Abstract

Nano materials having large surface area, uniform dimensions or pores can be utilized in various membrane applications. Recently, many studies have been focused on the application of nano materials and nano technologies in membrane applications by the help of the discovery and development of nano technologies. in terms of mass transport channels or functional modification. However, there have been several technological limitations for commercialization. Nano materials and nano technologies can improve 1) permeability, selectivity, 2) mechanical, chemical, thermal stability or fouling tolerance of conventional membranes and even 3) introduce new functionalities such as specific affinity and reactivity.

나노 소재는 표면적이 매우 크고 크기나 기공이 균일하여 분리막에서 물질 전달 통로나 특수한 기능성을 갖게 하는 소재로 이용이 가능하다. 그러나 나노 소재 및 나노 기술을 기반으로 한 분리막의 상용화를 위한 여러 가지 기술적인 한계가 존재하며 최근 나노 소재 및 제조 기술이 발전하고 다양해짐에 따라 분리막에 나노 소재 및 기술을 활용하려는 연구가 많이 진행되고 있다. 나노 소재 및 기술을 활용하는 경우 기존 분리막의 투과도 및 선택도를 크게 높일 수 있으며 열적, 화학적, 기계적 안정성 및 내오염성을 향상시키거나 기능성 소재를 활용하여 분리막에 새로운 기능을 부여할 수 있다.
