Abstract. Since the discovery of conductive polymer composite in the 70s; different mixing laws developed from the effective medium theory have been proposed to describe the physical behavior of these materials. Two models based by percolation theory have been applied to predict the AC electrical conductivity of carbon black/epoxy composites. McLachlan and Mamunya models show satisfactory results considering the parameters related to these models as adjustable parameter. These adjusted parameters do not vary significantly as a function of frequency.
