Abstract

The effects of nano-particles on the electrical properties of the epoxy/ZnO nano-composites are studied and the nonlinear conduction characteristics of the nano-composites are discussed. The morphology structure, relative permittivity, DC breakdown strength and DC conductivity of the nano-composites are measured. Micro-structure analysis shows that the ZnO nano-particles were well dispersed in the epoxy matrix. Experimental results show that the relative permittivity and DC conductivity of epoxy nano-composite with the filler loading of 0.5 wt% are lower than those of pure epoxy and the other nano-composites, but the 0.5 wt% has the highest breakdown strength among the epoxy/ZnO nano-composites. In addition, when the filler loading is larger than 0.5 wt%, the epoxy/ZnO nano-composite exhibits a distinct nonlinear conduction character, namely, that the DC conductivity is greatly dependent on the applied electric field. The variation of the electrical properties and the nonlinear conduction character against the filler loading may be attributed to the interaction zone around the nano-particles.
