Discharged Energy Density

The antiferroelectric-like behavior could be retained up to 675 MV m−1 with a discharged energy density of 23.3 J cm−3 because of the confinement of rigid PMMA segment onto the ferroelectric relaxation of P(VDF-TrFE-CTFE) and the high breakdown strength.

Poly Vinylidene Fluoride

CaCu 3 Ti 4 O 12 (CCTO)–poly(vinylidene fluoride (PVDF)) composites were prepared by melt blending and hot molding techniques. The addition of CCTO remarkably enhanced the dielectric properties and the thermal conductivity of PVDF composites, while the melting point of the PVDF composites (~170°C) was almost independent of the CCTO concentration. Based on the results of dielectric constant and dielectric breakdown voltage, the PVDF composite containing 40 vol.% CCTO fillers shows the optimized capacitive energy storage potential (7.81 J/cm3).
