| 摘 要： | 对以芭蕉芋淀粉，聚乙烯醇为原料制备的生物降解塑料Ｓｔａｒｃｈ－ＰＶＡ进行了Ｘ射线分析，并对该塑料膜的力学性能进行了研究，结果表明：随着交联剂的增加，Ｓ－Ｐ的结晶度有所则拉伸强度有所增大，延伸率出现极大值，为这获得具有较高力学性能的Ｓ－Ｐ膜材料提供了途径。

| Abstract: | Analysis of x-ray diffraction and study on mechanical properties of biodegradable S-P plastics prepared by blending and crosslinking canna edulis ker starch with the polyvinyl alcohol were carried out.The results showed that S-P films had lower crystallinity and the tensile strengh of the films were increased with increasing the amount of crosslinking agent glyoxal,and the elongation reached maximum.It provided an approach to obtain S-P film materials with higher mechanical performance. |
