Abstract
Polyaniline (PANI) hollow microspheres were synthesized by self-assembly method in poly (2-acrylamido-2-methylpropane sulfonic acid) (PAMPS) aqueous solution. Ce3+ ions were doped onto PANI hollow microspheres and further blended with Zn particles to prepare polyaniline/zinc/cerium nitrate composites. PANI/Zn/Ce(NO3)3 was applied as additives and dispersed in epoxy resin by mechanical grinding. Anticorrosion properties were investigated by electrochemical impedance spectroscopy (EIS). Bode plots showed that impedance value in low frequency region maintained at 106â¯Î©Â·cm2 after 70â¯days of harsh corrosion in 3.5â¯wt% NaCl aqueous solution. EIS results revealed that PANI/Zn/Ce(NO3)3-epoxy coating has excellent anticorrosion properties.
