Study on the Blend Film Prepared by Chitosan and Gelatin

Abstract:

The viscosities of blend solution mixed with various concentration of chitosan and gelatin were investigated and the properties of the blend films prepared by gelatin and chitosan were studied by FT–IR, DSC and SEM in this paper. The results indicated that the viscosity of blend systems increased with the concentration increasing of chitosan, and that of mixed solution decreased with the concentration increasing of gelatin; there existed strong interactions between chitosan and gelatin molecular chains through hydrogen bond formation and chemical reaction; the surface of blend film had a relatively uniform and compact surface and the thermal stable of blend film was higher than pure gelatin film.
