【摘要】 X射线光电子能谱结果表明,希夫碱邻香兰素邻氨基酚V-bso可以在Cu及CuO表面形成自组装膜,V-bso／Cu膜中Cu是以Cu(0) 和Cu(Ⅰ)为主,而V-bso在CuO表面形成的膜中,Cu是以Cu(Ⅱ)为主。Nyquist阻抗谱表明两种膜在NaCl溶液中都有很好的缓蚀效率 (大于92％),并且铜表面的CuO膜也能起到缓蚀作用。用等效电路对交流阻抗数据进行拟合的结果显示,V-bso／CuO自组装膜的缓蚀效率要比V-bso／Cu的好,这可能是因为在V-bso／CuO自组装体系中存在内外两层膜。更多还原

【Abstract】 Schiff base can form monolayer films on the surfaces of copper and oxidized copper. They have good corrosion inhibition (more than 92%) in NaCl solution. The valences of the copper are different in both of them. The former is +1. The later is +2. The results of the fitting equivalent circuits show that the IE of the V-bso modified oxidized copper is better than that of the V-bso modified clean copper just because the former has two layers.更多还原
