| Abstract: | 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. |
| Keywords: | silk fibroin polyurethane modification biological compatibility |
