Abstract

Nonlinear phenomena of conductivity of composite materials are widely used in practice. However, publications concerning materials composed of a conductive phase such as conductive carbon black and another component as an insulating matrix usually consider the influence of mixture parameters on the electrical conductivity while paying less attention to nonlinear effects especially in the region of the percolation threshold. The present investigation focuses on voltage and time dependence of complex conductivity while paying less attention to other parameters even such as temperature
