Summary: A series of cross-linked polyimide films with outstanding dielectric properties and high temperature energy storage property were prepared by introducing the end-capping agent, norbornene dioic anhydride. The cross-linked structure greatly reduces the dielectric loss and improves the electrical insulation properties of the films. The films exhibit a maximum energy storage density of 9.4 J/cm3 and maintain high energy storage density and efficiency at elevated temperatures.

Summary: We successfully enhance the dielectric breakdown strength and electrostatic energy storage density of polymer-based materials by introducing heterostructure nanoparticles into the matrix. The special electrical rectification effect of these nanoparticles captures and confines charge carriers, resulting in suppressed leakage current and increased dielectric displacement and charge-discharge efficiency. The introduced heterojunction of ZnO-ZnS nanoparticles enables high energy storage performance, even at high temperatures and over long cycles.

Summary: Introducing conductive nanoparticles into ferroelectric polymers significantly enhances the permittivity of composites, making them promising for energy storage devices. However, the breakdown strength of such composites is often reduced, posing limitations for high-performance applications. By designing Fe3O4@BaTiO3 core-shell nanoparticle/PVDF nanocomposites, moderate breakdown strength and high energy storage performance are achieved through a voltage dispersion layer mechanism.

Summary: This paper presents a theoretical approach to study the effective dielectric permittivity of nanocomposites, considering the shape and orientation of nanoinclusions. The response of inclusions to an external electric field is investigated using the point dipole approximation and Green's function approach. The local field in nanocomposites is found to be influenced by the dipole field reflected from the capacitor electrodes.
