Synthesis and Investigation of Corrosion Properties of Polyortho-Aminophenol / Fe3O4 Nanocomposites Chemically Prepared on Stainless Steel 304

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.
