Abstract

In this paper, traditional approaches for calculation of volume conductivity of filled-type polymer composite are summarized and, considering the important effect of interfaces, analysis for evaluating composite conductivity based on interfacial space charge accumulation theory is described. It is found that composite conductivity increases with filling concentration. The conclusion is consistent with measurement results obtained on silica filled EPR samples
