Multiple Liquid Manipulations on Patterned Surfaces with Tunable Adhesive Property

Abstract Micro/nanostructured surfaces with designable wettability show great promise in many fields. This paper reports a new strategy for fabricating superhydrophobic surfaces with tunable water adhesion force by combining multiscale surface structures and mussel‐inspired surface chemistry, which can be used for multiple liquid manipulations. Highly ordered porous films prepared by the breath figure method enable convenient construction of surfaces with honeycomb‐patterned or nanosized pincushion‐like structures. Multiple liquid manipulations including no‐loss transportation of water droplets, water collection, programmable movement of water droplets, and chemical reaction monitoring are demonstrated on the micro/nanostructured surfaces. The proposed method is facile, energy‐efficient, and can be conducted for the preparation of superhydrophobic surfaces with high contrast adhesion patterns.
