Preparation and Mechanical Property Testing of Chitosan-gelatin Blend Film

The chitosan-gelatin blend film was prepared by blending method,and the mechanical properties of the chitosan-gelatin blend film were tested.It was shown by research that the mechanical strength of chitosan-gelatin blend film could be changed by the mixing proportion of chitosan-gelatin blend film,whose modulus of elasticity and tensile failure stress were gradually decreased with the increase in content of gelatin,the tensile-strength was minimum when the volume ration between chitosan solution and gelatin blend is 4∶6.The elongation at break was maximum when the volume ration between chitosan and gelatin was 6∶4.
