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.

In this study, a 10% w/w PolyorthoAminophenol/Ferric oxide nanoparticle (PoAP / Fe3O4) nanocomposite film was chemically prepared, then a polymer mixture with other polymers such as polyvinyl alcohol (PVA), polyvinyl pyrolidone (PVP), polyvinylacetate (PVAc), pure polyacrylate (PA) and polyacrylate/styrene (PAS)  was prepared in N-methylpyrrolidone solvent. The results showed that the corrosion resistance behavior of the nanocomposite depends on the added polymer matrix, so that the best protection is obtained when pure polyacrylate is used PoAP / Fe3O4 nanocomposite is characterized by the use of scanning electron microscopy (SEM), infrared spectroscopy (FT-IR) and X-ray diffraction (XRD) to determine the structure and morphology and magnetometry (VSM) to determine magnetic properties. Corrosion protection of coatings on stainless steel 304 metal in 3.5% sodium chloride solution was evaluated by electrochemical methods at ambient temperature. Corrosion test was performed with potentiostat-galvanostat apparatus with three electrodes.
