In order to improve the energy storage properties of polyetherimide (PEI) films, the aminated metal-organic framework (ZIF-8-NH2) was loaded on the surface of graphene oxide (GO) by electrostatic action, and then self-assembled to PEI film surface by intermolecular hydrogen bonding. After annealing, GO was reduced to reduced graphene oxide (rGO), and PEI-rGO@ZIF-8 composite films were obtained, and the effect of the ratios of rGO to ZIF-8-NH2 on the energy storage performance of PEI composite films were investigated. The results show that the discharge energy density of PEI-rGO@ZIF-8 (1∶15) composite film can reach 8.24 J/cm3 under the electric field of 680 MV/m, and maintain a high charge-discharge efficiency of 88.36%, showing excellent energy storage performance.
