Abstract
本发明提供一种可修复且可回收的聚酰亚胺高分子树脂及其修复与回收方法。可修复且可回收的聚酰亚胺高分子树脂包含如式(I)所示的一化学结构单元:式(I)中各符号如说明书中所定义。前述的修复方法于一修复温度下,对可修复且可回收的聚酰亚胺高分子树脂以一修复方式进行修复。前述的回收方法将可修复且可回收的聚酰亚胺高分子树脂溶解于一二乙烯三胺溶液中,再进行涂布与烘烤成膜,以形成一回收聚酰亚胺膜。借此,前述的可修复且可回收的聚酰亚胺高分子树脂具有刚硬、抗化、耐热、可修复且可回收的特性。
The invention provides repairable and recoverable polyimide polymer resin and a repairing and recovering method thereof. The repairable and recoverable polyimide polymer resin comprises a chemical structural unit as shown in a formula (I): # imgabs0 #, wherein each symbol in the formula (I) is defined in the specification. The repairing method is used for repairing the repairable and recoverable polyimide polymer resin in a repairing manner at a repairing temperature. According to the recovery method, the repairable and recoverable polyimide polymer resin is dissolved in a diethylenetriamine solution, and then coating and baking film forming are carried out to form a recovered polyimide film. Therefore, the repairable and recoverable polyimide polymer resin has the characteristics of rigidity, chemical resistance, heat resistance, repairability and recoverability.
