【 摘 要 】

Poly4-oxo-4-(4-sulfamoylphenylamino) but-2-enoicacid (POSPAEA) was prepared by the electrochemical polymerization of 4-oxo-4-(4-sulfamoylphenylamino) but-2-enoicacid) (OSPAEA) monomer on 316L stainless steel as anti-corrosion coating. scanning electron microscope (SEM), Atomic Force Microscope (AFM) and Fourier transform infrared techniques (FTIR) were used to identify the structure of the polymer layer. also The corrosion behavior of uncoated and coated 316L stainless steel were estimated from Tafels plots using Potentiostatic technique in 0.2 M HCl solution as corrosion medium at temperature ranging (293-323) K. Nano materials such as graphene and ZnO Nano in different concentrations were added to monomer solution to improve the corrosion resistance of 316L stainless steel surface so that the results showed that the values of corrosion protection efficiency for coating polymer increase with adding Nano materials. In addition the kinetics and thermodynamics of parameter were calculated for corrosion process 316L stainless steel before and after polymer coating in the acidic medium.
