Abstract
In this work, the synergistic effect of polyaniline (PANI) and Ce cations was utilized to develop a graphene oxide (GO) electrophoretic deposition (EPD) green epoxy (EP) coating with a physical barrier and corrosion inhibition. PANI and Ce cation not only form a protective layer with inhibition but also convert the negative charge of GO to a positive charge, thus satisfying the conditions of cathodic electrophoretic deposition (C-EPD). Anti-corrosion test results showed that the GO/PANI/Ce(NO3)3 (GPC)/EP composite coating has the highest impedance, with the impedance modulus at day 35 three orders of magnitude higher than that of the neat EP coating. The passivation film generated by the GPC inhibits large corrosion extensions; it produces a significant self-healing effect, as evidenced by the corrosion morphology, the XPS analysis, and the stable value of the impedance modulus. This work provides a new strategy for manufacturing high-performance electrophoretic epoxy coatings with self-healing properties.
