Superhydrophilic and superhydrophobic surfaces exhibit numerous industrial applications such as self-cleaning, antifogging, anti-icing, electrowetting, and photocatalysis. A surface with reversible wetting behaviors that can be controlled by external field is both scientifically and technologically of importance. Light is a major external trigger for many natural processes. We report here an intelligent remote technology based on alternative UV and near-infrared (NIR) irradiation that enables dynamical wettability tuning of ZnO wafers. Notably, NIR irradiation with a moderate power density of 500 ± 5 mW/cm2 can rapidly recover patterned ZnO from the UV-induced superhydrophilic state (<5°) to the original state (125 ± 3°) in just 2 h. We discover that the chemical environments of O 1s and Zn 2p electrons exhibit a back-and-forth shift upon UV and NIR irradiation, respectively. The NIR-promoted wettability recovery is attributed to selective actuation of vibrational overtone transitions of hydroxyl (OH) ban...
