Making surface of base material ultra-hydrophilic - by coating surface with layer contg. photocatalytic semiconductor material, e.g. titania, and photo-exciting material

摘要

Making the surface of a base material ultra-hydrophilic comprises coating the surface with a layer contg. photocatalytic semiconductor material, e.g. titania and photo-exciting the photocatalytic material to adjust the angle of contact of the surface of the above layer with water to ca. 10[deg] or less.
