A facile, simple and novel method for controllable fabrication of a superhydrophobic surface was developed by spontaneous deposition and subsequent annealing on a copper substrate. The surface morphologies, chemical compositions and hydrophobicity of the as-prepared surfaces were investigated using field emission scanning electron microscopy, X-ray diffractometry, X-ray photoelectron spectroscopy and contact angle measurements. The superhydrophobic surface was composed of a hierarchical structure of CuO-Cu3Pt/Cu. At the optimal conditions, the surface showed good superhydrophobicity with a water contact angle of about 170 +/- 2 degrees and a sliding angle of approximately 0 +/- 2 degrees. Additionally, the formation mechanism of the superhydrophobic surface was studied. The as-prepared superhydrophobic surface exhibited good nonsticking behavior, long-term stability, and a large buoyancy force, which offers possibilities for potential applications.
