The role of counter anions in anticorrosive properties of silica-polypyrrole composite

In summary, it is noted that the corrosion protection of organic coating is enhanced in the presence of silica/polypyrrole composites. However, the mechanisms of corrosion protection are complex and understanding these mechanisms is complicated by many factors that are likely to influence the processes occurring. In previous study, we investigated that the presence of oxalate anion can significantly enhance the corrosion protection performance of PVB coating. Therefore, this study is focus to understand and highlight the effect of different counter anions to the corrosion performance of silica/polypyrrole composites.
