This study disscusses the microstructure design on the surface to remove any liquid effectively. Firstly, an evaluation method was proposed to discuss the removal rate of the liquid rather than traditional measurement of contact angle and sliding angle. Secondly, the effect of groove specifications on the residual area of liquid was discussed. To remove water, fine structure was preferable and its orientation was not so important. On the other hand, in the case of oil, the perpendicular groove to the flow direction was effective. Moreover, it was found that the V-shaped array groove might strengthen the effect utilizing both of the capillary force and anisotropy of wetting.
