Abstract
Fourier transform infrared reflection-absorption spectroscopy (FTIRRAS) is applied to the study of corrosion protection of copper by an organic coating. Poly-N-vinylimidazole (PVI(1)) and poly-4(5)-vinylimidazole (PVI(4)) are demonstrated to be effective new polymeric anticorrosion agents for copper at elevated temperatures. Oxidation of copper is suppressed even at 400° C. PVI(1) and PVI(4) are more effective anti-oxidants than the most commonly used corrosion inhibitors, benzotriazole and undecylimidazole, at elevated temperatures. These new polymeric agents are water soluble and easy to treat the metal surface with.
