Abstract
ABSTRACT Functional methacrylate polymer coatings can help retard materials from corrosion. However, the antibacterial-based anticorrosive coating of methacrylate polymer is very limited. In this paper, a functional methacrylate, namely, p-acetamidophenyl methacrylate was copolymerized with N-vinylpyrrolidone and it was characterized by Fourier transform infrared spectroscopy, 1H and 13C nuclear magnetic resonance spectroscopy. Thermal analyses of copolymers were studied by thermogravimetric analysis. The polymers were tested for their in vitro antibacterial activity by well diffusion method against microbes using ampicillin as a standard. The corrosion behavior of mild steel specimens coated with different ratios of copolymers has been studied by potentiodynamic polarization and electrochemical impedance spectroscopic methods. It was showed that the copolymer-coated specimens exhibited high protection efficiency than uncoated one. GRAPHICAL ABSTRACT
