壳聚糖-明胶共混膜

用溶液共混法成功地制备了壳聚糖与明胶共混膜，并用红外光谱， Ｘ 射线衍射，扫描电镜，透光率，吸水率及力学性能测试对共混膜进行了表征结果表明，共混膜中壳聚糖分子与明胶分子间存在强的相互作用及良好的相容性，壳聚糖的引入有利于减小明胶的吸水率，改善其力学性能

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.
