Analysis of Electrical Properties in ZnO-based Epoxy Nanocomposites

Abstract

In recent times, epoxy nanocomposites have been considered as a potential indoor insulation application in power apparatuses due to significantly improved electrical and thermal properties over conventional insulators. The paper discusses the FE analysis of electrical properties of ZnO (zinc-oxide)-based epoxy nanocomposites. The results demonstrate the effect of % volume fraction and frequencies on capacitance, real permittivity, displacement current density, and conduction current density. It has shown the capacitance has changed by 21.36% with a 10% volume fraction at 1000 Hz as compared to the neat epoxy. Besides, the reasons for the advancement in real permittivity and current densities have been discussed.
