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.
