摘要：

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 degrees C for 12h, 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 degrees C and a low contact angle hysteresis is achieved. The superhydrophobic surface shows strong mechanical stability and can effectively protect the copper substrate. Copyright (c) 2016 John Wiley & Sons, Ltd.
