Electrochemical synthesis and corrosion behavior of polyaniline-benzoate coating on copper (original) (raw)

Synthetic Metals, 2011

Abstract

Electrochemical polymerization of polyaniline (PANI) coating on copper electrode was performed galvanostatically in the current density range between 0.50 and 1.25mAcm−2, from aqueous solution of 0.3moldm−3 sodium benzoate and 0.2moldm−3 aniline. The corrosion behavior of PANI coated copper and copper electrode exposed to 0.5moldm−3 sodium chloride solution was investigated by potentiodynamic and electrochemical impedance spectroscopy techniques. It was observed that
