Anticorrosive Properties of Oligoaniline Containing Photocured Coatings

Electro-active maleic acid capped trianiline (MTA) was synthesized by reaction of maleic anhydride with trianiline (TA). Photopolymerization of aromatic acrylate (PAA) and MTA were applied on Q235 carbon steel to afford oligoaniline containing electroactive coatings. The anticorrosion behavior of photo-cured coatings with 1 wt% and 2.5 wt% MAT was investigated in 3.5% NaCl solution via potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS). It was observed that acrylate containing MTA coatings exhibited better corrosion resistance than the pure aromatic acrylate coating did.
