Abstract (EN): The electrochemical synthesis of polypyrrole on iron has been fruitfully achieved in aqueous medium of sodium saccharinate and pyrrole. The obtained coating under these conditions has been reached with cyclic voltammetry and chronomethods. The applied current density has a great effect on the thickness of PPy electrodeposited on iron electrodes. The characterization techniques show a good homogeneity of the PPy coating. The corrosion behaviour of PPy/Fe was investigated in sodium chloride by linear polarization, electrochemical impedance spectroscopy, and weight loss. The results show that PPy coating electrodeposited could provide a good protection against corrosion.
