<br/><br/> The materials used in this work are ethylene peropylene diene monomer (EPDM) and acrylonitrile butadiene rubber (NBR) five group of different blend ratio all samples follow the fickian diffusion mechanism the current - voltage characteristics of carbon blak - polymer composites are studied the free electron density and the free carrier mobility were calculated the de conductivity as a function of HAF carbon black content and blend ratio
