Abstract
The effect of surface wettability on evaporation of a water drop has been examined experimentally using surfaces with various contact angles. To greatly change the surface wettability, TiO2 superhydrophilicity, plasma irradiation, and super-water-repellent surface are adopted as the heating surface. The range in contact angle achieved by these methods was between 0° and 170°. The relationship between the contact angle and the wetting limit temperature was obtained and it was found that the lifetime of a water drop dramatically decreases with contact angle in the lower temperature region, and that the wetting limit temperature increases with the contact angle.
