摘　　要：用丝素蛋白或丝素肽表面改性的聚氨酯膜表现出良好的柔韧性,它能够克服丝素膜刚而脆的弱点;由水分散型聚氨酯制备的改性膜的透气性高于疏水性聚氨酯膜;细胞培养实验结果表明:经丝素蛋白或丝素肽改性后,聚氨酯膜的生物相容性明显提高且处理效果是稳定的。Polyurethane membranes modified with silk fibroin protein(SF) and silk fibroin peptide(SP) had good flexibility. They could overcome rigid and brittle weaks of SF membrane. The water vapor permeabilities of modified membranes made from water dispersive polyurethane were superior to those of modified hydrophobic polyurethane membranes. The results of cell culture test showed that polyurethane membranes modified with SF and SP had good biological compatibility and stability.
