摘　　要：用预聚体接枝 -扩链法制备了丝素蛋白改性聚氨酯膜 ,考察了反应温度、时间和湿度等因素对膜的力学性能的影响。结果表明改性聚氨酯膜具有良好的柔韧性 ,其力学性能明显优于纯丝素膜。The polyurethane membranes modified with silk fibroin (PU-SF membranes) were obtained by the grafter and chain extender of prepolymer. The influences of temperature、time and moisture on the mechanic performances of membranes were discussed. The results indicated that PU-SF membranes had good flexibility and their mechanic performances were superior to those of silk fibroin membranes.
