Corrosion protection of epoxy coatings contained with phytic acid-doped polyaniline (PANI-PA) for Q235 carbon steel was studied in this work. Synthesized PANI-PA particles were characterized by XPS, TGA, and FTIR, respectively. The coating performance was investigated by OCP, EIS, and SVET, respectively. The experimental results show that the concentration of PANI-PA has a significant influence to...
The synergistic effect of tannic acid and I− in H2SO4 solution has been studied through electrochemical impedance spectroscopy, potentiodynamic polarization curves, immersion tests, weight loss tests, and scanning electron microscopy in present work. The results show that tannic acid and iodide ions have an obvious synergistic inhibiting effect in H2SO4 solution. SEM images indicate that the absorbed...
