摘　　要：采用均苯型聚酰亚胺做基体树脂、亚磷酸三苯酯(TPP)做脱模剂,用直接流延法制备了聚酰亚胺/纳米Al2O3复合薄膜;探讨了脱模剂用量对复合薄膜性能的影响。结果表明,随TPP用量的增加,复合薄膜的脱模效果逐渐变好,但复合薄膜的拉伸强度、断裂伸长率等力学性能和电气强度均呈下降趋势。Polyimide/nano-Al2O3 composite films were prepared by using polypyromellitimide as matrix resin, triphenyl phosphite （TPP） as stripping agent with direct doping method. The effects of stripping agent on the properties of polyimide/nano-Al2O3 composite films were discussed. The results showed that with the increase of content of TPP, the stripping effect tended to get better, but the mechanical properties such as tensile strength, and elongation at the break decreased, and electrical strength of composite films became poorer.
