Abstract

   The exceptional application of nanocomposites containing polyaniline as a conductive polymer, poly (methyl methacrylate) (PMMA) as an acrylic resin and Fe3O4 nanoparticles, for corrosion protection of mild steel was reported. The synthesized nanocomposites, were characterized with different techniques. The resulting PMMA/Polyaniline/Fe3O4 nanocomposites were mixed with industrial alkyd paint to be employed as an anti-corrosion layer for mild steel in a NaCl solution. Accordingly, the potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) were applied in order to investigate the corrosion behavior of the coated mild steel. Based on the results, the nanocomposites showed outstanding anti-corrosion properties compared with other composites coating. After investigating various compositions of the nanocomposites (3, 6, 9 and 12%) in the alkyd paint, the ideal composition related to the most favorable corrosion protection was obtained for the paint mixture comprising 6% nanocomposites.
