Abstract

A three phase predictive model is presented basedon the generalized effective medium (GEM) modified equationwhich describes the DC electrical conductivity of a wide variety of binary mixtures. Six series of two-and three-dimensional composites have been investigated, at a constant temperature, taking into account the role of interphase zone existing between the macromolecular chains and the polypyrrole fillers. The fitting of experimental data using the GEM-modified model provides to estimate the volume, concentration and intrinsic conductivity of interphase zone, depending on macromolecular network chains usedin each series..
