유도되었다. TPE제조를 위해 폴리올레핀과의 블렌드 시 활성화된 EPDM 분말의 동적가황 가능성을 확인하기 위하여 가교제를 첨가하여 반응을 진행한 결과 황을 첨가할 경우 가교반응이 진행되지 않았고, DCP(dicumyl peroxide)의 경우 6 phr이 첨가되었을 때 효율적인 표면 가교반응 및 최적의 인장 물성을 나타내었다. 화학적 표면 활성화를 유도한 폐 EPDM 분말의 경우 표면활성화제의 첨가로 인해 냄새가 발생되는데, 이를 제거하기 위하여 수분흡착 공정과 rose oil 첨가 공정을 진행하였으며 GC/MS를 통해 냄새 성분을 분석하였다. -

The mechanical properties of CB-reinforced rubber composites are mostly controlled by the extent of interfacial adhesion between the CBs and the rubber. Surface treatments are generally performed on CBs to introduce chemical functional groups on its surface. In this study, we review the effects of various surface treatment methods for CBs. In addition, the preparation and properties of CB-reinforced rubber composites are discussed. -

Materials, 7, 75 (2014). http://dx.doi. org/10.3390/ma7010075.... The process of oxidizing polyacrylonitrile (PAN)-based carbon fibers converts them into an infusible and non-flammable state prior to carbonization. This represents one of the most important stages in determining the mechanical properties of the final carbon fibers, but the most commonly used methods, such as thermal treatment (200°C to 300°C), tend to waste a great deal of process time, money, and energy. There is therefore a need to develop more advanced oxidation methods for PAN precursor...
