The superhydrophobic surface on copper is fabricated by using a simple hydrothermal reaction and subsequent perfluorosilane treatment. The micro‐structured and nano‐structured surface was directly obtained through the hydrothermal reaction of copper sheets with sulfur at 180 °C for 12 h, resulting in the formation of copper sulfide film on the copper substrate. The chemical composition of this film was confirmed using X‐ray photoelectron spectroscopy. After copper sulfide film is treated by perfluorosilane, the superhydrophobic surface with static water contact angle of 153 °C and a low contact angle hysteresis is achieved. The superhydrophobic surface shows strong mechanical stability and can effectively protect the copper substrate. Copyright © 2016 John Wiley & Sons, Ltd.
