摘要

A new model of the CuBTA chemisorbed structure is presented. The Cu-BTA polymer is formed by strong charge-transfer interactions between benzotriazole molecules instead of by BTA-Cu-BTA connections. It successfully interprets the experimental results from solubility and tarnish resistance tests on adsorbed films on copper surfaces. It also gives a reasonable explanation for the different inhibition coefficients among BTA-treated copper single crystal surfaces. This study leads to an understanding of the benzotriazole inhibition mechanism: (1) All the copper atoms can be bound to BTA nitrogen atoms and the absence of active surface sites prevents attack by corrosive ions. (2) The BTA molecule stands vertically, or nearly so, to the copper surface, but still allows the formation of a compact protective surface film. (3) The strong infinite polymer chains stabilize the protective film and strengthen its inhibition capability. 92 refs., 26 figs., 10 tabs. (ERA citation 11:016833)
