Using this procedure, the surface of the electrodes was clearly covered with a black copolymer layer of strongly adherent homogeneous characteristics. In order to evaluate the corrosion performance of copolymer coated (CuZn/PANI-co-POA) and uncoated electrodes in 3.5% NaCl, AC electrochemical impedance spectroscopy, anodic polarisation plots and open circuit potential-time curves were used. The copolymer films exhibited significant protection efficiency against the attack of corrosive agents and reduced drastically the corrosion rate of the brass.eninfo:eu-repo/semantics/closedAccessBrassCopolymersElectrochemical impedance spectroscopyCorrosionConference Object441121910.1179/174327807X2346972-s2.0-65249125122Q3WOS:000265316200002Q2
