用AES、XPS、FTIR和原位（in situ)扫描隧道显微镜（STM）等方法表征研究了在含氯化钠的2-巯基苯并恶唑（MBO）溶液中铜样品表面所形成的缓蚀膜。研究结果表明，MBO是成膜型缓蚀剂，它在铜发生腐蚀的条件下，通过化学反应在铜表面形成不溶且致密的膜，从而起到缓蚀作用。其中的S和N原子在缓蚀膜构成中起重要作用。
The protection film formed on copper in 1mmol/L MBO solution containing NaCl,was characterized and studied by means of AES,XPS,FTIR and in situ STM.The FTIR characteristics for the surface of copper sample immersed in the solution for various durations were different from that for MBO.XPS data indicated that the chemical circumstance of S and N atoms in the MBO inhibition film formed in MBO + NaCl solution changed evidently in compact three-dimension film on copper surface in MBO solution containing NaCl.It is concluded that MBO reacted with the cuprous species from copper corrosion,and produced a water-insoluble material to form the inhibition film.
