In this article, nickel (Ni) coating was constructed on brass substrate by a simple electrodeposition technique, and myristic acid/TiO₂ composite (MTC) modifier was used to modify Ni coating. The chemical composition and surface morphology of MTC confirm that myristic acid (MA) was successfully grafted on TiO₂ nanoparticles. As a comparison, the structures of the Ni coatings were modified by MTC or MA. We found that both modified Ni coatings exhibit strong durability, self-cleaning and superhydrophobicity ability and have good prospect of decontamination. After Ni coating had been modified by MTC, the water contact angle and sliding angle of MTC-Ni were > 170° and < 5°, respectively. In addition, the MTC-Ni coating shows improved corrosion resistance, which can effectively retard the corrosion of brass. This novel and facile electrodeposition-modification route is believed to be widely applied to preparing superhydrophobic surfaces on metallic materials.

本文采用简单的电沉积技术在黄铜基材上构建镍(Ni)涂层，并使用肉豆蔻酸/​​TiO ₂复合(MTC)改性剂对Ni涂层进行改性。MTC 的化学成分和表面形貌证实肉豆蔻酸 (MA) 成功接枝在 TiO _{2 上}纳米粒子。作为比较，Ni 涂层的结构被 MTC 或 MA 改性。我们发现两种改性镍涂层都表现出很强的耐久性、自洁性和超疏水性，具有良好的去污前景。MTC改性Ni涂层后，MTC-Ni的水接触角和滑动角分别>170°和<5°。此外，MTC-Ni涂层表现出更高的耐腐蚀性能，可有效延缓黄铜的腐蚀。这种新颖且简便的电沉积改性路线被认为广泛应用于在金属材料上制备超疏水表面。
