Electrodeposition of cerium oxide films and composites

► CeO2 films were prepared by electrolytic deposition and electrophoretic deposition. ► Electrodeposition method has been developed for poly(2-vinylpyridine) films. ► CeO2-poly(2-vinylpyridine) films were prepared by electrochemical methods. ►The films provided corrosion protection of stainless steel.
