Abstract
Silver carp skin collagen/polysaccharide blend films were prepared by solvent-casting method with silver carp skin collagen and polysaccharide. Tensile strength (TS) , percentage elongation at break (EAB) , water vapor permeability (WVP) , light transmittance and water solubility were determined. The result showed that collagen/chitosan blend film had the best property, and the optimal ratio of collagen and chitosan for preparation blend film was 3∶1 (w/w) . At this time, the mechanical property of the blend film was the best, TS was 35.47MPa, EAB was 25.87%. The WVP, light transmittance and water solubility of the blend film were improved. FTIR-ATR, X-RD and SEM analysis revealed that there were strong interactions and good compatibility between collagen and chitosan.
