This abstract first appeared for US patent application 18817455 titled 'NANOSTRUCTURED ARTICLE

Original Abstract Submitted

A nanostructured article includes a substrate; a plurality of first nanostructures disposed on, and extending away from, the substrate; and a covalently crosslinked fluorinated polymeric layer disposed on the plurality of first nanostructures. The plurality of first nanostructures includes polyurethane. The polymeric layer at least partially fills spaces between the first nanostructures to an average minimum height above the substrate of at least 30 nm such that the polymeric layer has a nanostructured surface defined by, and facing away from, the plurality of first nanostructures.
