NOVELTY - Continuously producing a polymeric object (159), involves providing a continuously moving mold (30) having a complex pattern of microstructures or nanostructures formed on a portion of a mold surface; depositing a polymeric powder comprising thermosetting or thermoplastic resin on the moving mold surface; melting the powder to create a polymeric object having a complex pattern on a surface of object, where the complex pattern on the polymeric object is complementary to the complex pattern on mold surface; and removing polymer object from the mold.    USE - For continuously producing polymeric object e.g. polymeric film (claimed) useful for optical applications, such as lenticular lenses, Fresnel lenses, light guides, diffusers, retro-reflective films, micro-lens arrays, brightness enhancement film (BEF), LED arrays, biomedical components, solar concentrators, micro-fluidic products, tissue culture media, micro-electrical-mechanical devices (MEMS), micro-acoustical devices, chemical mechanical planerization (CMP), and fuel cells.    ADVANTAGE - The method reduces mold cost and fabrication time, and provides faster scale-up and commercialization from higher manufacturing speed than the prior art. The method allows the use of a wider range of materials than the prior art, including both thermoplastic and thermoset polymers, optionally loaded with other second phase or filler materials such as, for example, ceramic, glass or metal powders. The method has the ability to microform materials that can withstand higher use temperatures or that become polymer composites, having improved mechanical, electrical or optical properties which are of significant benefit for some end use applications, beyond the narrow range of typically used polymers. The method has great utility in forming complex patterns of precise optical configuration in relatively small macrostructures, in the range of 1-10 mm. The method avoids the viscosity and surface tension limitations of hot-polymer or liquid replication found in embossing or casting techniques which can require pushing the polymaterial into mold cavities. The method allows elimination of pigments and adhesion promoters thus permitting conventional powder coating apparatus to electro-deposit pure powdered polymer on to molds.    DETAILED DESCRIPTION - Continuously producing a polymeric object (159) having a complex pattern formed on a surface of the object, where the complex pattern comprises elements of predetermined microstructured or nano-structured dimensions, involves providing a continuously moving mold (30) having a complex pattern of microstructures or nanostructures formed on at least a portion of a surface of a mold; depositing a polymeric powder comprising either a thermosetting or thermoplastic resin on the moving mold surface; melting the powder to create a polymeric object having a complex pattern on a surface of object, where the complex pattern on the polymeric object is complementary to the complex pattern on mold surface; and removing polymer object having complex pattern from the moving mold. The polymeric powder is free of additives. The polymeric powder further comprises a further phase or filler material. The object is a continuous film having a first layer and a second layer. The method further involves adhering a second layer of polymeric material to second side of the first layer. The particle size of polymer powder is sufficiently small so that the particles fill the recesses of complex pattern in mold surface from the bottom up so as substantially to avoid any air entrapment. The mold surface provides a through-hole (67) in the polymeric object. The polymeric powder is provided directly from a polymerizing process.
