The Study of Chitosan and polyurethane Composite Membranes
-
摘要: 测定了甲壳胺─聚氨酯复合膜的静态和动态力学性能,并根据两单组分膜和复合膜的应力-应变行为判断复合膜界面粘合的牢固性。讨论了聚氨酯多孔膜与甲壳胺膜,以及聚氨酯预聚体与甲壳胺膜的粘合机理,并从动态力学性能的测试结果得以证实。Abstract: he composite membranes of polyurethane a0d chitosan were prepared. A new method was established with which the adherence ability of the composite membranes can be determined only from their stress and strain curves. It has been determined that the adheren
