摘　　要：介绍了气体分离复合膜的基本构型、制备方法及近期的发展 .阐述了制备气体分离复合膜时遇到的两个问题 :材料匹配和孔渗现象 .模拟计算了孔渗对复合膜分离性能的影响 ,并对如何防止孔渗现象的发生进行了讨论 .Recent developments in the preparation of composite membranes for gas separation are presented. Two problems which are often confronted, materials selection and pore penetration are discussed. The effect of pore penetration on membrane permeability and selectivity is simulated, and methods to prevent pore penetration are suggested.
