| 摘 要： | 用不同性能地壳聚糖为膜材料制备壳聚糖膜，通过体外酸解，酶解试验及动物体内植入试验研究其降解。试验结果表明，壳聚糖是一种可生物降解性膜材料，壳聚糖膜的降解性与其脱乙酰度，介质酸性强弱及溶菌酶等因素有关。壳聚糖膜在动物体内降解比较缓慢，２０天约降解８．２％。

| Abstract: | Chitosan films were prepared with raw materials. In vivo biodegradation and in vitro degradation of chitosan films were studied. The results indicate that Chitosan is a biodegradable material, and the degradability of films depends on the degree of deacetylation of chitosan, medium pH and lysozyme; in vivo biodegradation of chitosan films is slow. |

| Keywords: | Chitosan Chitosan film Film degradation Lysozyme Biodegradability |
