Abstract

We have been fabricated Thin-walled carbon nanotubes (TWNTs)/amine epoxy additives composite using Eco-friendly solvent system such as supercritical process and dry mixed process. TWNTs/amine epoxy additives composite has used as a curing agent for urethane based bisphenol A type epoxy resin. The thermo-mechanical property of the epoxy resin cured by TWNTs/amine epoxy additives composite is characterized by dynamic mechanical analysis(DMA) and dispersability of the nanotubes in the epoxy matrix is also confirmed by scanning electron microscope(SEM). As a results, the epoxy resin cured by TWNTs/amine epoxy additives composite with supercritical process shows enhanced dispersability of the TWNTs in the matrix and thermo-mechanical property when compare to dry mixed process.

본 연구에서는, 유기용매를 사용하지 않는 친 환경적인 건식 공정과 초임계 공정을 이용한 Thin-multiwalled carbon nanotube (TWNTs)/아민계 에폭시 첨가제의 복합체 제조에 관하여 연구를 하였다. 제조된 TWNTs/아민계 에폭시 첨가제의 복합체는 우레탄기반의 비스페놀 A 타입의 에폭시 레진의 경화제로 사용하였다. TWNTs/아민계 에폭시 첨가제의 복합체를 경화제로 사용하여 제조된 에폭시 레진의 열적 성질을 Dynamic mechanical analysis (DMA)를 이용하여 분석 하였으며, 메트릭스상의 carbon nanotube의 높은 분산성은 SEM을 통하여 확인 하였다. 그 결과, 초임계 공정을 이용하여 제조된 에폭시 레진의 열적 성질과 매트릭스내의 carbon nanotube 분산성이 건식 공정을 사용 하였을 때 보다 더욱 증가된 결과를 확인 할 수 있었다.
