Abstract
Hybrid material polypyrrole/PW12O403- was electrosynthesised on carbon steel electrodes in acetonitrile medium. Passivation pretreatment of carbon steel in acetonitrile/perchlorate medium was used to avoid electrodissolution of electrode during the polymerisation. These hybrid coatings were evaluated against corrosion in chloride-containing 0.05 M NaOH and solutions obtained by filtering Portland cement slurries. Cyclic voltammetry, polarisation resistance (Rp), and Fe2+ concentrations measurements showed that the obtained coatings provide good protection against corrosion in chloride-containing media.
