The novel polymer poly(5-methylenebenzotriazol-N-yl), denoted BTA-poly, was investigated for the protection of copper by electrochemical studies and weight loss measurements. The electrochemical measurements were compared to weight loss measurements and satisfactory results were obtained. Compared with benzotriazole, which is one of the best corrosion inhibitors for copper, BTA-poly achieves good protection under the same test conditions. Due to the rapid adsorption of BTA-poly onto copper, its corrosion-inhibition efficiency can be controlled by varying the concentration. The protecting effects of the polymers were studied in a sodium chloride solution using electrochemical measurements and an immersion test. The surface characteristics of the polymer-modified copper were analyzed via X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). These results show that BTA-poly can be easily adsorbed onto the copper surface via self-assembly to achieve excellent anticorrosion/antioxidation effects.
