摘　　要：研究干燥温度对壳聚糖-明胶复合膜性能的影响。通过对复合膜拉伸强度、断裂伸长率、吸水率、透水气率和透光率性能的检测表明,干燥温度对膜的物理性能产生了显著的影响。综合各种指标,在50℃条件下干燥,膜的综合性能最好。In this paper, the effect of drying temperature on chitosan/glutin composite films was investigated. The tests of properties such as tensile strength, elongation rate, water absorption, water vapor permeability values and transparence revealed that drying temperature was one of the important factors that affected the properties of chitosan/glutin composite films. It was founded that when the drying temperature was 50 ℃, the experimental results showed that the films had the best properties.
