Corrosion is considered as the most common cause of steel material property degradation, while coatings are effective and popular corrosion protection methods. Coatings come in a variety of forms, each with its own set of effectiveness, methods and constituents. This study used an electrochemical oxidation approach to make Poly [N-(۴-Methoxy Phenyl) maleamic acid] from monomer [N-(۴-Methoxy Phenyl) maleamic acid] (NPM) in a ۳.۵% seawater solution. On a low carbon steel [L.C.S] electrode (working electrode), a polymer film was produced. The polymer was created, according to infrared, SEM and FTIR examinations. Using the electrochemical polarization approach, the anticorrosion function of polymer films on L.C.S was examined. Also, adding nanoparticles (NP), like CuO and ZnO to the monomer solution improved the polymers anticorrosion. The results revealed that there was an increase in the L.C.S corrosion rate with the increase of temperature from ۲۹۳K to ۳۲۳K, while the values related to coatings polymer inhibition efficiency improved with NPs addition. For the corrosion of L.C.S in salt medium prior to and following polymeric coating, thermodynamic and kinetic activation parameters were estimated. The impact of preparing polymers on certain bacteria strains was also investigated.
