"],[302,304,\"of\"],[305,308,\"the\"],[309,315,\"MgO–PI\"],[316,330,\"nanocomposites\"],[331,334,\"was\"],[335,340,\"three\"],[341,347,\"orders\"],[348,350,\"of\"],[351,360,\"magnitude\"],[361,366,\"lower\"],[367,371,\"than\"],[372,376,\"that\"],[377,379,\"of\"],[380,383,\"the\"],[384,388,\"neat\"],[389,392,\"PI;\"],[393,396,\"for\"],[397,405,\"example,\"],[406,410,\"that\"],[411,413,\"of\"],[414,417,\"the\"],[418,420,\"PI\"],[421,424,\"and\"],[425,428,\"0.1\"],[429,433,\"vol%\"],[434,440,\"MgO–PI\"],[441,454,\"nanocomposite\"],[455,460,\"films\"],[461,464,\"was\"],[465,469,\"2.75\"],[470,471,\"×\"],[472,476,\"10−6\"],[477,478,\"A\"],[479,482,\"cm2\"],[483,486,\"and\"],[487,491,\"1.90\"],[492,493,\"×\"],[494,498,\"10−9\"],[499,500,\"A\"],[501,505,\"cm2,\"],[506,519,\"respectively.\"],[520,522,\"As\"],[523,526,\"for\"],[527,530,\"the\"],[531,537,\"MgO–PI\"],[538,552,\"nanocomposites\"],[553,559,\"films,\"],[560,563,\"the\"],[564,571,\"leakage\"],[572,579,\"current\"],[580,587,\"density\"],[588,597,\"increased\"],[598,603,\"first\"],[604,607,\"and\"],[608,612,\"then\"],[613,621,\"declined\"],[622,626,\"with\"],[627,630,\"the\"],[631,639,\"increase\"],[640,642,\"in\"],[643,646,\"MgO\"],[647,655,\"content.\"],[656,658,\"It\"],[659,663,\"must\"],[664,666,\"be\"],[667,679,\"acknowledged\"],[680,684,\"that\"],[685,695,\"electrical\"],[696,706,\"conduction\"],[707,711,\"loss\"],[712,714,\"is\"],[715,718,\"the\"],[719,724,\"major\"],[725,729,\"loss\"],[730,739,\"mechanism\"],[740,742,\"of\"],[743,754,\"dielectrics\"],[755,760,\"under\"],[761,765,\"high\"],[766,773,\"applied\"],[774,781,\"fields,\"],[782,784,\"so\"],[785,790,\"lower\"],[791,798,\"leakage\"],[799,806,\"current\"],[807,814,\"density\"],[815,817,\"of\"],[818,824,\"MgO–PI\"],[825,839,\"nanocomposites\"],[840,842,\"at\"],[843,851,\"elevated\"],[852,864,\"temperatures\"],[865,870,\"means\"],[871,881,\"suppressed\"],[882,892,\"conduction\"],[893,898,\"loss,\"],[899,904,\"which\"],[905,907,\"is\"],[908,918,\"consistent\"],[919,923,\"with\"],[924,927,\"the\"],[928,937,\"variation\"],[938,940,\"in\"],[941,950,\"breakdown\"],[951,959,\"strength\"],[960,965,\"shown\"],[966,968,\"in\"],[969,975,\"Figure\"],[976,977,\"4\"],[978,981,\"and\"],[982,985,\"the\"],[986,996,\"discharged\"],[997,1003,\"energy\"],[1004,1011,\"density\"],[1012,1017,\"shown\"],[1018,1020,\"in\"],[1021,1027,\"Figure\"],[1028,1030,\"5.\"],[1031,1038,\"Reduced\"],[1039,1046,\"leakage\"],[1047,1054,\"current\"],[1055,1062,\"density\"],[1063,1066,\"may\"],[1067,1071,\"have\"],[1072,1076,\"been\"],[1077,1080,\"due\"],[1081,1083,\"to\"],[1084,1087,\"the\"],[1088,1093,\"large\"],[1094,1100,\"number\"],[1101,1103,\"of\"],[1104,1108,\"deep\"],[1109,1114,\"traps\"],[1115,1123,\"provided\"],[1124,1126,\"by\"],[1127,1130,\"MgO\"],[1131,1133,\"in\"],[1134,1137,\"the\"],[1138,1152,\"nanocomposite,\"],[1153,1166,\"significantly\"],[1167,1176,\"hindering\"],[1177,1183,\"charge\"],[1184,1193,\"migration\"],[1194,1199,\"under\"],[1200,1204,\"high\"],[1205,1217,\"temperatures\"],[1218,1221,\"and\"],[1222,1230,\"electric\"],[1231,1237,\"fields\"],[1238,1243,\"[43].\"]]}", "role": "user"}], "origin_content_sha256": "7caaa405879f8fd9a4d4cd579e0454a3f639a39d61c226b1066ef9fcf590302a", "origin_id": "evidence2-e5c614e2a63b1286", "prior_model_answer_in_prompt": false, "source": {"article_type": "research-article", "doi": "10.3390/polym14142918", "locator": "body-p-12", "section": ["3.

Unlike the significantly different absorption peaks seen in the 1H-NMR spectra (Figure 5 and Figure 6) between the ccHPMDA-based and CtHPMDA-based PIs, a difference in absorption peaks due to the stereoisomerism of the structures was not observed in the FTIR spectra. All the polymers showed similar absorptions due to the similar chemical compositions. The similar parts include the characteristic absorptions of imide rings at ~1780 cm−1, ascribed to the asymmetrical carbonyl stretching vibrations, at ~1711 cm−1 due to the symmetrical carbonyl stretching vibrations, at ~1380 cm−1 caused by the C–N stretching vibrations, at 1508 cm−1 due to the stretching vibration of C=C in benzene rings in the diamine units, and at ~2933 cm−1 from the saturated C–H (–CH2–) absorptions in the dianhydride units. The differences mainly relate to the characteristic absorptions at ~1317 cm−1 due to the asymmetrical stretching of C–F bonds in –CF3 groups, and at 1120 cm−1 due to the –O– linkages, which were only detected in the spectra of the CPI-ref1 and CPI-ref2 polymers. In addition, symmetrical C–F stretching vibrations at ~1250 cm−1 were detected in the spectra of both the 6FODA-based CPI films and the FFDA-derived CPI films.

Unlike the significantly different absorption peaks seen in the 1H-NMR spectra (Figure 5 and Figure 6) between the ccHPMDA-based and CtHPMDA-based PIs, a difference in absorption peaks due to the stereoisomerism of the structures was not observed in the FTIR spectra. All the polymers showed similar absorptions due to the similar chemical compositions. The similar parts include the characteristic absorptions of imide rings at ~1780 cm−1, ascribed to the asymmetrical carbonyl stretching vibrations, at ~1711 cm−1 due to the symmetrical carbonyl stretching vibrations, at ~1380 cm−1 caused by the C–N stretching vibrations, at 1508 cm−1 due to the stretching vibration of C=C in benzene rings in the diamine units, and at ~2933 cm−1 from the saturated C–H (–CH2–) absorptions in the dianhydride units. The differences mainly relate to the characteristic absorptions at ~1317 cm−1 due to the asymmetrical stretching of C–F bonds in –CF3 groups, and at 1120 cm−1 due to the –O– linkages, which were only detected in the spectra of the CPI-ref1 and CPI-ref2 polymers.

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].

CPI Resins Synthesis and Films Preparation\"], \"source_text\": \"Four CPI resins, including the ones derived from ccHPMDA (I) and FDA (a) (CPI-Ia), from ccHPMDA (I) and FFDA (b) (CPI-Ib), from ctHPMDA (II) and FDA (a) (CPI-IIa), and from ctHPMDA (I) and FFDA (b) (CPI-IIb), were prepared according to the formula shown in Table 1. CPI-Ia (ccHPMDA-FDA) was used to show the detailed synthesis procedure. Into a 1000 mL three-necked flask settled in a thousand-class clean room we added anhydrous GBL (100 g) and FDA (34.844 g, 0.1 mol). Dry nitrogen was passed through the diamine solution. 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. The solution was slowly added into the aqueous ethanol solution (70 vol%) to form threadlike precipitants. The resin was immersed into the ethanol solution for 24 h and collected. The resin was first dried in an air-circulating environment and then transferred into a vacuum-drying oven and dried in vacuo at 120 °C overnight. Lastly, the CPI-Ia resin was obtained in the form of flexible and tough silky solids. Yield: 51.9 g (96.7%). Numeric average molar mass (Mn): 8.11 × 104 g/mol.

CPI-Ia (ccHPMDA-FDA) was used to show the detailed synthesis procedure. Into a 1000 mL three-necked flask settled in a thousand-class clean room we added anhydrous GBL (100 g) and FDA (34.844 g, 0.1 mol). Dry nitrogen was passed through the diamine solution. 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. The solution was slowly added into the aqueous ethanol solution (70 vol%) to form threadlike precipitants. The resin was immersed into the ethanol solution for 24 h and collected. The resin was first dried in an air-circulating environment and then transferred into a vacuum-drying oven and dried in vacuo at 120 °C overnight. Lastly, the CPI-Ia resin was obtained in the form of flexible and tough silky solids. Yield: 51.9 g (96.7%). Numeric average molar mass (Mn): 8.11 × 104 g/mol.

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. The solution was slowly added into the aqueous ethanol solution (70 vol%) to form threadlike precipitants. The resin was immersed into the ethanol solution for 24 h and collected. The resin was first dried in an air-circulating environment and then transferred into a vacuum-drying oven and dried in vacuo at 120 °C overnight. Lastly, the CPI-Ia resin was obtained in the form of flexible and tough silky solids. Yield: 51.9 g (96.7%). Numeric average molar mass (Mn): 8.11 × 104 g/mol.

CPI-Ia (ccHPMDA-FDA) was used to show the detailed synthesis procedure. Into a 1000 mL three-necked flask settled in a thousand-class clean room we added anhydrous GBL (100 g) and FDA (34.844 g, 0.1 mol). Dry nitrogen was passed through the diamine solution. 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. The solution was slowly added into the aqueous ethanol solution (70 vol%) to form threadlike precipitants. The resin was immersed into the ethanol solution for 24 h and collected. The resin was first dried in an air-circulating environment and then transferred into a vacuum-drying oven and dried in vacuo at 120 °C overnight. Lastly, the CPI-Ia resin was obtained in the form of flexible and tough silky solids. Yield: 51.9 g (96.7%). Numeric average molar mass (Mn): 8.11 × 104 g/mol.

As for TFT tests, a TEG was fabricated on the PI, and the charge was injected by AC signals (180 Hz, 300 V) via two electrodes (Figure 4B). Next, changes in TFT characteristics were tested. The charge generated during the test passed through the film layer at the screen edge and eventually accumulated in the PI, which would trigger the bottom gate-like effects model to affect the characteristics of the TFT [11].

A copper rod was rubbed across the screen surface in a defined path for several hours, or an electric field could be used to generate a direct charge to reduce the time required for the test. CIE and brightness were measured in a specific image after the tests. As for TFT tests, a TEG was fabricated on the PI, and the charge was injected by AC signals (180 Hz, 300 V) via two electrodes (Figure 4B). Next, changes in TFT characteristics were tested. The charge generated during the test passed through the film layer at the screen edge and eventually accumulated in the PI, which would trigger the bottom gate-like effects model to affect the characteristics of the TFT [11]. Typically, green had the highest light-emitting efficiency, so it was usually displayed with a greenish color. TFT characteristics and CIEs of different samples after testing are shown in Table 4. The ΔVth of sample 470 was as low as 0.36 V, but for sample 350 it could be as high as 1.12 V. In contrast, when glass was chosen as the substrate, the voltage was around 0.02 V.

PI is a semi-crystalline polymer, and a fluctuation of electron density occurs between the crystalline and amorphous regions [19]. SAXS is an effective way to investigate this. Experimental data are presented in Figure 2A, where q is the scattering vector and I(q) is the scattering intensity. 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]. The correlation function can be solved by the Fourier transform of I(q)~q to calculate the periodicity [21], and data are presented in Figure 2B and Table 2. The long period decreased from 41 to 35.9 Å, crystalline thickness decreased from 8.16 to 7.58 Å, amorphous thickness from 32.84 to 28.32 Å, and polydispersity from 20.9 to 16.7%, whereas crystallinity increased from 19.90 to 21.11%. The crystal structure was further confirmed by XRD (Figure S7). Three samples showed two weak and broad peaks at 20 and 26°, with slightly higher crystallinity in sample 470, which is in agreement with SAXS data. This indicated that as the process temperature increased, segments of the amorphous region within the PI underwent significant shrinkage. These data indicated that as the process temperature increased, chains in the amorphous region within the PI underwent contraction and the crystalline region developed, while the crystal structure of the crystalline region remained unchanged.

PI is a semi-crystalline polymer, and a fluctuation of electron density occurs between the crystalline and amorphous regions [19]. SAXS is an effective way to investigate this. Experimental data are presented in Figure 2A, where q is the scattering vector and I(q) is the scattering intensity. 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]. The correlation function can be solved by the Fourier transform of I(q)~q to calculate the periodicity [21], and data are presented in Figure 2B and Table 2. The long period decreased from 41 to 35.9 Å, crystalline thickness decreased from 8.16 to 7.58 Å, amorphous thickness from 32.84 to 28.32 Å, and polydispersity from 20.9 to 16.7%, whereas crystallinity increased from 19.90 to 21.11%. The crystal structure was further confirmed by XRD (Figure S7). Three samples showed two weak and broad peaks at 20 and 26°, with slightly higher crystallinity in sample 470, which is in agreement with SAXS data. This indicated that as the process temperature increased, segments of the amorphous region within the PI underwent significant shrinkage. These data indicated that as the process temperature increased, chains in the amorphous region within the PI underwent contraction and the crystalline region developed, while the crystal structure of the crystalline region remained unchanged.

Results\"], \"source_text\": \"Dielectric and trap properties were directly related to friction-greening. The dielectric constant was in the order of sample 350 ˃ sample 470 ˃ sample 450 (Figure 3A). Dipole polarization occurred within 20 Hz–20 MHz, which was related to the orientation and polarizability of the material. 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]. Another key parameter, conductivity, is shown in Figure 3B.

Introduction\"], \"source_text\": \"However, compared to glass as a substrate, the use of PI raises some new problems. 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.

Introduction"], "source_text": "However, compared to glass as a substrate, the use of PI raises some new problems. 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"}, "source_group": "doi:10.3390/polym16233253", "source_text_truncated": false, "split": "test", "source_index_candidate": {"variant": "index_only", "source_only_index_payload_sha256": "21baabb5a342d1b24fe9f3d87d951038640ab9502ff958583d3b6792779abe10", "boundary_tokens": 243, "source_length_codepoints": 1441, "original_messages_sha256": "c62cdb4dc3842c71b059f9e294961a93f9c7d201302c69201bd03873ca5cb348", "deterministic_boundary_index_is_additional_input": true, "reference_or_review_used_to_build_prompt": false, "post_generation_repair": false}, "semantic_messages_sha256": "636b9ead1718841875cff5e725109ea909f4dfcd0dd47d90230f2dee2ee059ad"}

Introduction\"], \"source_text\": \"The ongoing trend toward miniaturization and weight reduction in power electronic systems has significantly increased the demand for capacitor polymer films that exhibit both high energy storage density and superior thermal stability [1,2,3,4,5]. 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:

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"}, "source_group": "doi:10.3390/polym17060753", "source_text_truncated": false, "split": "test", "source_index_candidate": {"variant": "index_only", "source_only_index_payload_sha256": "65ad94c0619c814089d38ea12bc318cf24cf31f8013e27c1045146a61c349944", "boundary_tokens": 210, "source_length_codepoints": 1777, "original_messages_sha256": "19bdcf29a0967ab666c181da9486b9ec6cbd40adf069fa1e46301451668bc160", "deterministic_boundary_index_is_additional_input": true, "reference_or_review_used_to_build_prompt": false, "post_generation_repair": false}, "semantic_messages_sha256": "9934458be4ea87148c9f6e17ea688de3614fb3ef5e8d7f0d399352394da5ca94"}

Results and Discussion\", \"3.2. Electrical Insulation\"], \"source_text\": \"The conjugated structure of the benzene ring in PI and the lone pairs of electrons on O and N in the imide ring contribute to the high electron mobility of PI, leading to electron polarization [37]. Due to the small contribution of electron polarization, the dielectric constant of PI is mainly determined by the dipole polarization contributed by polar groups [5]. 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]. Under an external electric field, these polar groups rotate and orient in the direction of the field, resulting in good dipole polarization, as shown in Figure 3. PI-0% has the best dielectric properties among all proportions, with a ξγ of 4.5 at a frequency of 1 kHz, while that of PI-100% is only 3.4, which is because the nonpolar group -CF3 in the TFMB diamine monomer is less prone to polarization under the action of an external electric field and has a slower response to the electric field. It is worth noting that as the content of the TFMB diamine monomer decreases in the copolymer proportion, the dielectric constants of the copolymer PI increase to varying degrees: PI-80%, PI-60%, PI-50%, PI-40%, and PI-20% have values of 4, 4.2, 3.9, 4.3, 4.3, and 4.5, respectively (Figure 3a). The introduction of the BABP monomer forms a conjugated structure between the -C=O and the benzene ring, which is beneficial for electron movement and polarization [39].

Due to the small contribution of electron polarization, the dielectric constant of PI is mainly determined by the dipole polarization contributed by polar groups [5]. 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]. Under an external electric field, these polar groups rotate and orient in the direction of the field, resulting in good dipole polarization, as shown in Figure 3. PI-0% has the best dielectric properties among all proportions, with a ξγ of 4.5 at a frequency of 1 kHz, while that of PI-100% is only 3.4, which is because the nonpolar group -CF3 in the TFMB diamine monomer is less prone to polarization under the action of an external electric field and has a slower response to the electric field. It is worth noting that as the content of the TFMB diamine monomer decreases in the copolymer proportion, the dielectric constants of the copolymer PI increase to varying degrees: PI-80%, PI-60%, PI-50%, PI-40%, and PI-20% have values of 4, 4.2, 3.9, 4.3, 4.3, and 4.5, respectively (Figure 3a). The introduction of the BABP monomer forms a conjugated structure between the -C=O and the benzene ring, which is beneficial for electron movement and polarization [39]. This characteristic also allows it to maintain good thermal stability and polarization performance over a wider temperature range, indicating that the copolymer effectively integrates the advantageous functional groups carried by the BABP diamine monomer.", "title": "Polyimide Modified with Different Types and Contents of Polar/Nonpolar Groups: Synthesis, Structure, and Dielectric Properties"}, "source_group": "doi:10.3390/polym17060753", "source_text_truncated": false, "split": "test", "source_index_candidate": {"variant": "index_only", "source_only_index_payload_sha256": "0a8cefef5e26c8bec0635d684048262fb56129566cd9745db64a073e8c9e2b88", "boundary_tokens": 281, "source_length_codepoints": 1726, "original_messages_sha256": "c8b36e596fe950e79477c5bc4a27d93d16f1aafd4ced3ec0c6949fd36429e1e2", "deterministic_boundary_index_is_additional_input": true, "reference_or_review_used_to_build_prompt": false, "post_generation_repair": false}, "semantic_messages_sha256": "3d2b483c0071753076baa126c26b2d783ab4fcce607b5883e38a8c51c618ee08"}

While oxide additives can form effective passivation layers, in composites containing more than one filler, their protective function can be compromised when dispersion is uneven or interfacial compatibility is lacking, leading to morphological instability and increased erosion susceptibility [53].", "title": "Polyimide Reinforced with Graphene/Metal Oxide Nanocomposites: Surface Degradation Study Under Atomic Oxygen"}, "source_group": "doi:10.3390/polym18040522", "source_text_truncated": false, "split": "test", "source_index_candidate": {"variant": "index_only", "source_only_index_payload_sha256": "83b2a6b134d82a205ebec852c4015fe0697f088ddfd73e0e627ebfc18da2a8c3", "boundary_tokens": 154, "source_length_codepoints": 1078, "original_messages_sha256": "504b0b0393c391bac87881914b34bb3c05b35ee171dcbed4cbd88aa5c59965b5", "deterministic_boundary_index_is_additional_input": true, "reference_or_review_used_to_build_prompt": false, "post_generation_repair": false}, "semantic_messages_sha256": "9012456aa203960cee1a367234c7e081d7cffc93c7f606040128534aa8b8de29"}

It is evident that pure PI has a relatively smooth surface, whereas the introduction of graphene at 0.25% increases the size of protrusions, resulting in the formation of larger, irregularly shaped features on the surface that can be associated with the presence of isolated graphene aggregates.

As shown in Table 1, the obtained PAs had inherent viscosities in the range of 0.35−0.62 dL g−1. Polyamides 5a–5c can be solution-cast into flexible and transparent films (see photos shown in Scheme 2), indicating the formation of high molecular weight polymers. Although 5d and 5e have relatively lower inherent viscosities, they can still be casted into robust films on the glass substrates. Their cast films are highly transparent and colorless. The structures of the PAs were confirmed by IR and NMR spectroscopy. Figure S4 (Supplementary Materials) shows the IR spectra of PAs 5a−5e. All of the PAs showed the characteristic absorption bands of the amide group at around 3315 cm−1 (N−H stretching) and 1664 cm−1 (amide C=O).

As shown in Table 1, the obtained PAs had inherent viscosities in the range of 0.35−0.62 dL g−1. Polyamides 5a–5c can be solution-cast into flexible and transparent films (see photos shown in Scheme 2), indicating the formation of high molecular weight polymers. Although 5d and 5e have relatively lower inherent viscosities, they can still be casted into robust films on the glass substrates. Their cast films are highly transparent and colorless. The structures of the PAs were confirmed by IR and NMR spectroscopy. Figure S4 (Supplementary Materials) shows the IR spectra of PAs 5a−5e. All of the PAs showed the characteristic absorption bands of the amide group at around 3315 cm−1 (N−H stretching) and 1664 cm−1 (amide C=O).

The decay in electrochromic coloration efficiency (CE = ΔOD/Qd) after various switching steps for PA 5b is shown in Table 4. PA 5b exhibited good coloration efficiencies of up to 186 cm2 C−1 at 828 nm at the first switching cycle. It did not lose the electrochromic activity significantly and retained about 95% of its optical response after 100 switching cycles. Therefore, the electrochromic switching behavior of PAs appears to be a highly reversible process. In contrast, PI 7a exhibited a higher oxidation potential and significantly decreased the cycling stability than the corresponding PA 5b analog.

Previous studies have reported that there is a good correlation between the CTE and ∆nth for wholly aromatic PIs [40,41]. Similarly, for a variety of semi-cycloaliphatic PI systems, a relatively good correlation is observed between them [20,21,36,37], even though, strictly speaking, it is difficult to compare the extent of the in-plane orientation between different systems because the intrinsic birefringence (∆n0) depends on the chain structures [61]. Therefore, the comparisons can be conducted within a fixed type of PIs (e.g., semi-cycloaliphatic PIs derived from cycloaliphatic tetracarboxylic dianhydrides and aromatic diamines) under the assumption that the ∆n0 values do not significantly differ each other. Empirically, low-CTE films (CTE < 20 ppm·K−1) usually have high ∆nth values (roughly speaking, >0.05–0.1 for semi-cycloaliphatic PIs), reflecting the high degree of in-plane orientation. When a contradiction is observed between the estimated CTE and ∆nth values, [e.g., the CTE is low (<20 ppm·K−1), but the ∆nth is also low (<0.01–0.02)], there is the possibility that the CTE

In particular, note that the light transmittance at longer wavelengths such as 450 or 500 nm is a less useful parameter for evaluating the film coloration because the films are not always colorless even if the T500 value is very high (e.g., T500 > 80%).", "title": "Development of Solution-Processable, Optically Transparent Polyimides with Ultra-Low Linear Coefficients of Thermal Expansion"}, "source_group": "doi:10.3390/polym9100520", "source_text_truncated": false, "split": "test", "source_index_candidate": {"variant": "index_only", "source_only_index_payload_sha256": "cf1e13eae10da0eea50b749a66d3f916efbceddaaf9d38c923188f8ba5f3fddf", "boundary_tokens": 176, "source_length_codepoints": 1025, "original_messages_sha256": "f4e951510f938eb27dce1a5c4ff2602de435f0e917de01e083bde11798fee408", "deterministic_boundary_index_is_additional_input": true, "reference_or_review_used_to_build_prompt": false, "post_generation_repair": false}, "semantic_messages_sha256": "60fbfd71e67ed3d918d7b7ec0a506c82fb28ce0202d649c4a7e1f214f844c55a"}
