Pervaporation of Water-Ethanol through Polyion Complex Membrane from Polyacrylonitrile and Poly(vinyl pyridine)

초록

본 연구에서는 폴리아크릴로니트릴(PAN)을 기질로 고분자 복합체막을 제조하고 투과증발공정을 이용해 물과 에탄올 이성분혼합액의 분리를 행하였다. PAN은 물과의 친화성이 높아서 고분자기질로 선택하였다. 치밀한 PAN막을 알카리 용액에서 가수분해하고 이것을 poly(4-vinyl pyridine)과 반응시켜 고분자복합체막을 제조하였다. 이 고분자복합체막은 치밀한 PAN막에 비해 유량이 약 20배 가량 증가하였다. 또한 이 막은 온도에 무관한 선택도를 유지한 반면 유량은 온도에 따라 증가하였다.

In the present work the separation of water-ethanol binary mixture through polyion complex membranes based on polyacrylonitrile(PAN) was studied using pervaporation processes. PAN was chosen as a base polymer because of its high affinity with water. It was hydrolyzed with alkaline solution followed by the reaction with poly(4-vinyl pyridine) to make polyion complex membranes. Polyion complexation of PAN with quarternized poly(4-vinyl pyridine) enhances the pervaporation flux about 20 times to that of homogeneous and dense PAN membranes. Polyion complex membranes maintain temperature-independent separation factor while the flux increases with temperatur
