摘要
利用溶液共混法制备了一系列不同配比的明胶-壳聚糖共混膜,研究了壳聚糖含量对共混膜吸湿性能和力学性能的影响,采用红外光谱、透光率、扫描电镜等表征了共混膜的结构与性能。结果表明:壳聚糖的加入可改善明胶!壳聚糖共混膜的力学性能。随壳聚糖含量的增加,共混膜的吸湿率增大。在共混膜中,壳聚糖分子与明胶分子间存在较强的相互作用,二者间有良好的相容性。
A series of gelatin - chitosan composite films with different ratios of chitosan to gelatin were prepared by a solution method. The influence of chitosan content on the moisture adsorption and the mechanical properties of the composite films was studied, and the structure of the composite films was characterized by infrared spectroscopy（ IR）, optical transmittance, and scan- ning electron microscope（SEM）. The results indicate that the introduction of chitosan may improve the mechanical properties of the composite films. With increasing the chitosan content in the composite films, the moisture adsorption capacity increases. There may be a strong interaction and a good compatibility between gelatin and chitosan molecules in the composite films.
