Corrosion protection of iron by polypyrrole modified by copper using the cementation process

Polypyrrole (PPy) coatings have been deposited on iron from aqueous oxalic acid solution at different current densities. The polymer deposit obtained at a current density of 2 mA cm −2 yields strongly adherent and smooth PPy layers. The modification of the film by incorporation of copper micropartic...
