摘要
聚乙烯醇(PVA)是一种合成的可生物降解高分子材料,分子中含有大量的羟基,使其耐水性、加工性等需要改善。本文对PVA常用的与多糖、无机盐和其他无机物的共混、交联、热处理等方法进行了综述,并简要介绍了PVA在包装、反渗透、质子交换膜等领域的一些应用情况,最后对PVA的后续研究进行了展望。
Polyvinyl alcohol(PVA)is a kind of synthetic biodegradable macro-molecule material which contains a large number of hydroxyl groups.It is necessary to improve its water resistance,mechanical performance and thermal behavior,etc.The typical methods such as blending,crosslinking and heat treatment for modification of PVA with polysaccharid,inorganic salts and other inorganic substance.The applications of PVA in packaging,reverse osmosis film and proton exchange membrane,etc.are introduced.Moreover,the prospect of PVA is given
