| 摘 要： | 以淀粉（Ｓｔａｒｃｈ）、聚乙烯醇（ＰＶＡ）为原料制备了共混交联塑料薄膜（Ｓ－Ｐ），采用ＡＳＴＭ法与培养皿法测定Ｓ－Ｐ膜材料的生物降解性能。实验结果表明：以该材料制成的农膜可被微生物降解，其降解速率随淀粉含量的增加而增加，随交联剂含量的增加而降低。 |
| 关 键 词： | 塑料 生物降解 淀粉 S－P型 性能 |

| Abstract: | A S-P plastic film was prepared by blending and crosslinking starch ( ST ) with polyvinyl alcohol ( PVA ),and the biodegradability of the film was determined with ASTM and Quantitative Petri Dish methods. The results showed that the film could be biodegraded by microbe. The speed of biodegradation increased with the increasing could amount of starch, and decreased with the increasing the amount of crosslinking the agent formaldehyde. |
| Keywords: | plastics biodegradation starch determination |
