Abstract
The continuous miniaturization of electronic devices and electric equipment requires high energy-storable dielectric capacitors. Therefore, seeking dielectric materials with high power density and high energy density becomes more urgent for ensuring their reliability. However, the contradiction between the increase in the dielectric constant and breakdown strength severely limits the sustainable increase in the energy density of polymer dielectrics. Here, recent advances in high dielectric and energy storage polymer dielectrics will be introduced. Polymer structure is an important factor in determining dielectric properties and energy storage characteristics of polymers, while the relationship between them is still unclear, which hinders the design of high energy-storable polymers. Our emphasis will be given to how to tailor the polymer structures for high dielectric and energy-storable polymer dielectrics. The effect of the polymer structures on the polarization and charge transport characteristics are also carefully discussed for further understanding the structure-property relationship. Finally, the follow-up research is briefly introduced. We intend that this work will help academics and industry toward high energy-storable polymer capacitors.
