摘要：
Electrochemical synthesis of polyaniline (PANI) on aluminum electrode from aqueous Solution Of 0.25 mol dm(-3) aniline and 0.2 mol dm(-3) sodium benzoate has been investigated under potentiodynamic and galvanostatic conditions. Initial corrosion behavior of aluminum and PANI coated aluminum electrode exposed to 3% NaCl has been investigated using electrochemical potentiodynamic and impedance spectroscopy technique (EIS). It was shown that PANI coating initially provide corrosion protection of aluminum, decreasing the corrosion current density at least 15 times. (C) 2009 Elsevier B.V. All rights reserved.
