A gas‐driven ultrafast adhesion switching of water droplets on palladium‐coated Si nanowire arrays is demonstrated. By regulating the gas‐ambient between the atmosphere and H 2 , the super‐hydrophobic adhesion is repeatedly switched between water‐repellent and water‐adhesive. The capability of modulating the super‐hydrophobic adhesion on a super‐hydrophobic surface with a non‐contact mode could be applicable to novel functional lab‐on‐a‐chip platforms.
