| Abstract: | The porous protein blend film of gelatin and domestic silk fibroin was prepared by freeze drying. The effects of the cross linking agent, blend ratio and freeze temperature on the structure and properties of film were investigated. The results indicated that the porous blend film was cross linked obviously as a function of glutaraldehyde, silk fibroin and gelatin in the film were compatible and the structure of protein was mainly amorphous, and that the tensile properties of porous silk fibroin film was improved by blending with gelatin. |
