Abstract:
A process for preparing surfactant-polycrystalline inorganic nanostructured materials having designed microscopic patterns, comprising:a) forming a polycrystalline inorganic substrate having a surface;b) placing in contact with the surface of the substrate, a surface having a predetermined microscopic pattern;c) placing in contact with the surface having the predetermined microscopic pattern, an acidified aqueous reacting solution, wherein the reacting solution comprises an effective amount of a silica source and an effective amiount of a surfactant to produce a mesoscopic silica film upon contact of the reacting solution with the surface of the polycrystalline inorganic substrate;d) applying an electric field to the surface of the microscopic pattern, the electric field being sufficient to cause enhanced rates of fossilization.
