NANOSTRUCTURED ARTICLE

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. 本发明提供了一种纳米结构化制品，该纳米结构化制品包括：基底；多个第一纳米结构，该多个第一纳米结构设置在该基底上并远离该基底延伸；以及共价交联的氟化聚合物层，该共价交联的氟化聚合物层设置在该多个第一纳米结构上。该多个第一纳米结构包含聚氨酯。该聚合物层至少部分地填充该第一纳米结构之间的间隙至高于该基底至少30nm的平均最小高度，使得该聚合物层具有由该多个第一纳米结构限定并背向该多个第一纳米结构的纳米结构化表面。
