Abstract: A durable optical film or element includes a polymerized structure having a microstructured surface and a plurality of surface modified colloidal nanoparticles of silica, zirconia, or mixtures thereof. Display devices including the durable microstructured film are also described.

Abstract: A roofing shingle may include a substrate, granules and multilayer infrared light reflecting film particles. In some cases, a roofing shingle may include a substrate, granules and a multilayer infrared light reflecting film disposed either above or below the granules. Such roofing shingles may exhibit improved solar reflectivity. An infrared light reflecting mixture may include inorganic granules and polymeric multilayer infrared light reflecting film particles. An existing construction surface may be treated to improve its solar reflectivity.

Abstract: A durable optical film includes a polymerized optical film structure having a microstructured surface and a scratch contrast ratio value in a range of 1.0 to 1.65 or 1.0 to 1. 15. These durable optical films can include a plurality of nanoparticles and a rounded prism apexes microstructure.

Abstract: Disclosed are various fluoropolymer blend combinations and multilayer articles comprising a blend in a first layer and a second layer comprising a polymer bonded to the first layer. The invention also provides an article comprising a first layer comprising a blend of two or more fluoropolymers, and a second layer bonded to the first layer, the second layer comprising a partially-fluorinated thermoplastic polymer, a perfluorinated thermoplastic polymer, or a combination thereof. The invention also provides an article comprising a first layer comprising a blend of two or more fluoropolymers, at least one of which comprises a partially-fluorinated thermoplastic polymer, and optionally at least one perhalogenated polymer, and a second layer bonded to the first layer, the second layer comprising an at least partially-fluorinated thermoplastic polymer. The invention also provides processes for preparing blended fluoropolymers and multilayer articles comprising a fluoropolymer layer.
