Effect of Change in ZnO Microparticle Amount on Electrical Properties of ZnO/Epoxy Composite

Abstract

ZnO microparticles show non-liner I-V properties and they are being used in epoxy resin to make ZnO/epoxy composites. The electrical properties of composite materials depend on ZnO microparticles and their amount in the composites. In this paper, we prepared several composite samples with various amounts of ZnO microparticles and measured their electrical and dielectric properties. The diameter of ZnO micropatricles were around 20∼100 µm and they were injected to epoxy resin in different amount from 35% to 43% volume fractions. The electrical properties of our samples showed a good relationship with ZnO microparticles' amount in them. However, further works are needed to understand the effect of ZnO microparticles amount in epoxy composites.
