Design of Quick-Dry surface with the Help of Structured-Surface

抄録

This study aims to discuss the design of surface micro-structure for quick-drying. The prepared structures were the array of micro-pillars with different sizes and pitches fabricated by photolithography. It was found that the wider pitch of micro-pillars makes the sliding angle smaller, which means that droplets are easily removed. However, the evaporation time became longer. Thus, reticular pattern, which consists of micro-pillars and flat area, was designed and tested to obtain both of the merits. The evaporation time became shorter than the fully arrayed surface on this pattern, though the sliding angle was not improved.
