Process and electrolytic bath for producing by electropolymerization a homogeneous and adherent polypyrrole coating on surfaces of oxidizable metals

摘要

The electro-polymerization for polypyrrole coating of oxidizable metal surfaces comprises electrolytic deposition from an eg. aqueous pyrrole solution, with or without stirring. Also claimed is a bath implementing the process. CLAIMED - The bath gives a homogeneous adhering coating, and the solution incorporates ions of maleate (hydro succinate) (C4O5H4)2-.
