Abstract
Abstract Ba(Fe0.5Ta0.5)O3/poly(vinylidene fiuoride) (BFT/PVDF) bulk nanocomposites are fabricated via a physical mixing method followed by heat treatment. The BFT particles in nanocomposites exhibit excellent dispersion and compatibility. The enhanced dielectric constant and loss have been obtained, which is attributed to the giant dielectric constant of BFT and the enhanced interfacial polarization. An energy storage density up to 2.18 J/cm3 is achieved in the nanocomposites with BFT filler content of 2 vol% at a low electric field of 500 kV/cm. This value of energy storage density at low electric field is much higher than other polymer-based bulk nanocomposites. It is believed that the study may provide a new direction to enhance the energy storage density of ceramic/polymer nanocomposites.
