This paper discusses the design of surface microstructures for quick drying. The structures produced in this study were arrays of micropillars with different sizes and pitches fabricated by photolithography. It was found that the sliding angle decreased with an increase in the pitch of the pillars. Hence, droplets could be removed easily. However, the evaporation time increased significantly. To achieve a balance between the evaporation time and the sliding angle, a reticular pattern consisting of pillars and flat areas was designed and tested. The evaporaiotn time became shorter than the fully arrayed surface on this pattern, while the sliding angle could not be made small. The evaporation time became shorter than the fully arrayed surface on this pattern, while the sliding angle could not be made small.
