摘要: 乙烯-乙烯醇共聚物(EVAL)是一种带有功能化基团的亲水性微孔膜材料,在生物学和生物医学的应用中受到广泛关注。介绍了浸没沉淀法制备EVAL微孔膜的成膜机理、成膜过程的影响因素(包括EVAL初始浓度、添加剂、凝固浴和溶剂蒸发等),综述了其研究进展,并指出其应用前景。

Abstract: Poly(ethylene-co-vinyl alcohol)(EVAL) with functional groups has gained more attention in recent years,especially in biological and biomedical applications. This article introduces the formation mechanism of EVAL membranes via immersion precipitation and the effects of the initial concentration of EVAL,additives,non-solvents,coagulation temperature and evaporation condition on the membrane properties. The development of EVAL microporous membrane is also summarized.
