AbstractThe development of active systems to protect metal substrates against corrosion is a promising approach for many industrial applications. In this work, a self-healing coating based on TiO2 particles modified with polyaniline (PANI) was prepared for corrosion protection of Q235 steel. TiO2/PANI particles were synthesized by in situ polymerization and dispersed into awater-based epoxy coating. The structure and morphology of as-prepared TiO2/PANI particles were characterized by FTIR, XRD, and SEM. The anticorrosion performance of the coating was studied by electrochemical impedance spectroscopy (EIS) and scanning electrochemical microscopy (SECM). EIS analysis showed improved corrosion protection properties in the presence of TiO2/PNAI particles. SECM measurements were performed to monitor the reduction of oxygen process as a function of exposure time in 3.5% NaCl solution. SECM results showed that the epoxy coating with TiO2/PANI particles had a superior corrosion protection relative to the blank coating after artificial defect exposure to the corrosive environment.
