Characterization and Study of Corrosion Behavior of Zinc Oxide Nanocomposite Coatings/Aniline Derivatives Prepared by Electrophoresis on the Surface of 304 Stainless Steel

In this research, nanocomposite coatings based on zinc oxide and homopolymers of aniline, anisidine, toluidine and aminophenol were prepared by electrophoresis on the surface of 304 stainless steel and their corrosion resistance was studied while characterizing the coatings. Polymerization took place in an acidic medium using ammonium persulfate as the oxidizing agent. The nanocomposites were characterized using FTIR, XRD and SEM techniques. The corrosion behavior of the coating in 3.5 wt% sodium chloride solution was evaluated by dynamic dynamic methods at ambient temperature. The results showed that the conductive nanocomposite as a coating reduces the rate and intensity of corrosion flow. The anti-corrosion effect of each polymer depends on the extraction group on the benzene ring and with increasing the lethality of each extraction group, the anti-corrosion effect of the polymer decreases.
