| 摘 要： | 本实验用以聚乙烯醇-苯乙烯基吡啶盐的缩合物(PVA-SbQ)为光敏剂,运用紫外光辐照法以制备交联明胶-壳聚糖共混膜。用傅立叶红外、X-射线衍射方法对膜的结构进行表征,并对膜的力学性能、吸湿率、透光率性能进行研究。研究表明:PVA-SbQ分子与明胶、壳聚糖分子间存在氢键作用,光交联后,共混膜形成网状结构,有效地改善了共混膜的力学性能、吸湿性和紫外屏蔽性能等。

| Abstract: | In the experiment, photocross-linked gelatin-chitosan blend membrane was prepared by mixing the solutions of gelatin, chitosan and PVA-SbQ. Its structure was examined by means of FT-IR and XRD. The properties of membrane, such as mechanical property, hygroscopicity and light transmittance had been studied. The results show that： improved properties of the membrane such as mechanical property, hygroscopicity and UV screen property are due to some hydrogen bonding interaction between gelatin, chitosan and PVA-SbQ in the blend membrane and network of exposed membrane. |
