Polyaniline/Epoxy Composite Emulsion Coatings for Anticorrosion to Mild Steel

Abstract:

Doped water-dispersible polyaniline (PANI) emulsion were synthesized by emulsion polymerization in aqueous medium and characterized by dc conductivity and Transmission electron microscope (TEM). The results showed the PANI has bar-like shape and the diameter is about 200nm. The composite anticorrosion coatings of PANI emulsion and waterborne epoxy resin emulsion (EP) were prepared by mixture in aqueous medium and used for corrosion protection of mild steel. Open circuit potential (OCP) and Electrochemical impedance spectroscopy (EIS) demonstrated that the PANI/EP composite coatings have better anticorrosion properties than EP. It’s impedance and corrosion potential is higher. Scanning electron microscope (SEM) and Energy dispersive spectrometer (EDS) showed that the oxidation film formed on the metal surface and prevent corrosion effectively. The anticorrosion coatings are environmental friendly because of water dispersion medium.
