改善聚乙烯醇薄膜耐水性的研究进展
Research progress on improving water-resistance of poly(vinyl alcohol) film
摘要
Abstract
Poly(vinyl alcohol) (PVA) film has the disadvantage of absorbing water easily to swell which then weakens its gas barrier and mechanical properties,so it is not suitable for the applications requiring high gas barrier property and mechanical properties and its water-resistance needs to be improved.In this article,four methods for evaluating the water resistance of PVA film and the influence of alcoholysis degree and molecular weight of PVA resin on its water resistance are introduced firstly.Then,the mechanisms and research progress of four approaches for improving PVA film's water resistance (chemical crosslinking,physical crosslinking,inorganic nanomaterial composite and polymer blending methods) are reviewed intensively,and their advantages and drawbacks are compared.The applications of water resistant PVA film in separation and purification,package,polaroid and biomedicine are introduced.Finally,the outlook of water resistant PVA film is given.The development of novel green and environment-friendly method to improve its water resistance further and the extension of its application range are the research subjects deserving more attention.关键词
