A hybrid nanoparticle, consisting of BaTiO3 nanoparticles tightly embedded in bronnitride (BN) nanosheets, has been fabricated based on a daring supposition that BN may act as a host to incorporate ferroelectric nanoparticles to improve insulation and polarization under a high electric field. Using the hybrids as fillers in poly(vinylidene fluoride) (PVDF) composites, a high electric breakdown strength (E-b approximate to 580 kV/mm), which is 1.76 times of the PVDF film, is obtained when the filler content is 5 wt%. A large displacement (9.3 mu C/cm(2) under 580 kV/mm) is observed so as to obtain a high discharged energy density (U-d approximate to 17.6 J/cm(3)) of the BT@BN/PVDF composites, which is 2.8 times of the PVDF film. The enhancement ratio of E-b achieved in this study demonstrates the highest among the reported results. This hybrid structure of fillers provides an effective way to adjust and improve the energy storage properties of the polymer-based dielectrics.
