ELECTROCHEMICAL SYNTHESIS OF POLYANILINE ON VAPOR-DEPOSITED POLYANILINE LAYERS

Polyaniline is synthesized electrochemically on the surface of the lay ers deposited on transparent conducting SnO2-based electrodes by fract ional thermal vapor deposition of emeraldine base in vacuo. The synthe sis is conducted in the galvanostatic mode, in aqueous solutions of an iline hydrochloride. It is shown that, prior to the commencement of th e electrochemical process, vapor-deposited polyaniline undergoes proto nation. At the initial stages, the electrochemical process is conjugat ed with oxidation of the layer deposited. Highly homogeneous polyanili ne layers of different configurations can be obtained on conducting su bstrates by this method.
