用表面增强拉曼散射（ＳＥＲＳ）技术研究了缓蚀剂咪唑（ＩＭ）与苯并三唑（ＢＴＡＨ）在铜电极上的共吸附行为．实验表明，ＩＭ与ＢＴＡＨ能共吸附于Ｃｕ电极表面，ＩＭ的存在有利于ＢＴＡＨ的吸附，二者有良好的协同效应．
The co-adsorption behavior of imidazole (IM) and benzotriazole (BTAH) on Cu electrode was investigated by surface enhanced Raman scattering (SERS) technique. Experiments show that IM and BTAH can be co-adsorbed on the Cu electrode surface, the presence of IM is conducive to the adsorption of BTAH, the two have a good synergistic effect.
