• 中文摘要： 聚氯乙烯/聚醯亞胺複合膜是由聚醯胺酸與聚氯乙烯在溶劑中混和,然後在啶/醋酸酐共溶液中凝結和醯亞胺化。用偏光顯微鏡觀察兩相溶液異相性,掃描式電子顯微鏡觀察複合膜的斷裂面與蝕刻表面。結果顯示,當聚醯亞胺均勻地分散在聚氯乙烯,而且呈現網狀結構時強化效果很好; 如果聚醯亞胺在聚氯乙烯中呈現顆粒狀的相分離,則薄膜變脆。
• 英文摘要： Polyvinyl chloride (PVC)/polyimide (PI) composite films were prepared from a binary solution, followed by coagulation and chemical imidization in a mixture of pyridine/acetic anhydride. The characteristics of the binary solutions were examined under the polarized optical microscope, and the morphology of the fractured surface and etched surface of the composite films was examined under scanning electron microscope. The results showed that reinforcement of PVC by the PI was achieved only when the rigid, rod-like PI chains were dispersed in the form of a polymer network in the PVC matrix. Phase separation of the PI molecules into granular particles dispersed "loosely" in the PVC matrix resulted into brittle composite films.
