Abstract
The copolymer poly(N-(pbromophenyl)-2-methacrylamide-co-ethyl methacrylate) has been synthesized by free radical solution polymerization. Thermal stability of the synthesized copolymer was analyzed using thermogravimetric analysis and differential thermal analysis techniques. The corrosion performances of low nickel stainless steel specimens coated with different mole ratios of poly(PBPMA-co-EMA) were investigated with 1 M H2SO4 using potentiodynamic polarization, electrochemical impedance spectroscopic studies and chronoamperometric studies. Moreover, all the mole ratios of this copolymer showed good protection against corrosion. Surface and morphological investigation of the product have been studied with the help of scanning electron microscopic, atomic force microscopic, and energy dispersive X-ray analysis techniques, they were used to characterize the adherence and uniformity of the coatings, electrochemical corrosion test and surface analysis results have proved that poly(PBPMA-co-EMA) coatings served as a stable host matrix on low nickel stainless steel as environmentally more favored and best anticorrosive coating.
