Preparation of PEI dielectric composite films and study on their energy storage performance
Abstract
Abstract The energy storage industry is developing rapidly, and traditional polyetherimide (PEI) dielectric films can no longer meet current demands. Therefore, the development of dielectric energy storage films with higher efficiency and power is urgently required. In this paper, PCN-224 was prepared using zirconium oxychloride octahydrate (ZrOCl 2 ·8H2O) and 5, 10, 15, 20-tetra (4-carboxyphenyl) porphyrin (H 2 TCPP) as raw materials. Subsequently, PCN-224 MOF/PEI composite films were prepared via a casting method and tested. To achieve a higher energy storage density, the optimal process ratio and other key parameters were determined. This study verified the feasibility of this method and provided novel ideas for subsequent research and development.
