Abstract
수정된 Hummer`s 방법으로 제조된 산화그래핀(graphene oxide, GO)을 이용하여 PMMA와 Nylon 6,6에 분산시켜 각각 복합재료 섬유와 필름으로 제조하고 동적기계적 물성과 인장특성을 분석하였다. 동적기계적 분석과 인장 특성에서 GO-PMMA 복합재료 섬유는 GO의 효율적 기계적 물성 보강 효과를 확인 하였으나 Nylon 6,6 복합재료는 제조과정에서 사용된 포름산의 낮은 pH로 인해 산화그래핀의 분산안정성이 저하되어, 낮은 보강효율을 보임을 알 수 있었다.
In this work, we successfully fabricated graphene oxide (GO) and GO-based PMMA composite fiber and nylon films. Dynamic mechanical and tensile properties of PMMA-GO composite fiber showed that GO is efficient reinforcement for polymer matrices. However, Nylon 6,6-GO composite films showed low reinforcement efficiency in terms of dynamic mechanical and tensile properties due to the colloid instability of GO in formic acid at a low pH level.
