    摘要： A method for providing a superhydrophobic surface on a structure, for example aircraft wings, propellers and/or rotors, is set forth. The method includes applying a coating of hydrofluoric acid over a titanium substrate. A voltage is then applied across the titanium substrate so that current flows through the titanium substrate. The current flowing through the titanium substrate causes the hydrofluoric acid to react with the titanium substrate to anodize the titanium substrate. The anodization causes a nanoporous titanium oxide layer to grow across the titanium substrate. The titanium oxide layer includes a plurality of nano-tube structures that, once the remaining hydrofluoric acid is washed away, provide a microscopically rough surface on the titanium substrate. A conformal coating of a hydrophobic compound is then desposited on the microscopically rough surface to create a superhydrophobic surface. Thus, a substantially self-cleaning superhydrophobic surface is created on the titanium substrate, whereby, when exposed to ultraviolet light, the titanium oxide layer has a photocatalytic reaction with oxygen to oxidize any organic contaminants that may gather on the superhydrophobic surface.

    摘要： A layered construction for application to a device or substrate or placement in an enclosed space for use in decontaminating the underlying surface or enclosed space comprises a cathode, an electrolyte layer, an anode and a protective surface layer. A compound that can be electrically decomposed to release on demand and over an extended period of time, an oxidant is included in the layered structure, preferably in the electrolyte layer. Preferred compounds are those which can release halogen ions which react with various different chemical or biological contaminants which may contact the protective layer, destroying, or devitalizing the contaminants.

    摘要： Size reduction of surface features is accomplished by stretching an elastomeric sheet isotropically, coating it with a curable elastomer precursor, impressing a surface pattern into the precursor coating with a mold, curing the precursor coating to form a patterned elastomeric coating on the substrate elastomeric sheet, removing the pattern mold, and then allowing the substrate elastomeric sheet to relax to its original size. The cured patterned coating is forced to contract isotropically by the relaxing elastomeric sheet, creating a new surface pattern whose features will be reduced in size, while retaining the relief of the features.

    摘要： A method of forming a superhydrophobic material (66) includes mixing a hydrophobic material (24) with soluble particles (26) to form a mixture (32). The mixture (32) is cured. A portion of the soluble particles (26) is etched away from the mixture (32) to form the superhydrophobic material (66). A superhydrophobic material forming system (10) includes a mixer (30) that mixes a hydrophobic binder (24) with soluble particles (26) to form the mixture (32). A curing station (16) cures the mixture (32). An applicator (69) applies a solvent (68) to the mixture (32) to etch away a portion of the soluble particles (26) from the mixture (32) to form the superhydrophobic material (66).
