Blend Films of Chitosan-Gelatin

Chitosan\|gelatin blend films were prepared successfully by solution method, and characterized by FT\|IR, X\|ray diffraction, SEM, optical transmittance, percent water absorption and measurements of mechanical properties. The results indicated there was some strong interaction and good compatibility between chitosan and gelatin molecule in the blend films. The introduction of chitosan was beneficial to decrease the percent water absorption,improve mechanical properties of gelatin. \;
