A new series of Poly 2-[N-(5-vinyl-1H-1,2,3-triazol-3-methyl amino]benzo[d]thiazole(4) has been synthesized through reaction of 2-aminobenzimidazole with ethyl chloroacetate . The resulting ester was synthetically modified through hydrazine hydrate to acyl hydrazide which was condensed with acrylonitrile to afford the title 2-[N-(5-vinyl-1H-1,2,4-triazol-3-methyl) amino] benzo[d]thiazole(3). Finally, Using a controlled DC power supply, compound [3] electrochemical polymerization onto the S-steel (anode) electrode surface was carried out in a potentiostat. The polymer-coated and uncoated stainless steel corrosion safety test was studied in a solution of 0.2 M HCl, followed by Tafel and Potentiostatic procedures at temperature 293 K. Nano materials such as ZnO were applied to the monomer solution at different concentrations to enhance the resistance for corrosion the 316L stainless steel surface, so that tests showed that the performance values of corrosion protection for the polymer coating increase with the introduction of nano materials.[13C-NMR, 1H-NMR, and FTIR] were recorder to confirm the structure of poylmers, measurement of some of its physical properties and atomic force microscope(AFM), scanning electron microscope(SEM).
