Consequently, the high energy density in the dielectric polymers relies on the high Eb (>500 MV/m). In general, the energy density of a dielectric material (shaded area in Fig. 1A) is equal to the integral Ue = ∫ EdD, where E is the electric field and D is the electric displacement or charge density. Therefore, besides a high Eb, a high D ...
