In this paper, a novel route has been developed to create a corrosion-resistant superhydrophobic surface. Regular micro-scaled rough surface was first fabricated by turning operation on the copper substrates and then stearic acid was used to reduce the low-surface energy. The obtained surface possesses excellent superhydrophobicity with a contact angle higher than 150 degrees. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and contact angle measurement were employed to characterize the surface. The formation mechanism was discussed. Tests also proved that the superhydrophobic surface demonstrated good corrosion resistance and stability. This simple, low-cost and environment-friendly method will broaden the research of superhydrophobic surfaces and be advantageous in their industrial applications.
