Abstract
Results have been presented of potentiodynamic and impedance investigations of conducting polymeric composites based on the polyethylene matrix with addition of DuPont vinyl acetate (Elvax 450). High conducting carbon black was the main conducting component of investigated polymeric composites. Improvement of the current output of composite electrodes was realised by introduction of active ruthenium dioxide. Statistical analysis was carried out of potentiodynamic dependencies allowing determination of relations of the current output of designed electrodes in the function of the percentage of introduced oxide. An improvement of electrochemical parameters has been shown characterising polymeric composites with increase of the percentage of ruthenium oxide.
