Nonlinear field dependent conductivity dielectrics made of graphite nanoplatelets filled composites

Downsizing electronic and electric equipment requires the optimization of field distributions in order to avoid localized dielectric breakdown (also called partial discharges). This paper presents a novel composite material aimed at grading electrical local surface stress. functional has conductivity which increases by several orders with applied giving ability distribute itself. It is prepared for first time dispersing graphite nanoplatelets polymer may be used as resistive or capacitive applications. Mechanisms origin nonlinear behavior are discussed.
