Superhydrophobic Transparent Glass Thin Films
An article having a nanostructured surface and a method of making the same are described. The article can include a substrate and a nanostructured layer bonded to the substrate. The nanostructured layer can include a plurality of spaced apart nanostructured features comprising a contiguous, protrusive material and the nanostructured features can be sufficiently small that the nanostructured layer is optically transparent. A surface of the nanostructured features can be coated with a continuous hydrophobic coating. The method can include providing a substrate; depositing a film on the substrate; decomposing the film to form a decomposed film; and etching the decomposed film to form the nanostructured layer.
