The formation of dark brown PAHP on copper surface was characterized by cyclic voltammetry, FTIR and scanning electron microscopy techniques. The corrosion characteristics of copper/PAHP electrode were evaluated by electrochemical methods and electrochemical impedance spectroscopy in 3.5% NaCl solution. The obtained results indicated that PAHP thin film coating was an excellent inhibitor and controlled copper corrosion against corrosive agents in 3.5% NaCl solution.
