The Patterned superhydrophobic surfaces with controlled surface adhesion are characterized by lotus and petal effects with manipulated droplet flow. In this study, we propose a method based on liquid crystal/polymer phase separation and localized photopolymerization to realize superhydrophobic surfaces with regional adhesion variations. Two patterned surfaces with different adhesions are fabricated from superhydrophobic materials and can be used as droplet deflectors and collectors. Due to their simplicity and high functionality, superhydrophobic surfaces have great potential for practical applications in surface droplet control.
