Abstract

For selectively permeable membrane based on cellulose acetate butyrate (CAB) and polyethyleneimine (PEI) with water vapor transportability and DMMP protective performance, we intended to improve protective performance of the membrane against CEES using several additives. Results showed that CAB/PEI membranes possessed performance with good water vapor permeation (${\geq}1,800g/m^2/day$) and enhanced protective capability against CEES contamination ($7.1{\sim}11.5{\mu}g/cm^2{\cdot}day$). Of these membranes, the membrane containing $Ag^+$ ion and ionic exchange resin showed the best protective performance. And, we identified that the CAB/PEI membranes show excellent protection against aerosols with various particle sizes ($0.005{\sim}3{\mu}m$) simulating biological agents.

수증기 투과성과 DMMP 방호성능을 가지는 cellulose acetate butyrate (CAB)/polyethyleneimine (PEI) 기반의 선택투과막에 대해 여러가지 첨가제를 적용하여 CEES에 대한 방호성능 개선을 시도하였다. 시험결과, CAB/PEI 기반의 선택투과막은 수증기 투과성은 그대로 유지하면서(${\geq}1,800g/m^2/day$), CEES에 대한 방호성능의 개선을 보여주었다($7.1{\sim}11.5{\mu}g/cm^2{\cdot}24hr$). 이 중, $Ag^+$ 이온과 이온교환수지 혼합물을 포함한 CAB/PEI 선택투과막에서 가장 우수한 방호성능을 확보하였다. 그리고 시험한 모든 선택투과막은 생물학작용제를 모사할 수 있는 다양한 크기의 에어로졸 입자($0.005{\sim}3{\mu}m$)에 대해서도 방호성능을 가짐을 확인하였다.
