Abstract
The ZnO ceramic-epoxy composite material is an excellent candidate for field grading material. The influence of ZnO filler size on the electrical properties of the ceramic-epoxy composite material was studied in this work. ZnO filler with different sizes was prepared and dispersed uniformly in the epoxy matrix. The curves of leakage current density versus electric field were measured and showed remarkable nonlinearity. With increasing filler size, the switching electric field and the resistivity both decreased significantly, while the nonlinear coefficient increased slightly. The observed results are explained physically.
