| 摘 要： | 研究了聚乙烯醇与Ｃｕ＾２＋的配位反应，用红外，紫外－可见光谱，Ｘ－ｒａｙ及ＤＳＣ等分析探讨了配位反应对ＰＶＡ的结晶度及生物降解性的影响。结果表明，ＰＶＡ－Ｃｕ＾２＋的配位反应降低了ＰＶＡ的结晶度，但新化学键的引入使ＰＶＡ薄膜的抗生物降解性增强。

| Abstract: | This paper presents the coordination between polyvinyl alcohol(PVA) and Cu 2+ . The effect of coordination on crystallinity of PVA was determined by FT IR, UV visible spectrum, X ray analysis and DSC. The biodegradation of PVA Cu 2+ film was studied. It shows that the coordination can enhance the bioresistance of PVA film although it decreases the crystallinity of PVA. |
