Abstract
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, ϕc, and an exponent, t. A preliminary model, also based on the GEM equation, is used to describe the temperature variation of the resistivity of the diphasic material near the critical volume fraction.
