摘要：

Coating strategies for corrosion protection considering intrinsically electronic conducting polymers have become important mainly because of restrictions on the use of heavy metals due to their environmental problems. This work presents the electrochemical behavior of an acrylic blend formed by sulfonate-doped polyaniline and poly(methyl methacrylate) used for corrosion protection of iron in chloride solutions. The results would indicate that these blends have a dual protection mechanism; forming a passivating complex with the dopant anion (camphorsulfonate) and simultaneously acting as a physical barrier to avoid chloride anion penetration.
