Abstract

Research on polymer-based dielectric materials with low energy loss and high power density for dielectric capacitors can promote the development of advanced energy storage devices and effectively solve energy storage problems. In recent years, all-organic polymer dielectrics have received extensive attention due to the excellent properties and have shown broad development prospects in the energy storage industry. Compared to polymer inorganic composites with bad processability, all-organic dielectrics have proven to be a more suitable option for low-cost and large-scale production. This review summarizes the phased achievements of traditional all-organic polymer dielectrics and the recent progress in polymer modification technology. Meanwhile, the energy storage theory of dielectrics, such as energy storage parameters, polarization mechanisms, breakdown mechanisms, and conduction mechanisms, is thoroughly reviewed. Finally, this paper identifies the existing problems of all-organic polymer dielectric materials and proposes feasible solutions and possible future research priorities.
