초록

나노 소재는 표면적이 매우 크고 크기나 기공이 균일하여 분리막에서 물질 전달통로나 특수한 기능성을 갖게 하는 소재로 이용이 가능하다. 그중에서도, 그래핀, 그래핀 옥사이드 및 탄소나노튜브와 같은 나노탄소 구조체에 대한 연구가 활발히 이루어지고 있다. 일차원 구조를 갖는 탄소나노튜브의 경우 우수한 열적, 화학적 및 기계적 성질을 가지고 있으나, 기존 연구에서는 주로 고분자와 혼합하여 기계적 물성을 강화하는 복합소재로서 사용됐으며, 응용분야의 한계를 가지고 있었다. 본 연구에서는 폴리 에틸렌 글리콜 다이아크릴레이트(PEGDA) 고분자 내에 개질된 탄소나노튜브를 혼합하여, 기체 분리막에서의 투과도 및 선택도의 변화를 관찰하였다.

Nanomaterials having large surface area, uniform dimensions or pores can be utilized in various membrane applications Amongst them, many studies have been focused on nanocarbon materials: graphene, graphene oxide and carbon nanotubes. Carbon nanotubes, one-dimensional structure, have excellent characteristics in thermal, chemical and mechanical strength properties. However, carbon nanotubes was mainly used to reinforce mechanical properties of polymer materials in previous applications. In contrast to previous studies, we focused on modified carbon nanotubes/polyethylene glycol diacrylate (PEGDA) composite membrane preparation for improvement of permeability and selectivity on gas separation.
