摘要：

A quantitative general effective media (GEM) equation is used to describe a broad range of experimental resistivity-volume fraction results for graphite-polymer and carbon black-polymer composites. The parameters used are the resistivities of each component and the two percolation morphology parameters, a critical volume fraction, phi(c) and an exponent, t. A preliminary model, also (sic) based on the GEM equation, is used to describe the temperature variation of the resistivity of the diphasic material near the critical volume fraction.
