Abstract Polyaniline-SiO2 was in situ synthesized and doped by p-toluenesulfonic acid (p-TSA). The composites were characterized by FTIR, SEM and TEM. The corrosion performance of polyaniline-SiO2 pigmented waterborne coating on carbon steel was studied by electrochemical testing technique in 3.5% NaCl solution. The tested results showed that a passivation effect and a positive shift of corrosion potential occurred due to the application of coating on metals and the anticorrosion property was enhanced.
