<![CDATA[Poly4-(2-hydroxy benzamido)-4-oxo but-2-enoi cacid (PHOE) was prepared by the electrochemical polymerization of 4-(2-hydroxy benzamido)-4-oxobut-2-enoicacid (HOE) monomer on stainless steel (St.S) asanti -corrosion coating. Atomic Force Microscope (AFM), Fourier transform infrared techniques (FTIR) and cyclic voltammetry were used to characterize the properties and the structure of the polymer layer. The corrosion behavior of uncoated and coated St.S were estimated from Tafels plots using Potentiostatic technique in 0.2 M HCl solution as corrosive environment at temperature range( 293 – 323) K. Nanomaterials such as graphene and Nano ZnO in the different concentrations were added to monomer solution to improve the corrosion resistance of St.S surface so that the results showed that the values of corrosion protection efficiency for polymeric coating increase with adding Nanomaterials . In addition the kinetics and thermodynamics parameter were calculated for St.S corrosion before and after polymeric coating in the acidic medium, moreover, the influence of the prepared polymer on some strains of bacteria was studied.Keyword: Anti-corrosion, Electrochemical polymerization, Stainless steel, Coating, Antibacterial activity.]]>
