Special wettability includes superhydrophobic, superhydrophilic, superoleophobic and superoleophilic etc. The superhydrophobic surfaces are governed by the surface chemistry and unique micro/nanostructures. Up to now, numerous methods have been reported in constructing superhydrophobic surfaces including chemical vapor deposition, chemical etching, hydrothermal, sol-gel and so on. Preparing superhydrophobic films on metal surfaces is an effective way to improve the anti-corrosion property of metal substrates. In addition, superhydrophobic films can be used to oil-water separation. In this work, a one-step electrodeposition was applied to prepare superhydrophobic surfaces on copper meshes. The morphology, wettability and chemical composition of the prepared films were characterized by SEM, optical contact angle meter, EDS, FTIR and XPS. The results showed that the surface on copper meshes obtained at 30 V with 10 min was uniformly covered by microcells aggregated by nanosheets. The surfaces of the copper meshes were composed of copper myristate (Cu[CH₃(CH₂)₁₂COO]₂) and reach the maximum contact angle of 156.2° with the rolling angle as low as 1°. The potentiodynamic polarization curves were utilized to analyze the corrosion resistance, which demonstrated that corrosion current densities of the superhydrophobic film was 4.77×10^-9 A/cm², decreased by more than 3 orders of magnitude, and the corrosion potential was 0.036 V more positive compared with the copper substrate. Moreover,the oil-water separation tests showed that the separation efficiency of the film after reused for 5 times maintained above 95%, exhibiting excellent oil-water property and recycle capability.
