报道了一种通过构建三维(3D)十二硫醇自组装单分子膜(SAM)来提高铜在3.5%NaC l溶液中耐蚀性的新的、简单的方法。将几滴1%的H3PO4溶液稀薄均匀地分布在铜表面，形成由Cu3(PO4)2纳米花组成的三维纳米结构。评价了十二硫醇SAM在铜表面和经磷酸溶液处理后的铜表面的耐蚀性能。结果表明，裸铜表面的十二硫醇自组装膜具有良好的防护性能，而经磷酸溶液处理的铜表面可显著提高其耐蚀性能。
A novel and simple method to improve the corrosion resistance of copper by constructing a three-dimensional (3D) 1-dodecanethiol self-assembled monolayer (SAM) in 3.5% NaCl solution is reported in this study. Several drops of 1% H3PO4 solution are thinly and uniformly distributed on copper surface to form a 3D nanostructure constituted by Cu3(PO4)2 nanoflowers. The anticorrosion properties of 1-dodecanethiol SAM on copper surface and on copper surface that is treated with H3PO4 solution were evaluated. Results demonstrated that 1-dodecanethiol SAM on bare copper surface exhibits good protection capacity, whereas a copper surface that is pretreated with H3PO4 solution can substantially enhance the corrosion resistance of 1-dodecanethiol SAM.
