Hydrophily
The word “hydrophilic” has Greek origins and means "water love". A water drop spreads flat on a hydrophilic surface, whereas water drops roll off a hydrophobic surface. A surface is called super-hydrophilic if a water drop dissolves on the surface. A hydrophilic surface enhances the self-cleaning when it is moistened by rain.
Photo catalytic titanium dioxide coating becomes super-hydrophilic if irradiated by light. Such a surface has decisive advantages: The coating acts by its hydrophilic property like a detergent; each rain washes the dirt off the surface. The surface obtains a self-cleaning effect.
Water spreads as a thin film on the surface. No disruptive drops are visible on a window pane during the rain. The view through a coated window pane is better than through an uncoated window pane. The thin film of water on the surface supports the evaporation if it is hot. This enhances the cooling of the building, saves energy and protects the environment.
