Fluoropolymeric multilayer optical film and methods of making and using the same

Abstract

An article, method of using, and method of making a multilayer optical film comprising an optical stack, wherein the optical stack comprises a plurality of first optical layers, each first optical layer comprising a melt-processible copolymer comprising interpolymerized monomers of tetrafluoroethylene, with the proviso that the melt-processible copolymer is not fluorinated ethylene-propylene copolymer or a perfluoroalkoxy resin; and a second polymer layer disposed in a repeating sequence with the plurality of first optical layers, each second optical layer comprising a non-fluorinated polymeric material selected from the group consisting of poly(methyl methacrylate); copolymers of poly(methyl methacrylate); polypropylene; copolymers of polypropylene; polystyrenes; copolymers of styrene; polyvinylidene chloride; polycarbonates; thermoplastic polyurethanes; copolymers of ethylene; cyclic olefin copolymers; and combinations thereof is described.
