TECHNOLOGY FOCUS - POLYMERS - Preferred Components: In the applicator, the structured surface film dispenser comprises an application member for applying pressure to the structured surface film, where the application member is a bar or a roller. The applicator is in combination with a structured surface film, where the film comprises a tooling film or riblets, and where the structured surface film comprises a nano-scale antireflection surface, where the structured surface film comprises a matte surface for diffusing light. Also, the applicator is in combination with at least one reactive flowable material provided within the flowable material dispenser, and comprising a wetting aid provided within the flowable material dispenser, and an adhesive provided within the flowable material dispenser. Likewise, the applicator is in combination with at least one flowable material that exhibits a dual-cure mechanism, and in combination with at least two flowable materials, where a first flowable material comprises an isocyanate and a second flowable material comprises a polyol. Moreover, the applicator is in combination with a carbon dioxide permeable film, and in combination with at least one flowable material selected from a polyol, polyol with dibutyl tin dilaurate catalyst, UV absorber and hindered amine light stabilizer, multifunctional isocyanate, silicone elastomer, moisture cure silicone, silicone containing a radiation sensitive photo initiator, silicone SPOx, epoxide, PDMS adhesive, soap and water, alcohols, alcohol and water mixtures, and a wetting aid. The applicator is in combination with at least one structured surface film where the film comprises a material selected from water soluble polymers, and water swellable polymers. The applicator is in combination with a structured surface film, where the film comprises a polyolefin, in combination with a structured surface film having a higher moisture vapor transmission rate than polyolefin, in combination with at least one structured surface film where the film comprises a material selected from polyamides, polylactic acids, thermally induced phase separation membranes, polyethylene terephthalates, ethylene/octenes, ethylene/hexenes, other ethylene copolymers, and poly(methyl methacrylates), in combination with at least one structured surface film where the film comprises a material selected from polyurethanes, polyureas, polyvinyl alcohols, polyvinyl acetates, polyalkylene oxides, polyacrylic acids, propylene copolymers with polar comonomers, and microporous membranes including thermally induced phase separation membranes, and in combination with a structured surface film, where the structured surface film comprises a structured surface facing away from the substrate when dispensed. The film comprises an adhesive on the surface opposite that of the structured surface. Preferred Method: Providing the structured surface further comprises distributing the flowable material across substantially the width of the structured surface film; priming the substrate; and removing the structured surface film to provide a structured surface on the substrate. The flowable material is an adhesive. The substrate is selected from a photovoltaic panel, a solar thermal panel, a turbine blade, an automobile component, a plane component, a boat component, a window, a train component, and a human powered vehicle component.
