采用短切炭纤维对壳聚糖膜进行复合改性以提高膜的力学性能和抗湿态卷曲性。实验表明炭纤维与壳聚糖有良好的复合性，可以明显改善膜的力学性能，解决了壳聚糖膜的不可缝合性和湿态卷曲性。通过对炭纤维复合量、干燥温度、膜的柔软性等研究，找出较佳的炭纤维复合量和适宜的工艺过程 The chitosan membrane was modified by chopped carbon fiber to improve the mechanical properties of the membrane and the resistance to wet-state crimp. Experiments show that the carbon fiber and chitosan have a good compound, which can significantly improve the mechanical properties of the film to solve the chitosan film can not be stitched and wet crimp properties. Through the carbon fiber composite amount, the drying temperature, the film of softness and other research to find a better carbon fiber composite content and the appropriate process
