Abstract :
Chemically prepared Polyaniline coatings on iron electrodes were tested in chloride or sulphate solutions at neutral or slightly acidic pH for which only the emeraldine base moiety exists. However, the Raman results indicate the presence of polarons and the impedance diagrams were explained by the presence of a faradaic reaction evolving on an electronically conducting porous medium.
