Abstract
Electrostatic capacitors with fast storage and release of electrical energy have been playing an impor-tant role in energy field industries such as shipboard inverters,naval aircraft ejection devices,and photovoltaic/wind power generation,enhancing the energy storage density(Ue)of capacitor dielectrics can significantly acceler-ate the development of this industry.Here,polyvinylidene fluoride(PVDF)was used as the matrix and barium ti-tanate(BaTiO3)ceramics were introduced to enhance the dielectric constant(εr)of the matrix.To mitigate the de-crease in breakdown strength(Eb)of the composites due to the introduction of high-εr ceramics,boron nitride nanosheets(BNNS)were intercalated with PVDF/BaTiO3 to prepare ternary composites.Experiments and simula-tions reveal that the highly insulating BNNS can achieve the simultaneous enhancement of Eb and εr of the compos-ites and obtain a Ue of 9.7 J/cm3 at 396 MV/m electric field,which provides a basis for alleviating the contradic-tion between Eb and εr and preparing high energy storage density dielectrics.关键词
