Superhydrophilic coatings

Superhydrophobic coatings have received significant publicity in recent years, particularly in regard to claims of keeping surfaces clean. However, it occurs to me that superhydrophilic coatings will have numerous potential uses as well.

A superhydrophilic coating counter-acts water's surface tension property allowing a thin film of water to be maintained on a surface. In relatively moist environments a superhydrophilic coating may help keep a surface clean by maintaining a thin film of water that prevents the adhesion of "dirt" and may provide lubrication.
