聚乙烯醇基生物可降解复合材料的研究进展

摘要

结合国内外近年来关于聚乙烯醇可降解材料的相关研究,本文就聚乙烯醇的性能、降解机理以及其复合材料的可降解研究进展作以介绍.结果显示,聚乙烯醇中添加淀粉、纤维素、壳聚糖、聚乳酸、大豆蛋白等生物可降解材料能够明显提高聚乙烯醇的降解速率,但聚乙烯醇基生物可降解材料在实践应用中仍然有一定的难度.%Purpose Research on the progress of biodegradable composites based on polyvinyl alcohol. Method Combine the related research both at home and abroad in recent years about PVA biodegradable materials. Mainly introduce the performance of polyvinyl alcohol and degradation mechanism of biodegradable. Result Add the biodegradable materials such as starch, cellulose and chitosan, poly (lactic acid) (PLA), soybean protein, the degradation rate of polyvinyl alcohol can be significantly improved. Conclusion PVA biodegradable materials still have certain problem in the application, and improve the water resistance and the degradability will expand its application.
