| 摘 要： | 以3,3’,4,4’-二苯甲醚四甲酸酐(ODPA)为二酐单体,采用等摩尔分数的9,9’-二(4-氨基苯基)芴(BAFL)和3,4’-二氨基二苯醚(3,4’-ODA)、4,4’-二氨基二苯醚(4,4-’ODA)、1,3-双(4-氨基苯氧基)苯(1,3,4-APB)或1,4-二(4’-氨基苯氧基)苯(1,4,4-’APB)分别共聚制备含芴共聚聚酰亚胺(CPI)薄膜。对CPI薄膜进行FT-IR,DMTA,TGA和拉伸性能的测试。采用部分酰亚胺化的CPI薄膜与不锈钢黏结,制备单搭接黏结件,测试其室温及高温拉伸剪切强度,进而比较其黏结性能。结果表明,含芴CPI薄膜具有较好的力学性能和热性能。BAFL,3,4’-ODA与ODPA共聚所得CPI薄膜的黏结性能最好,室温拉伸剪切强度达到19.2MPa,250℃仍然可达13.4MPa。
