Abstract: The present disclosure provides an article including a layer having a nanostructured first surface including nanofeatures and an opposing second surface, and an organic layer including a major surface attached to a portion of the nanofeatures. The nanostructured first surface includes protruding features that are formed of a single composition and/or recessed features. The nanofeatures and the major surface of the second layer together define at least one void. The present disclosure also provides a method of making the article including contacting nanofeatures of a layer having a nanostructured surface with a major surface of an organic layer and reacting at least one material to secure the two layers together. In addition, the present disclosure provides an optical information display and an OLED device including the article. The nanostructured surface of the article is protected from damage and contamination by the organic layer.

Abstract: A method of making surface-functionalized transition metal oxide nanoparticles comprises: providing a sol comprising transition metal oxide nanoparticles dispersed in an aqueous liquid medium having a pH of less than or equal to 3.5, combining the sol with an extractant composition comprising at least one carboxylic acid and at least one organic amine, and a water-immiscible organic solvent, and separating at least a portion of the organic phase from the aqueous phase and then at least partially removing the water-immiscible organic solvent. The carboxylic acid has from 6 to 30 atoms. The organic amine is represented by the formula R2R3NH, wherein R2 is a hydrocarbyl group having from 6 to 30 carbon atoms, and R3 is H or an alkyl group having from 1 to 4 carbon atoms. The at least one organic amine is present in an amount sufficient raise the pH to at least 5, thereby forming discrete separable aqueous and organic phases. A surface-modified nanoparticle composition, a curable composition and an article comprising the same are also disclosed.

Abstract: A composition is described comprising a styrene-isobutylene block copolymer; and at least one ethylenically unsaturated monomer. After curing the composition comprises polymerized units of the ethylenically unsaturated monomer. In some embodiments the ethylenically unsaturated groups are selected from (meth)acryl or vinyl ether. The composition is suitable for use as a (e.g. pressure sensitive) adhesive. Articles, methods of making an article, and methods of bonding are also described.

Abstract: Curable, coatable compositions include silane surface-treated inorganic nanoparticles with a high refractive index, and a curable reaction mixture. The curable reaction mixture includes a first (meth)acrylate monomer comprising a high refractive index (meth)acrylate monomer with a refractive index of 1.6 or higher, a second (meth)acrylate monomer comprising a lower refractive index (meth)acrylate monomer with a refractive index of less than 1.6, and at least one initiator. Cured optical coatings prepared from the compositions are optically clear, having a visible light transmission of at least 88% and a haze of 5% or less, and have a refractive index of at least 1.78, and are capable of passing a 10 millimeter mandrel flexibility test.

Abstract: A light directing film includes a structured major surface with a plurality of microstructures extending along a first direction. Each microstructure has a first region and a second region different from the first region, a substantially constant height in the first region and a non-constant maximum height in the second region greater than the substantially constant height in the first region, and a same lateral cross sectional shape in the first region and the second region.
