] | Silica which is used for reinforcing filler in tire industry is widely known as eco-friendly material exerting CO2 reduction effect through decrease of rolling resistance and improvement of wet grip. Generally silica is classified as a highly polar filler because it contains a large number of silanol (Si-OH) group on its surface. And also silica gives a lower reinforcing effect than carbon black due to its poorer rubber-filler interaction. Therefore silica is treated with silane coupling agent or activator, then following the conventional rubber blend method, vulcanized sheets were prepared using a hot press, and cure characteristics, mechanical properties and abrasion resistance of the test specimens were investigated. It was found that with an increase in the silane coupling agent content the tensile strength, 300% modulus and abrasion resistance increased while Mooney viscosity decreased and crosslink density slightly increased with an increase of activator. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

] | Bacterial infection is one of the most common and universal cause of disease spreading associated with medical and surgical environment. Antimicrobial function of plasticized polyvinyl chloride (PVC) will be useful for making hygienic environments. Here, we synthesized the PVC composite by the addition of inorganic bacteriocide containing silver, zinc and zeolite. And we investigated the growth inhibition rate for Staphylococcus aureus and Klebsiella pneumoniae which were analyzed in the presence of PVC composite with different doses of inorganic bacteriocide (1~15 wt%). Bacterial proliferation was significantly inhibited by 3 wt% of inorganic bacteriocide containing PVC composite. And we found the inhibition of bacterial biofilm formation by 5 wt% of inorganic bacteriocide containing PVC composite by the observation of scanning electron microscopy (SEM). Our data suggested that the antimicrobial effect of inorganic bacteriocide was caused by disturbing the bacterial biofilm formation. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

] | Crosslink density of a rubber vulcanizate determines the chemical and physical properties, while bound rubber is an important factor to estimate reinforcement of a filled rubber compound. Extender oil is added to a raw rubber with very high molecular weight for improving processability of a rubber composite. Influence of extender oil on crosslink density, bound rubber formation, and physical properties of solution styrene-butadiene rubber (SSBR) composites with differing microstructures was investigated. Crosslink densities of non-oil-extended SSBR (NO-SSBR) vulcanizates were higher than those of oil-extended SSBR (OE-SSBR) ones. Bound rubber contents of NO-SSBR compounds were also greater than those of OE-SSBR ones. The experimental results could be explained by interfering of extender oil. The OE-SSBR vulcanizates had low modulus but long elongation at break, whereas the NO-SSBR ones had high modulus but short elongation at break.
It was found that the crosslink densities affected the physical properties more than the bound rubber contents. The moduli increased with increase in the crosslink density irrespective of extender oil, while the elongation at break decreased. Each variation of the tensile strengths of NO-SSBR and OE-SSBR vulcanizates with the crosslink density showed a decreasing trend. Tear strength of the OE-SSBR vulcanizate increased with increase in the crosslink density, whereas variation of the tear strength of NO-SSBR vulcanizate with the crosslink density showed a weak decreasing trend. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

] | Methylene diisocyanate (MDI) was investigated as a novel interfacial modifier to enhance the performances of poly(methyl methacrylate)-modified starch/styrene-butadiene rubber (PMMA-modified starch/SBR) composites. Owing to the formation urethane linkage on one side and ฯ-ฯ adhesion on the other side, MDI acted as an intermediated linkage role in the PMMA-modified starch/SBR interfaces, which was evidenced by the morphological, mechanical, dynamic mechanical and thermal decomposition studies. As a result, the presence of MDI significantly improved the mechanical properties and thermal stability of PMMA-modified starch/SBR composites. In addition, the effect of starch concentration on the various performances of the resulted MDI/PMMA-modified starch/SBR composites, such as morphology, vulcanization characteristics, mechanical properties, toluene swelling behavior, and thermal stability were investigated and discussed in detail. The obtained MDI/PMMA-modified starch/SBR composites exhibited superior mechanical properties to carbon black/SBR (CB/SBR) composites, demonstrating the potential use of the renewable starch as a substitute for CB in the rubber compounds. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

] | Sodium-montmorillonite (Na+-MMT) was introduced into single wall carbon nanotube (SWCNT)/epoxy compositeto investigate the effect of MMT size and MMT/SWCNT ratio on the mechanical and electrical properties of composite.
Three different sizes of MMTs were used and all were found to function as effective dispersion aids for SWCNTs. Mechanicalproperties of SWCNT/epoxy composite increased with MMT content; tending to decrease once the MMT content reacheda critical level. However, the surface electrical resistance decreased with increasing MMT content and tended to increaseafter the critical content was reached. Critical MMT/SWCNT ratio for maximum mechanical properties and minimum electricalresistivity was strongly dependent on the MMT size. Critical MMT/SWCNT ratio was decreased with MMT size. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

] | Multi-Surface (MS) treatment is a new technique of surface treatment to reduce the static friction factor on the surface of rubber. MS treatments include 4 methods which names are MS-V (UV-irradiation on the rubber surface), MSM (doing the chemical reaction with double bond of rubber), MS-Q (dilution of rubber surface by silicone surfactant), and MS-P (coating and heating of rubber surface). The experiment and test of every MS-treatment had been carried out using acrylonitrile-butadiene rubber (NBR), ethylene-propylene-diene rubber (EPDM), and chlorosulphonated rubber (CSM) as rubber materials. It had introduced the steps of every MS-treatment process and the result of the properties test. From the research, it was found that the best method was MS-V treatment because it suited all the samples and the effect was obviously. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

] | Characterization of the UV oxidation for raw natural rubber (NR) was investigated in controlled conditions through image and FT-IR analysis. The UV oxidation was performed on a thin film of natural rubber coated on a KBr window at 254 nm and room temperature to exclude the thermal oxidation. Before or after exposure to UV light, image of the NR thin film was observed at a right or tilted angle. FT-IR absorption spectra were measured in transmission mode with the UV irradiation time. The UV oxidation of NR was examined by the changes of absorption peaks at 3425, 1717, 1084, 1477, 1377, and 833 cmโ1 which were assigned to hydroxyl group (-OH), carbonyl group (-C=O), carbon-oxygen bond (-C-O), methylene group (-CH2-), methyl group (-CH3), and cis-methine group (cis-CCH3=CH-), respectively. During the initial exposure period, the results indicated that the appearance of carbonyl group was directly related to the reduction of cis-methine group containing carbon-carbon double bond (-C=C-). Most of aldehydes or ketones from carbon-carbon double bonds were formed very fast by chain scission. A lot of long wide cracks with one orientation at regular intervals which resulted in consecutive chain scission were observed by image analysis. During all exposure periods, on the other hand, it was considered that the continuous increment of hydroxyl and carbonyl group was closely related to the decrement of methylene and methyl group in the allylic position. Therefore, two possible mechanisms for the UV oxidation of NR were suggested. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

] | The isothermal crystallization behaviors of blends of poly(ethylene naphthalate) (PEN) and a thermotropic liquid crystalline polymer (TLCP) were investigated by differential scanning calorimetry (DSC) as functions of crystallization temperature and blend composition. Avrami analyses were applied to obtain information on the crystal growth geometry and the factors controlling the rate of crystallization. The crystallization kinetics of the PEN/TLCP blends followed the Avrami equation up to a high degree of crystallization, regardless of crystallization temperature. The calculated Avrami exponents for PEN/TLCP revealed three-dimensional growth of the crystalline region in each blend. The crystallization rate of each blend increased as the crystallization temperature decreased, and decreased as the TLCP content increased. The crystallization of PEN in the blend was affected by the addition of TLCP, which acts as a nucleating agent. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

EVA film for deacetylation was prepared by solution casting on aluminum foil and it was pyrolyzed at low temperature of 300oC in the off-line pyrolysis apparatus. After deacetylation, carbon-carbon double bond (C=C) was formed by 1,2-elimination of the VA unit in the EVA backbone. Most of C=C bonds were trans-1,4-unit and 1,2-unit was also observed. Presence of the 1,2-unit in deacetylated EVA indicates that terminal or branch VA units exist in the raw EVA.
Py-GC/MS chromatogram of deacetylated EVA displayed much smaller acetic acid and much more abundant other pyrolysis products than that of raw EVA, which means that the pyrolysis efficiency and separation condition were improved. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

In this study, we investigated rheological properties for polymer resin filled with the different type and concentration of foaming agent, capsule type foaming agent and organo-chemical foaming agent, under the time sweep test. Curing times of each polymer resin with different kind of foaming agent are delayed than reference material (epoxy resin with curing agent). In case of adding capsule type foaming agent, however, there is appropriate concentration to reduce the curing time, relatively. When foaming agent is activated, foaming force inflates the sample in contrast to condensation force of curing and then axial normal force develop to the (+) direction. Interestingly, by increase concentration of foaming agent, there is a specific point to break down the axial normal force development. The reason for this phenomenon is that coalescence of foams induce the blocking of axial normal force development. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

Also, we examined the effects of dicumyl peroxide (DCP) and 2,5-dimethyl-2,5-di-(tert-butylperoxy)-hexane (DTBPH) as peroxide type cross-linking agents to enhance the properties of TPVโs. The components of RPP and WGRT were fixed at 30 and 70 wt%, and DCP and DTBPH were added in the concentrations from 0.5 to 1.5 phr, respectively. RPP/WGRT composites with different contents of DCP and DTBPH were prepared by a modular intermeshing co-rotating twin screw extruder. The Youngโs modulus of composites were decreased with increasing peroxides contents. On the other hand, tensile strength, elongation at break, and impact strength of the composites were increased with peroxide contents. We also confirmed that interfacial adhesion between RPP and WGRT was considerably improved by adding the peroxides. Taken together, DTBPH added RPP/WGRT composites exhibited better mechanical properties rather than those of DCP added composites. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

The experimental conditions include roughness level, applied pressure, lubrication, and rubbing speed. The design of experiment approach is taken to assess the effect of each parameter. The nonlinear frictional response of the rubber is applied to the FEM model simulating the servo cylinder movement. The result demonstrates that precise optimization of the servo cylinder movement must be preceded by preliminary experiments coupled with the theory and FEM model. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

] | Biomimetic artificial basilar membrane being a core part of artificial cochlear requires performance evaluation through aging test. To evaluate the aging properties of PVDF piezoelectric membrane used for artificial basilar membrane, its mechanical properties such as tensile strength and elastic modulus and piezoelectric property such as piezoelectric constant were measured. The aging test conditions and acceleration constants were calculated based on Arrhenius model. The changes in tensile strengths and elastic moduli measured were less than 10~20% after aging test equivalent for 10 years.
The piezoelectric constants were decreased drastically to 80% of its initial value in the early stage of the aging test and expected to decrease slowly down to 65% over 10 years. The experimental results show the reliability of totally implantable novel artificial cochlear and will contribute its commercialization. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

It was found that the asphalt together with Span 20, nonionic surfactant and DDA (Dimethyl Dodecyl Amine), cationic surfactant showed the most stable phase. The phase stability of the emulsified asphalt, therefore, was investigated through the particle size with mixed surfactant content, rheology behavior and Zeta potential value; the particle size decreased with the increase of the mixed surfactant content but the viscosity increased. The shear thinning behaviors and the Zeta potential value with 50 mV~60 mV were shown, which was found to be considered stable. In addition, SBR latex(Styrene-butadiene-rubber) and water dispersed Epoxy (EPD) were used to enhance the physical properties of the emulsified asphalt. The swelling and adhesion features of the emulsified asphalt were also studied with CaCO3, Silica, and Montmorillonite (MMT). It was shown that the addition of SBR latex and MMT can be another way to improve the physical properties of the emulsified asphalt in that the lowest swelling feature was found. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

The polymerization conditions had a significant effect on the properties of the synthesized PVAc. When hydrogen peroxide and tartaric acid as the initiator for redox polymerization were used, the synthesized PVAc had a low molecular weight. In comparison with thermal polymerization, smaller PVAc particles were formed during the redox polymerization due to relatively faster polymerization rate, which in turn resulted in improved adhesion property. It is considered that the rapid generation of smaller particles induces the formation of a large surface area. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

EPDM scrap powder was prepared by shear pulverization process at high temperature, which may lead to selective chain scission induced by difference in the critical elastic coefficient. On the other hand, EPDM scrap powder was prepared by adding a selected reclaiming agent during shear pulverization process at high temperature. Terpene as a bonding agent was then introduced to improve adhesion property. PP, used as a matrix for manufacturing thermoplastic elastomer, was modified by the incorporation of dicumyl peroxide and maleic anhydride. The functionalized EPDM and modified PP were blended and cured dynamically at 190oC. The blend materials prepared in this study showed the comparable results to those of conventional TPE in terms of tensile and flow properties.

A number of thermograms were obtained at several constant heating rates, and analysed using FlynnโWallโOzawa (FWO) isoconversional method for activation energy, E a and extended-Avrami equation for reaction order, n. Urea formation reaction of the present system was observed to occur through the simple exothermic reaction process in the temperature range of 100 ~ 130oC for the heating rate of 3 ~ 7 oC/ min. and could be well-fitted with generalized sigmoid function. Though activation energy was nearly constant as 53.0ยฑ0.5 kJ/mol, it tended to increase a little at initial stage, but it decreases at later stage by the transformation into diffusionโcontrolled reaction due to the increased viscosity. Reaction order was evaluated as about 2.8, which was somewhat higher than the generally well-known 2nd order values for the various urea reactions. Both the reaction order and reaction rate explicitly increased with temperature, which was considered as the indication of occurring the side reactions such as allophanate or biuret formation. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

It is expected that amine group introduced to a rubber molecule would improve dispersion of silica by the formation of hydrogen bond (or ionic coupling) between the amine group and silanol groups of silica surface.
The chemical structure of DEAEMA-SBR was analyzed using proton nuclear magnetic resonance spectroscopy (H-NMR), Fourier transform infrared spectroscopy (FTIR), gel permeation chromatography (GPC) and differential scanning calorimetry (DSC). Then, various properties of DEAEMA-SBR/silica composite such as crosslink density, bound rubber content, abrasion resistance, and mechanical properties were evaluated. As a result, bound rubber content and crosslink density of DEAEMA-SBR/silica compound were higher than those of the SBR 1721 composite. Abrasion resistance and moduli at 300% elongation of the DEAEMA-SBR/silica composite were better than those of SBR 1721 composite due to the high bound rubber content and crosslink density. These results are attributed to high affinity between DEAEMA-SBR and silica.
The proposed study suggests that DEAEMA-SBR can help to improve mechanical properties and abrasion resistance of the tire tread part. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

In case of epoxy/anhydride compounds used surface unmodified silica by coupling agent, these compounds need excess anhydride unlike the weight ratio in the conventional epoxy/anhydride compounds. In curing behavior, the epoxy/anhydride compounds containing chromium (III) octoate showed high conversions at 71ยฐC for 40 hr, even if a dipropylene glycol (DPG) was not used as a polymerization initiator. Also, DPG leads to a poor epoxy network structure. In conclusion, the appropriate weight ratio of Part A/Part B of highly silica filled epoxy/anhydride compounds with chromium (III) octoate catalyst is 0.5/1.0 and the maximum amounts of silica is 1470 phr of epoxy resin. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

However, PVC is vulnerable to heat deformation and generates a toxic gas like hydrogen chloride. Therefore, it is important to delay or prevent the flame retardancy and thermal degradation of the PVC during the processing. It was reported that aluminum trihydroxide (ATH) improved flame retardancy as well as smoke inhibition of the virgin polymer. In this study, PVC composites by addition of ATH were compounded in a modular intermeshing co-rotating twin screw extruder. The PVC composites with different concentrations of ATH (0~5 phr) were analyzed. Flame retardancy of the PVC composite significantly increased depending on the ATH concentration.

] | The effect of the surface area of silicas on their reinforcing performance to styrene-butadiene rubber (SBR) compounds was systematically investigated. The feasibility of the Brunauer-Emmett-Teller surface area (SBET) as a parameter representing the characteristics of the silicas was discussed compared to the mesopore volume, c value, oil absorption, and uptake of silane. The increase in SBET of silicas caused a considerable increase in Mooney viscosity, minimum torque, and hysteresis loss of the silica-filled SBR compounds, while significantly enhancing their abrasion property. These changes were explained by the attrition between the hydrophilic silica surface and the hydrophobic rubber chains. As expected, the change in SBET did not induce any remarkable changes in the cure, processing, tensile, and dynamic properties of the silicafilled SBR compounds because the crosslinking density of the rubber chains mainly determined these properties. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

] | The composites of EVA/EPDM including aluminum trioxide (ATH) as a fire retardant were manufactured for the purpose of improving low temperature property and flame resistance in the rubbery materials. The ratio of EVA to EPDM didnโt affect the flame resistance of the rubber composites. The addition of ATH resulted in increase of the flame resistance. In the evaluation of the cold resistance, the increasing EPDM content showed enhancement of cold resistance in the composites due to increasing low Tg EPDM. It was found out that tensile strengths of the composites showed a maximum value at 100 phr of ATH by reinforcing effect, but a minimum value at 200 phr of ATH owing to slippage between the flame retardant by the external stress. In the measurement of solvent resistance in tetrahydrofuran, the increasing ATH content yielded enhancement of solvent resistance by reducing swelling of the composite, and increasing EPDM content also resulted from increase of the solvent resistance by reduction of polarizability as well as increase of crosslink in the composites. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

] | 1,3-Diphenylguanidine (DPG) is commonly used as a secondary accelerator which not only acts as booster of cure but also activating silanization reaction. The aim of this study is to increase the interaction between silica and rubber by using DPG. In this study, mixing was proceeded in two steps. The T-1 compound is mixed DPG with silica and silane coupling agent in the kneader at high temperature which is named as 1st mixing step. T-3 compound is mixed DPG with curatives in the two-roll mill at low temperature which is named as 2nd mixing step. The T-2 compound is mixed a half of DPG in 1st mixing step and the remainder is mixed in 2nd mixing step. Total DPG content was equal for all compounds. When DPG is mixed with silica, silane coupling agent during the 1st mixing step, a decrease in cure rate and an increase in scorch time can be seen. This indicates that DPG is adsorbed on the surface of silica. during rubber processing. However, bound rubber content is increased and dynamic properties are improved. These results are due to the highly accelerated silanization reaction. However, there are no significant difference in 100%, 300% modulus. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

] | Magneto-rheological elastomer (MRE) is a material which shows reversible and various modulus under magnetic field. Comparing to conventional rubber vibration isolator, MREs are able to absorb broader frequency range of vibration. These characteristic phenomena result from the orientation of magnetic particle (i.e., chain-like formation) in rubber matrix. In this study, silicone rubber was used as a matrix of MREs. Carbonyl iron particle (CIP) was used to give magnetic field reactive modulus of MRE. The surface of the CIP was modified with chemical reactants such as silane coupling agent and poly(glycidyl methacrylate), to improve interfacial adhesion between matrix and CIP. The mechanical properties of MREs were measured without the application of magnetic field. The results showed that the tensile strength was decreased while the hardness was increased with the addition of CIP. Also, surface modification of CIP resulted in the improvement of physical properties of MRE, but the degree of orientation of CIP became decreased. The analysis of MR effect was carried out using electromagnetic equipment with various magnetic flux. As the addition of CIP and magnetic flux increased, increment of MR effect was observed. Even though the surface modification of CIP gave positive effect on the mechanical properties of MRE, MR effect was decreased with the surface modification of CIP due to decrease of CIP orientation. Throughout this study, it was found that the loading amounts of CIP affected the mechanical properties of MRE, and surface property of CIP was an important factor on MR effect of MRE. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

In order to simulate a commercial TPV,the component of waste PP and WGRT was fixed at 30 and 70 wt%, respectively. With the simple addition of SEBS-g-MA into the waste PP/WGRT composites, the tensile strength of the composite was decreased, whereas both the elongationat break and impact strength were significantly increased because of rubbery characteristics of SEBS-g-MA. In order to furtherimprove the properties of the composites, the waste PP/WGRT/SEBS-g-MA composites was revulcanized with dicumylperoxide (DCP). As expected, mechanical properties of the revulcanized composites was generally improved. Especially,with 15 and 1 phr of SEBS-g-MA and DCP, elongation at break was highest value of about 183% because of the recrosslinkingof WGRT without chain scission of the main chain. It was found that complex viscosity of the revulcanized compositeincreased which might verify further vulcanization of the WGRT. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

Thermo-mechanical deformation of the sample OC-RPUF was shown to occurfrom about 120oC. Yield stress of 0.36 MPa was shown at about 10% yield strain. And, densification of the foam startedto occur from 75% compressive strain and could be continued up to max. 90%. Compression set of the sample restoredafter initial compression to 90% at room temperature was ca. 82%. Though the expansion occurred to about twice of theoriginally compressed thickness in case of temperature rise to 130oC, it could be overcome and the dimensional stabilitycould be maintained if the constant load of 0.3 MPa was applied. As the result, a thermo-mechanical treatment process, i.e,annealing process at temperature of 130~140oC for about 20 min as is the maximum compressed state at room temperature,should be required for dimensional stability as an optimum condition for the use of VIP core material. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

Discoloration and crack formation of photooxdized BR vulcanite surface were examined using an imageanalyzer. Change of chemical functional groups of BR vulcanite surface by photooxidation was investigated using ATRFTIR,and variation of the crosslink density with the UV irradiation time was investigated. By increasing the UV irradiationtime, the crosslink density steeply increased after a period of time and did not increase any more.

Temperature changes with time during foaming process were measured using a digital thermometer.
RPUF foaming process was observed to undergo 2-step processes with temperature inflection around 60 sec afterthe start of reaction, and then reached slowly the max. temperature. While the max. temperature of neat PUF was measuredas ca. 120oC, that of the samples with MWCNT were as higher value as ca. 130oC, and, even the time to reach that temperaturewas reduced by about 15 sec. Average cell size of PUF samples decreased from 185.1 for the neat PUF to 162.9ฮผm for the sample of 0.01 phr of MWCNT.

There are severaladsorption methods of glass substrate such as atmospheric pressure, vacuum and electrostatic adsorption. However, thesemethods are very complex to connect system. Therefore, the adsorption method using silicone rubber based sticking chuckwas proposed in this study. Three types of silicone rubbers having 0, 19.3 and 32.2 wt% of fluorine were used and theirmechanical properties, surface energies and adsorption properties were examined. According to the results ฯ300 and hardnessincreased with increasing fluorine contents, but elongation was decreased. Also, fluorosilicone rubber containing 32.2 wt%of fluorine showed the lowest surface tension, among three types of rubber and resulted in the highest initial tack with glasssubstrate. After the adsorption-desorption test of 300,000 cycles was performed, the adsorption force of S-1 (silicone rubber)decreased largely from 2.34 to 0.73 MPa. However, the S-3 (fluorosilicone rubber having 32.2 wt%. of fluorine) decreasedonly from 3.15 to 2.24 MPa. From this study, we obtained the valuable equations related to long term durability of siliconebased sticking chuck. Finally the transfer of silicone rubber to glass substrate with the adsorption-desorption process wasnot occurred and this phenomenon was examined by UV-Visible spectroscopy. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

Crystalline nature of coated graphite is corroboratedusing XRD. Influence of carbon coated silica particles on rheometric and mechanical properties of SBR composites areinvestigated. Carbon coated silica particles showed significant improvement in rheometric and mechanical properties, whencompared to pristine silica filled system corroborating higher polymer-filler adhesion. This fact was further supported bybound rubber content and equilibrium swelling ratios of unvulcanized and vulcanized SBR composites. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

] | The effect of nanoclay (Cloisite 20A) on the self-adhesion behavior of uncured brominated-isobutylene-isoprenerubber (BIIR) has been studied. The dispersion state of nanoclay into the rubber matrix was examined by SEM, TEMand XRD analysis. The thermal degradation behavior of the filled and unfilled samples was examined by TGA and improvementin the thermal stability of the nanocomposites occurred based on the weight loss (%) measurements. Also, addition ofnanoclay enhanced the cohesive strength of the material by reinforcement action thereby reducing the degree of moleculardiffusion across the interface of butyl rubber. However, the average depth of penetration of the inter-diffused chains wasstill adequate to form entanglement on either side of the interface, and thus offered greater resistance to peeling, resultingin high tack strength measurements. The improvement in tack strength was only achieved at critical nanoclay loading above8 phr. Contact angle measurement was also made to examine the surface characteristics. There was no significant interfacialproperty change by employing the nanoclay. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

] | 3-Amino-1, 2, 4-triazole (ATA) (2.5 and 5.0 phr) was incorporated into a immiscible maleated ethylene propylenediene rubber(mEPDM)/maleated high density polyethylene(mHDPE) (50 wt%/50 wt%) blend by melt mixing. Effects of theATA on structure, mechanical and rheological properties of the blend was investigated. FT-IR and DMA results revealedthat supramolecular hydrogen bonding interactions between the polymer chains occur by reaction of ATA with maleic anhydridegrafted onto the component polymers in the blend, which induces the physical crosslinks in the blend. FE-SEM analysisshowed that mEPDM forms a dispersed phase in continuous mHDPE matrix, and the blend with the ATA has finer phasemorphology as compared to the blend without the ATA. By the addition of ATA in the blend, there were significant increasesin tensile strength, modulus and elongation-at-break as well as elastic recoverability. Melt rheology studies revealed that ATAinduced substantial increase in storage modulus and complex viscosity of the blend at the melt state. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000214.xml | |||

] | Blocking of fuel filter in aircraft greatly can affect loss of pilot's life and of the aircraft. The investigationof failures is, thus, of vital importance in preventing incidents in advance. The fuel filter of aircraft plays an importantrole in filtering various debris from jet fuel. It filters impurities smaller than 10 ใ particles from jet fuel provided withthe speed of 1,330 pounds per hour. It must be replaced per 500 h on the basis of operating time. However, even beforereaching 500 h, the warning sign lighted on due to blocking of fuel filter. Recently, these similar defects have happenedrepeatedly. Therefore, in this study, the cause of blocking fuel filter in aircraft was investigated using various analyticaltechniques such as FT-IR microscopy, FE-SEM/EDS, and total sulfur determinator. Consequently, the blocking materialof fuel filter was identified to an accelerator from the integral fuel tank sealant. And a mechanism for the formation ofthe blocking material of fuel filter by an accelerator blooming phenomenon in fuel tank was suggested. | ๊ณ ๋ถ์๊ณตํ | null | kci_detailed_000215.xml | |||
