通过齐聚物反应制备高储能聚酰亚胺材料

The project is proposed to prepare a kind of block copolymer, copper phthalocyanine/polyimide [P (CuPc)4/PI], with colossal dielectric constant, high breakdown strength, low dielectric loss, heat resistance and high energy-storage density and other characteristics via a polycondensation between amino-capped polyimide (PI) oligomers and carboxyl group-rich copper phthalocyanine oligomers [P (CuPc) 4 (COOH) 16]. It was proposed to explore the effect of the unit structure, composition and molecular weight of the PI block part on the performance of such a block copolymer, and to establish a structure-activity relationship between PI block part and the block copolymer so that the characteristics of the block copolymer could be tailored randomly via synthesis technology. The purpose of this research is in order to meet the urgent needs of the modernization of our country on the high-performance new materials.
