Description
Summary:This article reviews the preparation strategies of dielectric polymers with high permittivity and low energy loss, as well as their applications in the field of energy storage and intelligent sensors. We discuss the dependence of dielectric properties of polymer composites on different types of dielectric polarizations, including interfacial polarization, orientational polarization, ionic polarization, and electronic polarization, as well as the improvement of dielectric properties by synergetic effects of multiple polarizations. Due to the difficulties of achieving both high dielectric polarization (hence high permittivity) and low dielectric loss, we focus on the energy loss mechanism of different polarization types and issues in the preparation process. We also discuss current applications and future prospects of dielectric polymers in the field.
