Abstract

The polymer was used to inhibit the corrosion of copper metal in salt media in different concentrations at room temperature using potentiometric polarization measurement. The polymer was prepared by mixing (0.1M) 4-Hydroxy aniline (C₆H₇NO) with (0.25M) of ammonium persulfate as the initiator using the electro-deposition technique. The polymer's results showed that copper in (3.5%) NaCl had good corrosion resistance. The findings demonstrate that the %IE for polymer-induced copper corrosion is 89.32% at 10 ppm concentration as a result of the 4-hydroxy aniline polymer's adsorption from salt solution on the surface of copper metal. The numbers from the polarization method and the acquired standard data agree well. The coated copper by polymer lowered the current density icorr compared to uncoated alloy.
