Poly (N-salicyly tetrahydrophthalamic acid) (PSP) synthesized from corresponding monomer N-salicyly tetrahydrophthalamic acid (NSP) in aqueous solution by using electrochemical polymerization process at room temperture. The polymeric film formed on stainless steel (316) surface (working electrode) and its structure examined by Fourier Transmission Infrared Region (FTIR). The anticorrosion action of the polymeric film on stainless steel (S.S316) was studied by using electrochemical polarization method in 0.2M HCl solution and temperature range (293-323)K. Kinetic and thermodynamic of activation parameters for corrosion process of S.S were calculated. The biological activity of polymeric film determined toward gram positive bacteria which is Staphylococcus aureus (Staph.Aure) and negative bacteria which is Escherichia coli (E.Coli). The effect of nanomaterials was studied by adding to the monomer solution in different concentrations to increase the efficiency of polymeric film as anticorrosion and antibacterial. The nanomaterials used in this study which are Graphene (G) and Zinc Oxide (nano) (ZnO n ).
