Abstract
A review was provided of the research progress of the inhibition mechanism of benzotriazole (BTA) as corrosion inhibitor for copper. The surface structure and composition as well as the corrosion inhibition type of protective films of BTA formed in acidic medium, nearly neutral medium and alkaline medium were highlighted. It was pointed out that BTA functioned to prevent Cu from corrosion by forming protective films on Cu surface. The formation of BTA protective films was affected by oxygen, anodic polarization, BTA concentration and pH value, while elevating BTA concentration and pH value favored the formation of the BTA protective films.
