Synthesis of Nanostructured Conductive Polypyrrole and Polyaniline Films for the Electrophoretic Deposition of Solid Electrolyte Coatings

Le résumé fourni par la source

Abstract Nanostructured conductive polypyrrole (PPy) and polyaniline (PANI) polymer films are synthesized on nonconductive ceramic substrates by chemical polymerization for the subsequent electrophoretic deposition of solid electrolyte coatings in the solid oxide fuel cell (SOFC) technology. The morphological features of the PPy and PANI polymer films are identified; the dependence of surface conductivity on synthesis conditions is revealed. Charge transport mechanisms in conductive PPy and PANI films synthesized on nonconductive supporting substrates are proposed. The specific features of the electrophoretic deposition of solid electrolyte coatings on nonconductive ceramic substrates with sublayers of conductive PPy and PANI polymers are described.
