摘　　要：以天然高分子材料壳聚糖为原料,采用流延法制备了壳聚糖膜。研究了N-乙酰化和交联壳聚糖膜的制备方法及性能特性等。通过FTIR、XRD和SEM方法表征结构,并测试了力学性能。试验结果表明交联和乙酰化可以增加壳聚糖膜的拉伸强度提高膜的性能。Take chitosan as the raw material to prepare the chitosan membrane,and the membranes were characterized by FTIR,X-ray diffraction and SEM.Use glutaraldehyde as a cross linking agent to get the crosslinked chitosan membrane.Their preparation method and mechanical properties were studied and measured.The result of the experiment shows that acetylation and crosslinking can improve the tensile strength of the membrane.
