Experimental study has been performed on evaporation of water droplet on a TiO_2-coated copper surface. The surface exhibits extremely high affinity for water by exposing the surface to ultraviolet ray and the contact angle decreases nearly to zero. Using this nature, we can change contact angle only without changing other thermal properties. The evaporation time was measured for single water droplet of four different diameters. Especially, the effect of contact angle on wetting limit temperature has been examined. It is found that wetting limit temperature increases as the contact angle decreases.
