摘要:

以镍为基底, 采用水热法在其表面制得碱式碳酸钴纳米线薄膜, 用十二烷基硫醇进行表面修饰后其表现出超疏水性, 水滴在其表面的接触角达到152.3°, 滚动角接近5°. 研究结果表明, 薄膜表面微纳米阶层结构及低表面物质的协同作用使其呈超疏水性. 与普通镍片和硫醇修饰前的碱式碳酸钴纳米线薄膜相比, 超疏水碱式碳酸钴纳米线薄膜具有更好的抗腐蚀性. 相关研究有望为超疏水金属表面的制备及其抗腐蚀性研究提供思路.

Abstract:

Superhydrophobic film of Co(OH)2CO3 nanowires was fabricated on nickel foils by hydrothermal method. The film exhibits superhydrophobicity after being modified by dodecanthiol(DDT), water contact angle and water gliding angle on the surface is 152.3° and 5°, respectively. The results reveal that the synergistic effects of hierarchical structures with micro/nanometer scale combining with low surface energy material induced the formation of superhydrophobicity. Compared with pristine nickel foil and unmodified Co(OH)2CO3 nanowires film, the film modified with DDT performs preferable properties of anticorrosion. The researches are expected to provide a reference for the fabrication of superhydrophobic metal surface and investigations of its properties of anticorrosion.
