【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 － Ｐ Ｖ Ａ（ 简称 Ｓ－ Ｐ） 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 膜的结晶度有所降低，而拉伸强度有所增大，延伸率出现极大值．这为获得具有较高力学性能的 Ｓ－ Ｐ 膜材料提供了途径更多还原

【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.更多还原
