Abstract: The chitosan and gelatin blends (CGB) were prepared with the gelatin content from 0% to 100%.The compatibility of the blends was discussed by calculating the interaction parameter and by detecting the phase structure with UV VI spectrum and PCM microscopy.As a result the minus interaction parameter and the homogenous structure certified the compatibleness of chitosan and gelatin.The mechanical properties of CGB were also determined.CGB film showed a plastics like stress strain curve in dry state and a rubber like stress strain curve in wet state.The tensile stress of CGB decreased with the increasing of gelatin content;the elongation at break decreased with the increasing of gelatin content in dry state but they were higher then that of both chitosan and gelatin except from CGB 90 in wet state.Infrared spectra showed that chitosan and gelatin could form a complex by the reaction of —NH 2 in chitosan and —COOH in gelatin.
