AbstractNovel quaternary ammonium cation containing tetraaniline (QATA) was successfully synthesized by condensation of amine-capped tetraaniline with 6-bromohexanoic acid, followed by quaternarization with triethylamine. The corrosion inhibition performance of QATA with their adsorption mechanisms for Q235 steel was studied in 1 M HCl solution by a series of methods such as weight loss measurements, potentiodynamic polarization, electrochemical impedance spectroscopy, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and atomic force microscopy (AFM). The inhibition efficiency (IE%) increased with increasing concentrations of QATA, reaching a value up to 97.47% at a concentration of 150 mgl(-1). Potentiodynamic polarization curves showed that the QATA affected both cathodic and anodic protection and was a mixed type inhibitor in 1 M HCl corrosive medium. Adsorption isotherm studies confirmed that the absorption of QATA on the Q235 steel surface in 1 M HCl solution obeyed Langmuir adsorption isotherm, and the adsorption process of corrosion inhibition on Q235 steel surface involved both the physical and chemical adsorption. The EDS analysis determined the adsorption of QATA molecules on the steel surface, the surface morphologies before and after immersion in 1 M HCl medium were also investigated by SEM and AFM.
