Abstract: 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.

Abstract: The disclosed aliphatic thermoplastic polyurethane composition is well suited for use in thin, flexible light directing articles to impart flexibility, toughness, or protection to the light directing articles that contain optically active elements. The disclosed aliphatic thermoplastic polyurethanes have improved thermostability at higher temperatures. Specifically, the disclosed aliphatic thermoplastic polyurethanes have a cross-over temperature greater than 110° C. In one embodiment, the cross-over temperature is greater than 130° C. In one embodiment, the cross-over temperature is less than 170° C. and a Tg greater than 35° C. and less than 70° C.

Abstract: A display film includes a transparent glass layer having a thickness of 250 micrometers or less, or in a range from 25 to 100 micrometers. A transparent energy dissipation layer is fixed to the transparent glass layer. The transparent energy dissipation layer has a glass transition temperature of 27 degrees Celsius or less and a Tan Delta peak value of 0.5 or greater, or from 1 to 2.
