摘要

采用恒电位电沉积镍,再用肉豆酱酸(MA)处理,成功地将超疏水薄膜接枝到钢基体上。利用扫描电子显微镜(SEM)对制备的超疏水膜的表面形貌进行了研究。结果表明,用肉豆酱酸修饰制备的Ni薄膜具有微纳结构。红外光谱(FTIR)和x射线衍射(XRD)测试表明,钢基体上包覆了一层肉豆酱酸改性的镍膜。制备了三种不同的镍膜;纯硫酸浴(1.0 M NiSO4)沉积的Ni-MA (I),纯氯化镍浴(1.0 M NiCl2)沉积的Ni-MA (II)。6H2O)和第三层Ni-MA (III)薄膜(0.2M NiCl2)。6H2O和0.8M NiSO4)。超疏水Ni-MA (I)膜具有最高的耐腐蚀性、化学稳定性和机械耐磨性,而Ni-MA (II)膜具有最低的性能。

Fabrication of Robust Superhydrophobic Nickel Films on Steel Surface with High Corrosion Resistance, Mechanical and Chemical Stability
Superhydrophobic films were successfully grafted on a steel substrate using potentiostatic electrodeposition of nickel followed by treatment with myristic acid (MA). A scanning electron microscope (SEM) was used to investigate the surface topography of the prepared superhydrophobic films. The results revealed that the prepared Ni films modified by myristic acid have micro-nano structures. FTIR and XRD measurements showed that the steel substrate was coated with nickel film modified with myristic acid. Three different nickel films were prepared; the Ni-MA (I) deposited from pure sulfate bath (1.0 M NiSO4), Ni-MA (II) deposited from pure nickel chloride bath (1.0 M NiCl2. 6H2O), and the third Ni-MA (III) film deposited from Watts bath (0.2M NiCl2. 6H2O and 0.8M NiSO4). The superhydrophobic Ni-MA (I) film has the highest corrosion resistance, chemical stability, and mechanical abrasion resistance, while Ni-MA (II) film has the lowest properties.
