Abstract
A bionic superhydrophobic coating with good corrosion resistance was prepared by one-step nano-silver deposition on a copper substrate. The superhydrophobic surface was covered with petal-like and coral-like micro/nano-structures. With the highest water contact angle of 169.9°, the superhydrophobic coating has good superhydrophobicity. The surface morphology, chemical composition, and wettability of the samples were characterized by scanning electron microscopy, Fourier transformed infrared, x-ray diffraction, and water contact angle measurement. The corrosion resistance tests showed a significant improvement on the superhydrophobic sample.
