N2 - The ongoing demand of electrical and electronic device miniaturization puts a great challenge on energy storage materials. Development of energy storage capacitors mainly rely on development of advanced dielectric materials, which asking for high energy density and low loss. Therefore, in this work, the permittivity of poly (vinylidene fluoride) (PVDF) is carefully enhanced by doping inorganic fillers to achieve a superior energy storage performance. To avoid the degradation on breakdown strength companied with inorganic doping, titanium dioxide (TiO) nanoparticles with close permittivity and polymethyl methacrylate (PMMA) were carefully loaded. The nanocomposite presents an energy density about 5.8J/cm3 with a breakdown strength about 367kV/mm, which are about three times of polypropylene. Our results might help understand the relationship of microstructure and electric properties, and therefore provide a promising approach to develop high energy density dielectric nanocomposite.
