摘要

非极性及弱极性的结晶高聚物常温下无合适的良溶剂，所以无法使用传统的非溶剂致相分离法制取微孔膜，而近年来发展的热致相分离法解决了这一问题。研究发现聚乙烯、聚丙烯、乙烯-乙烯醇共聚物、乙烯-丙烯酸共聚物、聚( 4-甲基-1-戊烯) 等聚烯烃是可采用热致相分离法制备微孔膜的材料。本文综述了近年来在热致相分离法制备聚烯烃微孔膜方面的研究进展，重点介绍各种制膜材料( 聚合物、稀释剂、萃取剂和助剂) 与各种制膜工艺对制得的聚烯烃微孔膜孔径、膜通量和非对称结构等的影响。

Abstract

Because it is difficult to find good solvents for non-polar crystallizable polymer at room temperature

the microporous membranes cannot be made by non-solvent induced phase separation .But a recently developed method of thermally induced phase separation has resolved the question .Researches showed that some polyolefins such as polypropylene ( PP)

polyethylene ( PE)

poly ( ethylene-co-vinyl alcohol) EVAL

ethylene-acrylic acid coplymer( EAA) and poly( 4-methyl-1-pentene) ( TPX) are materials of making microporous through thermally induced phase separation .This article reviews the research development and focuses on the effects of different kinds of materials ( polymer

diluents

extroctants and additive agents) on microporous membrane' s pore diameter

transfer rate and asymmetric structure .
