摘要：

Results are presented of a comparison of polarization and impedance investigations of conductive composites based on ethylene-propylene-diene-monomer (EPDM). These composites are assigned as the material for the production of polymeric anodes. It has been shown that anodic properties of the composites depend, amongst others, on the type and amount of admired carbon black. Electrochemical impedance spectroscopy (EIS) has been proposed for the determination of electrical and electrochemical properties of polymeric composites. Choice of electrical equivalent circuit and analysis of obtained spectra allow the determination of the resistance of the composite and the resistance of the anodic process occurring on the surface of the polymer. EIS can be used in investigations of conductive polymeric composites developed for cathodic protection needs.
