Bilayer and monolayer coatings offer good
protection against metal and alloy corrosion. The protection of copper against
corrosion via the use of metallic and polymeric coatings has been the subject
of considerable research in the last decade. In this study, ZnNi plating was successfully deposited on the Cu electrode applying current
of 7 mA with chronopotentiometry technique in the acidic solution. The PPy film
was synthesized on thin ZnNi plating which deposited electrochemically on the
copper surface. Homopolymer film was achieved using cyclic voltammetry
technique in sodium oxalate solution containing pyrrole monomer. PPy coating
provided a significant barrier property due to its lower permeability as well
as the improvement the barrier behavior in time.
