METAL-POLYMER CAPACITOR COMPRISING A DIELECTRIC FILM WITH HIGH DIELECTRIC CONSTANT AND STRONG BREAKDOWN FIELD

摘要

Metal-polymer capacitor comprising a dielectric film disposed between a first electrode and a second electrode, characterised in that the dielectric film comprises:core/shell structure nanoparticles, the core of the nanoparticles being metallic and the shell comprising a first layer made of an inorganic carbonaceous material and a second layer made of a first polymer material, the nanoparticles having a narrow size distribution,a matrix wherein the nanoparticles are dispersed, the matrix being a mineral matrix or a matrix made of a second polymer material.
