Abstract: A light extraction film having nanoparticles with engineered periodic structures. The light extraction film includes a substantially transparent substrate, low index one-dimensional or two-dimensional periodic structures on the substrate, and a high index planarizing backfill layer applied over the periodic structures. Light scattering nanoparticles are either applied in a layer over the periodic structures or included in the backfill layer.

Abstract: Light control films, and a method for manufacturing tools used to microreplicate light control films.

Abstract: An optical film having a substrate and microreplicated features on a major surface of the substrate. The features include microreplicated macro-scale features and one or more microreplicated diffractive features on the macro-scale features. The films can be made from work pieces machined with tool tips having diffractive features. The tool tip forms both the macro-scale features and diffractive features while machining the work piece. A coating process can then be used to make the optical films from the machined work piece.

Abstract: A fluoropolymer coating composition contains a homogeneous mixture of crystalline submicron fluoropolymer particles dispersed in a solvent-borne solution of less crystalline or amorphous fluororesin. The composition may be prepared by blending a latex containing crystalline submicron fluoropolymer particles with a latex containing less crystalline or amorphous fluororesin particles, coagulating and drying the blended latices, and dissolving the dried blend in a solvent for the fluororesin particles. Quasi-homogenous compositions may be prepared by blending dry crystalline submicron fluoropolymer particles with a) dry less crystalline or amorphous fluororesin particles and a solvent for the fluororesin particles, or b) a solvent-borne solution of less crystalline or amorphous fluororesin. Rubbing the disclosed coatings can provide a thin, continuous or nearly continuous fluoropolymer surface layer atop a less crystalline or amorphous fluororesin binder containing crystalline submicron fluoropolymer particles.

Abstract: A thermal transfer donor element is provided which includes a support, light-to-heat conversion layer, interlayer, and thermal transfer layer. When the donor element is brought into contact with a receptor and imagewise irradiated, a portion of the transfer layer is transferred to the receptor. The relative surface texture of the layers can be at least partially controlled, prior to imaging of the donor element, for desired effects in the resulting receptor device. The construction and process of the donor element is useful in making colored images including applications such as color proofs, color filter elements, and organic light emitting displays.

Abstract: Method of forming a very hydrophobic, extremely hydrophobic or superhydrophobic surface comprising depositing a composition comprising hydrophobic microparticles, hydrophobic nanoparticles, or a mixture thereof and a binder in sufficient quantity to provide a hydrophobic or a superhydrophobic surface on a substrate having a micropatterned surface having raised portions, recessed portions or a combination thereof.

Abstract: The present invention includes ultraviolet curable compositions preferably containing discrete, crystalline zirconia nanoparticles with reactive, or copolymerizable, surface modification, in a polymerizable monomer/oligomer resin mixture. It is believed that copolymerizable surface modification provides a functional group that enables the functionalized particle to co-polmerize with the reactive monomers, oligomers, and crosslinkers in the formulation. Relative to surface modification of the nanoparticles, acrylate functionality is preferred over methacrylate functionality. On the other hand, methacrylate functionality is preferred over non-reactive, or nonpolymerizable, functionality. As the nanocomposite cures, the resultant network is heavily crosslinked by selection of raw materials with substantial acrylate functionality.

Abstract: A height referencing biochemical cassette comprising of a surface suitable to act as a coupling agent, a height referencing indicator, and molecules bonded to the surface. This cassette is a capable of use to test for bonding to these molecules through measuring the height difference between the indicator and the surface. This invention provides an efficient means to quickly and easily test for bonding of molecules to other molecules.
