    Abstract: A metal oxide coating (18) has a nanotextured surface (22) defined by a plurality of capillary openings (20) arranged in a pattern on the surface of the coating (18). Each of the capillary openings (20) have a diameter defined by a previously present organic macromolecule. The metal oxide coating (18) is formed by depositing a solution containing uniformly dispersed micelles (10) composed of amphiphilic molecules on a metal, oxide, or plastic substrate. The micelles (10) are self-arranging, in solution, as a result of mutually repulsive electrostatic forces on the surface of the micelles (10), and form a uniformly patterned organic template (14) when the solution is deposited on the surface of the substrate (16). A metal oxide coating is then applied to the substrate (16), which forms a ceramic monolayer that is a negative image of the organic template (14). The organic template (14) is then removed, thereby forming a metal oxide coating (18) having a plurality of macromolecular-sized apertures (20) formed therein.

    Abstract translation: 金属氧化物涂层(18)具有由以图案布置在涂层(18)的表面上的多个毛细管开口(20)限定的纳米纹理表面(22)。 每个毛细管开口(20)具有由先前存在的有机大分子限定的直径。 金属氧化物涂层(18)通过在金属,氧化物或塑料基底上沉积含有由两亲性分子组成的均匀分散的胶束(10)的溶液而形成。 由于胶束(10)的表面上相互排斥静电力的结果,胶束(10)在溶液中是自行布置的,并且当溶液沉积在胶束(10)的表面上时,形成均匀图案化的有机模板(14) 基板(16)。 然后将金属氧化物涂层施加到衬底(16),其形成作为有机模板(14)的负像的陶瓷单层。 然后去除有机模板(14),从而形成其中形成有多个大分子尺寸的孔(20)的金属氧化物涂层(18)。
