Abstract

유 무기 혼성 막의 계열은 티타니움 디옥사이드 나노파티클 함량의 체계적인 변화에 의해 조제된다. 유 무기 혼성 막의 수분함량, 메탄올 투과도와 전자 전도 특성은 무기 산화물의 함량의 기능에 따라 연구된다. 그 결과 망상구조의 무기 산화물은 전자 전도 특성과 수분함량의 감소를 보였다. 또한 무기 산화물의 함량이 증가할수록 메탄올 투과도도 감소함을 나타내었다. 형태학적인 관점에서 막은 폴리머 기반과 무기영역 사이에 균일하고 잘 점착됨을 보여준다. 혼성막의 특성은 나피온막과 비교 실험되었다. A series of inorganic-organic hybrid membranes were prepared with a systematic variation of titanium dioxide nano particles content. Their liquid uptake, methanol permeability and proton conductivity as a function of inorganic oxide content were investigated. The results obtained show that the inorganic oxide network decreases the proton conductivity and liquid uptake. It is also found that increase in inorganic oxide content leads to decrease of methanol permeability. In terms of the morphology, membranes are homogeneous and exhibit a good adhesion between inorganic domains and the polymer matrix. The properties of the composite membranes are compared with the standard nafion membrane.
