摘　　要：本文研究了交联剂对淀粉/壳聚糖/聚乙烯醇/明胶共混膜的透光性、透气性、吸水性及保水性和力学性能的影响。结果表明：共混膜的性能与交联剂有较大关系。在交联剂用量在0%~5%的范围内,随着交联剂用量的增加,共混膜的扯断伸长率、吸水性和保水性随之降低,共混膜的拉伸强度、撕裂强度、透水气性和透光性先增加后减小。By adding some certain amount of cross-linker into the CST/CS/PVA/GEL complex to prepare CST/CS/PVA/GEL blended membrane, the properties of CST/CS/PVMGEL composite material under different amount of cross-linker were examined. The study shows, there were some strong mutual interaction forces between the properties and the amount of cross-linker. In the range of 0-5%, the elongation rate at break, the water absorbability and water-retaining property of the blended membrane decreased with the increase of the content of the crosslinker. The tensile strength, tear strength, water-retaining property and transmittance of the blended membrane increased firstly and then decreased.
