采用简单的浸渍镀膜法在未刻蚀的铜表面制备了一种辅助多巴胺优先附着的棒状1-十二硫醇薄膜。通过水接触角测量、扫描电子显微镜(SEM)和X射线光电子能谱(XPS)对薄膜的形成和表面结构进行了表征。聚多巴胺涂层的铜表面一旦形成1-十二硫醇薄膜，表面就由亲水变为疏水。通过电化学阻抗谱(EIS)对功能膜的腐蚀行为进行了评价。改性铜表面具有良好的耐蚀性能，其原因是膜结构致密，海水稳定性好，尤其是在限制氯离子的渗透方面。(C)2009爱思唯尔B.V.保留所有权利。
A rod-like 1-dodecanethiol film assisted with the preferential adhesion of polydopamine was prepared on the non-etching copper surfaces by a simple dip-coating method. The formation and surface structure of the film were characterized by water contact angle measurement, scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS). Once the 1-dodecanethiol film formed on the polydopamine-coated copper surface, the hydrophilic surface changed to hydrophobic. The corrosion behavior of the functional films was evaluated by the electrochemical impedance spectroscopy (EIS). The excellent corrosion resistance property could be ascribed to the compact film structure and good seawater stability for modified copper surface, especially in limiting the infiltration of Cl(-).
