The best modified electrodes, which were taken from the optimum conditions of redox behaviors, were also electropolymerized in 0.5M oxalic acid/acetonitrile (CH3CN) solution on Al1050 electrode. The modified Al1050 electrodes were characterized by optical microscope, FTIR-ATR, SEM-EDX, and EIS. The optimum conditions of the electrocoated P(3OT)/Al1050 and P(3OT)/TiO2 nanocomposites on Al1050 electrode were investigated for corrosion performances against 3.5% NaCl solution. The corrosion tests were performed by EIS and Tafel extrapolation plots together with the equivalent circuit model of R-s(Q(c)(R-c(Q(p)R(ct)))). P(3OT)/TiO2 nanocomposite films showed higher protection efficiency (PE = 89%) than P(3OT) films (PE = 81%). The P(3OT)/TiO2 nanocomposite films coated on Al1050 electrodes may be used in industrial applications of corrosion protection against salt water.en10.1080/03602559.2014.919652info:eu-repo/semantics/closedAccessCoatingCorrosionElectropolymerizationNanocompositePoly(3-octylthiophene)TiO2Electrochemical Impedance SpectroscopyThin-FilmsMechanical-PropertiesCarbon-FiberMild-SteelTio2PolyanilineAluminumElectrolytePerformanceArticle531717681777N/AWOS:0003504102000022-s2.0-84910596277N/A
