摘　　要：Recently,ZnO-based composites have been widely applied in the field of electric power.To meet the diverse application requirements,it is necessary to figure out the I-V characteristics of ZnO composites whose high-voltage and ground-voltage electrodes are arranged on the opposite sides with a certain horizontal distance.30 vol%,40 vol%and 50 vol%ZnO-based silicone rubber composites were prepared.The horizontal distance between their electrodes was set as 50,100,500μm,1 and 2 mm,respectively.Results showed that with the increase of ZnO fillers volume fraction under a fixed horizontal distance of 100μm,from 30 vol%to 50 vol%,the I-V curves shifted left,the leakage current increased and the switching voltage decreased.When the horizontal distance between electrodes increased from 50μm to 1 mm under a fixed doping concentration of 40%,the I-V curves shifted to the right,the leakage current dropped and the switching voltage rose.The mathematical and physical models were established to explain the results.This work provides a referential significance for the practical application of ZnO composites,such as 5G folding mobile phones and power electronic modules.
