The method of double cathodic-anodic potential (current) pulses for synthesis of composite coatings Prussian blue–polypyrrole on optically transparent electrodes

Abstract

An original method of one-step electrochemical deposition of electroactive composite films from a mixed solution of precursors of the organic and inorganic components in the mode of double cathodic–anodic pulses is used for the formation of Prussian blue/polypyrrole films on the surface of optically transparent electrodes. The deposition parameters are chosen (the order of deposition of components, the number and amplitude of polarizing pulses, the pulse length) which allow the deposition of composite films with good adhesion to the electrode surface and the high stability of the redox-transition Prussian blue/Prussian white.
