In recent work related to the electrodeposition of PPy from an aqueous pyrrole-oxalic acid solution, the influence of the iron surface pretreatment on the corrosion properties was reported by Van Shaftinghen, Deslouis et al. [79]. The performances of PPy-coated iron samples, obtained through three different electropolymerization techniques were tested (i) electropolymerization at constant current (1 mA cm ) (denoted galstat), (ii) potentiostatic electropolymerization at IV vs. Ag/AgCl in oxalic acid for 600 s followed by addition of pyrrole into the solution (denoted one-step), (iii) potentiostatic polarization in a two-step process identical to the previous one, except that a prehminary polarization at 0 V vs. Ag/ AgCl for 600 s was carried out in the electrolyte alone (denoted two-step) (Figure 16.11). From the anodic curves of iron in oxalic acid alone, a first zone of potential ranging... [Pg.651]

A conductive polymer film of polypyrrole doped with polymolybdate anions was electrodeposited onto steel and found to provide corrosion protection in neutral and acidic 3.5% NaCl solution [152]. The anodic codeposition of polypyrrole and Ti02 onto mild steel in an oxalic acid medium has been described [153,154]. The PPy and Ti02 composite showed a considerable improvement in anticorrosion properties with respect to PPy films in salt spray and weight-loss tests. It was suggested that these composite films could be applied as a primary coating replacement for the phosphatized layers on mild steel [154]. [Pg.1624]
