Different monomer ratios (1:1 and 1:9) wereapplied in order to determine the suitable chain composition to synthesize the copolymer in lithiumperchlorate containing acetonitrile. The structures, morphologies, electrochemical properties andcorrosion resistances of the mono and multi-layer coatings were investigated by Fourier-transform infrared spectra, scanning electron microscope, energy dispersive X-ray spectrometer,electrochemical impedance spectroscopy and anodic polarization. Furthermore the geometric struc-ture and electronic properties of indole, aniline, and indole-co-aniline (dimmer) molecules have beeninvestigated by quantum calculations. The results indicated that corrosion protection of copolymerswas increased via titanium dioxide pre-coating. The 1:1 copolymer coating showed better corrosionprevention than 1:9 coating. The correlation was determined between experimental and theoreticalparameters.eninfo:eu-repo/semantics/openAccessStainless steel;Polymer;Electrochemical impedancespectroscopy (EIS)ArticleQ2Q1WOS:0004195985000012-s2.0-85017347337
