| 摘 要： | 根据壳聚糖与明胶的相容性,制备了壳聚糖膜、壳聚糖/明胶共混膜,研究了增加明胶含量对膜的强度、拉伸位移、溶出率、吸水率的影响.采用FT-IR谱图和XRD谱图分析,研究了膜的微观结构,探讨了共混体系中壳聚糖与明胶的相容性以及分子间的相互作用.当明胶含量在30%时,改性壳聚糖膜的抗拉强度达到最大值;在10%时,它的拉伸断裂伸长达到最大值;20%时,改性膜的吸水率达到最低;改性膜的溶出率则随着明胶含量的增加而增大.

| Abstract: | According to the compatibility of chitosan and gelatin,chitosan film and chitosan/gelatin blend film were prepared.The influence of gelatin content increase on the film strength,the tensile displacement,dissolution rate,and water absorption rate was investigated.The microscopic structure of film was analyzed by IR spectrum and X-ray diffraction.The compatibility of chitosan with gelatin and the interaction of the intermolecules of the complex system were discussed.The tensile strength and the tensile elongation of modified chitosan film reached the maximum value when the gelatin content was 30% and 10%,respectivley.The water absorption rate of the modified film decreased minimum when the gelatin content was 20%.And the dissolution rate increased with the gelatin content increasing. |
