摘要

Poly[(pyridine-4-yl-methyl)methacrylate-co-butyl methacrylate] [poly(PyMMA-co-BMA)] and its ZnO nanocomposites [poly(PyMMA-co-BMA)/ZnO] were coated on the mild steel substrate (MS) to improve the corrosion resistance by blocking the destructive ultraviolet radiation (UV-radiation) and corrosive ions as well. The optical and anticorrosive properties of poly(PyMMA-co-BMA) and poly(PyMMA-co-BMA)/ZnO (1.0, 1.5, and 2.5 wt %) coatings were evaluated. The surface characterization techniques like UV visible spectroscopy and scanning electron microscope were taken to confirm the formation of poly(PyMMA-co-BMA) and poly(PyMMA-co-BMA)/ZnO (2.5 wt %) coating on MS. The optical studies revealed that the poly(PyMMA-co-BMA)/ZnO (2.5 wt %) coating displays excellent UV blocking properties than other nanocomposite coatings (1.0 and 1.5 wt %). The potentiodynamic polarization and electrochemical impedance spectroscopy studies show that the poly(PyMMA-co-BMA) and poly(PyMMA-co-BMA)/ZnO (1.0, 1.5, and 2.5 wt %) coated MS in 3.5% (w/v) NaCl provides better protection against corrosion.
