Abstract
A metal oxide coating has a nanotextured surface defined by a plurality of capillary openings arranged in a pattern on the surface of the coating. Each of the capillary openings have a diameter defined by a previously present organic macromolecule. The metal oxide coating is formed by depositing a solution containing uniformly dispersed micelles composed of amphiphilic molecules on a metal, oxide, or plastic substrate. The micelles are self-arranging, in solution, as a result of mutually repulsive electrostatic forces on the surface of the micelles, and form a uniformly patterned organic template when the solution is deposited on the surface of the substrate. A metal oxide coating is then applied to the substrate, which forms a ceramic monolayer that is a negative image of the organic template. The organic template is then removed, thereby forming a metal oxide coating having a plurality of macromolecular-sized apertures formed therein.
