聚乙烯醇共混薄膜研究进展

Research progress in poly(vinyl alcohol)blending film

从近年来聚乙烯醇(PVA)与天然高分子[淀粉、壳聚糖(CS)及蛋白质]、合成型生物降解高分子[聚乳酸(PLA)、聚己内酯(PCL)及聚乙二醇(PEG)]以及合成型不可生物降解高分子[聚苯胺(PANI)、低密度聚乙烯(PE-LD)及聚氨酯(PU)]进行共混研究角度进行分析,总结了共混薄膜的制备方法及结构性能,并介绍了PVA共混膜材料在医疗、分离、食品包装及农业领域的应用情况,最后对PVA共混薄膜未来的研究方向进行了展望。

This paper introduced the preparation methods,structure,and properties of poly(vinyl alcohol)(PVA)blending films,including PVA blends with natural polymers such as starch,chitosan,and protein,synthetic biodegradable polymers such as polylactic acid,polycaprolactone and polyethylene glycol,and synthetic non-biodegradable polymers such as polyaniline,low density polyethylene,and polyurethane. The application of PVA blending films in the fields of medical treatment,separation,food packaging,and agriculture was introduced,and their future research direction was prospected.
