Abstract

We fabricated several composite membranes with selectively permeable performance designed to facilitate water vapor transport and resist DMMP vapor permeation. Materials for selective permeable membrane were based on polyvinyl alcohol and functional polymer containing basic functional group. With these materials, we characterized selectively permeable performance to identify next-generation material with chemical-biological protective capability. Results showed that polyvinyl alcohol (PVA)/polyethyleneimine (PEI) materials possessed performance with superior water vapor permeation ($2,200{\sim}2,900g/m^2/day$) and protective capability against DMMP vapor ($47g/m^2/day$).

수증기 투과는 용이하게 하면서 Dimethyl methylphosphonate (DMMP)에 대한 방호성능을 부여하는 선택투과성능을 가지도록 고안된 몇가지 복합막을 제조하였다. 선택투과막 재료는 폴리비닐알코올 고분자를 기반으로 염기성 작용기를 가지는 기능성 고분자를 포함하도록 하였다. 이들 재료를 사용하여 화생방호성능을 보유한 차세대 소재로서의 가능성을 확인하기 위하여 선택투과능을 평가하였다. 시험한 결과, 폴리비닐알코올/폴리에틸렌이민 소재가 우수한 수증기 투과성능($2,200{\sim}2,900g/m^2/day$) 및 DMMP 증기 방호성능($47g/m^2/day$)을 가지는 것을 확인하였다.
