Abstract

The demand for clean water is virtually present in all modern human societies even as our society has developed increasingly more advanced and sophisticated technologies to improve human life. However, as global climate change begins to show more dramatic effects in many regions in the world, the demand for a cheap, effective way to treat wastewater or to remove harmful bacteria, microbes, viruses, and other solvents detrimental to human health has continued to remain present and remains as important as ever. Well-established synthetic membranes composed of polyaniline (PANI), polyvinylidene fluoride (PVDF), and others have been extensively studied to gather information regarding the characteristics and performance of the membrane, but recent studies have shown that making these synthetic membranes conductive to electrical current by doping the membrane with another material or incorporating conductive materials onto the surface of the membrane, such as allotropes of carbon, have shown to increase the performance of these membranes by allowing the adjustability of pore size, improving antifouling and making the antibacterial property better. In this review, modern electrically conductive membranes are compared to conventional membranes and their performance improvements under electric fields are discussed, as well as their potential in water filtration and wastewater treatment applications.

깨끗한 물에 대한 수요는 우리 사회가 인간의 삶을 개선하기 위해 점점 더 진보되고 수준 높은 기술을 개발함에도 불구하고 모든 현대 사회에 존재한다. 그러나 지구 기후 변화가 전 세계 여러 지역에서 더욱 극적인 영향을 미치기 시작하면서 폐수를 처리하거나 인체 건강에 해로운 박테리아, 미생물, 바이러스 및 기타 용매를 제거하기 위해 저렴하고 효과적인 방법에 대한 요구가 계속되고 있고 그 어느 때보다 중요하다. 폴리아닐린(PANI), 폴리(비닐리덴 플루오라이드)(PVDF) 등으로 구성되어 있는 합성막은 잘 구축되어 있고 막의 특성과 성능에 관한 정보를 수집하기 위해 광범위하게 연구되었지만 최근 연구에 따르면 이러한 합성막을 전류에 전도성 있게 만드는 것으로 나타났다. 다른 물질로 막을 도핑하거나 탄소 동소체와 같은 전도성 물질을 막 표면에 통합함으로써 기공 크기의 조정 가능성, 더 나은 방오성과 항균성을 허용함으로써 이러한 막의 성능을 증가시키는 것으로 나타났다. 본 총설에서는 현대의 전기 전도성 막을 기존 막과 비교하고 전기장 하에서의 성능 향상과 물여과 및 폐수 처리 응용 분야에서의 잠재력에 대해 논의한다.
