摘要：

In this paper, silicon carbide/silicon dioxide (SiC/SiO2) filler with core/shell structure, as a filler in epoxy resin (EP), is studied. The effect of the thickness of the SiO2 shell is studied as it affects the microstructure and electrical properties of the SiC/SiO2/EP composites at various temperatures. Compared with SiC/EP composites, the SiC/SiO2/EP composites show outstanding electrical properties. The nonlinear coefficient of the 4 nm-SiC/SiO2/EP composites increases from 2.88 (5 wt% SiC/EP) to 3.79, and the breakdown field strength increases 1.23 times. With increasing temperature, the electrical conductivity increases and the threshold field strength decreases. Moreover, as the SiO2 shell thickness increases, the breakdown field strength of the composite increases, and shows a weaker temperature dependence.
