Superhydrophobic film with cauliflower-like structure was prepared on copper sheet by one-step electrodeposition method. The surface morphology and chemical composition of the superhydrophobic film were characterized by SEM, FTIR, XPS and contact angle measurements. Due to the cauliflower-like hierarchical structure and low surface energy, the as-prepared surface can reach up to a maximum contact angle of 158.3°, and the rolling angle is not more than 7°. Polarization curve was investigated using electrochemical workstation, and the as-prepared superhydrophobic surface showed improved corrosion resistance compared with bare copper.
