英文摘要：

Polymer-based composite dielectric materials with high energy density have potential application in the ca- pacitor field, and many researches focus on ferroelectric materials due to their high permittivity. We discussed the energy storage theory, electric polarization characteristics, charge-discharge efficiency of ferroelectric polymer-based nanocom- posite dielectrics that are closely related with energy density, analyzed the energy storage mechanism, and proposed the development prospection. Moreover, we further investigated the main fabrication strategies including surface modifica- tions of nanofillers, ferroelectric polymer-based composites of multi-phase blends, managements of multi-layer structure, the resultant promoted dielectric properties, as well as high energy density.
