摘　　要：综述了近年来水溶性聚乙烯醇(PVA)薄膜的制备工艺进展,介绍了其在共聚改性、共混改性、复合改性方面的研究进展,以及在制备工艺、改性方法上的优缺点。共混改性可简单通过材料混合显著提高性能;与共混改性相比,共聚改性的组分混合较为均匀,但是条件较难控制;复合改性可以综合共聚改性和共混改性的优点。This article describes the progress in the preparation process of water-soluble polyvinyl alcohol(PVA)films,including copolymerized modification,blending modification,and composite modification.The advantages and disadvantages of the preparation processes and modification methods are introduced as well.The properties of the films are improved by mixing materials via blending modification.The components produced by copolymerized modification are more uniform than those by blending modification,while whose conditions are difficult to control.The composite modification integrates the advantages of copolymerized and blending modification.
