摘要

超临界二氧化碳做非溶剂制备聚合物微孔膜是一个新的研究热点，具有传质系数高、聚合物膜干燥速度快且不破坏结构、溶剂容易回收、CO

可循环使用、CO

的低毒性与环境友好性等特点。本文介绍采用超临界CO

制备聚合物微孔膜的热力学及动力学原理，重点介绍近年来采用此技术制备微孔膜的研究成果，如以聚苯乙烯（PS）、聚丙烯腈（PAN）、聚醚砜（PES）等为基体的微孔聚合物膜。

Abstract

The use of supercritical CO

as non-solvent has been attracting attentions in the formation of polymer microporous membrane.Advantages of this method are high mass transport coefficient

rapid drying of the polymer membrane without collapse of the structure

easy recovery of solvent and recycling of CO

and low toxicity of CO

.The thermodynamics and kinetics theory in the preparation process were presented.The studies on polystyrene

polyacrylonitrile

polyethersulfone microporous membrane etc were mainly introduced.
