  • Publication number: 20170335620
    Abstract: Transfer tapes and methods of making transfer tapes are described. In one aspect, the transfer tape comprises a template layer having a structured surface; a backfill layer disposed on at least a portion of the template layer, the backfill layer having a microstructured surface opposite the structured surface; and a layer disposed adjacent the microstructured surface, wherein the layer disposed adjacent the microstructured surface has a refractive index that differs from the backfill layer. The microstructured surface together with the adjacent layer functions as a diffusive layer, or in other words a diffusive interface. Also described are microoptical glazing and methods of making microoptical glazing as well as insulated glazing units and methods of making insulated glazing units.

  • Patent number: 9780335
    Abstract: Lamination transfer films and methods for transferring a structured layer to a receptor substrate. The transfer films include a carrier substrate having a releasable surface, a sacrificial template layer applied to the releasable surface of the carrier substrate and having a non-planar structured surface, and a thermally stable backfill layer applied to the non-planar structured surface of the sacrificial template layer. The sacrificial template layer is capable of being removed from the backfill layer, such as via pyrolysis, while leaving the structured surface of the backfill layer substantially intact.

  • Patent number: 9711744
    Abstract: A transfer tape is disclosed that includes a carrier, a template layer having a first surface applied to the carrier and having a second surface opposite the first surface, wherein the second surface comprises a non-planar structured surface, a release coating disposed upon the non-planar structured surface of the template layer, and a backfill layer disposed upon and conforming to the non-planar structured surface of the release coating. In some embodiments, the backfill layer includes a silsesquioxane such as polyvinyl silsesquioxane. The disclosed transfer tape can be used to transfer replicated structures to a receptor substrate.

  • Publication number: 20160375666
    Abstract: A method of making patterned structured solid surfaces is disclosed that includes filling a structured template with backfill material to produce a structured transfer film, patternwise curing the backfill material to produce cured areas and uncured areas in the structured transfer film, and laminating the structured transfer film to a receptor substrate. The structured template is capable of being removed to form structured and unstructured backfill layers. The structured and unstructured backfill layers may then be blanket cured. The backfill layer can include at least two different materials, one of which can be an adhesion promotion layer. In some embodiments the backfill layer includes a silsesquioxane such as polyvinyl silsesquioxane. The structured transfer film is a stable intermediate that can be covered temporarily with a release liner for storage and handling.

  • Patent number: 9500888
    Abstract: An electronically switchable privacy device suitable for use in display devices is described. The electronically switchable privacy device comprises a first transparent electrode layer, an electronically switchable layer disposed adjacent to the first transparent electrode layer, and a second transparent electrode layer disposed adjacent to the electronically switchable layer and opposite the first transparent electrode layer. The second transparent electrode layer comprises a transparent substrate layer having a plurality of microstructured ribs extending across a major surface of the transparent substrate layer such that the microstructured ribs form an alternating series of ribs and channels, each channel having channel walls defined by adjacent ribs.

  • Patent number: 9472788
    Abstract: Methods for transferring nanoparticles and nanowires to permanent glass receptors using transfer films. The transfer films include nanoparticles within a sacrificial material having a structured backfill layer on a substrate and a nanowire formulation between sacrificial substrates. To transfer the nanoparticles, the transfer film is laminated to a glass receptor, the substrate is removed, and the sacrificial material is baked-out to leave the nanoparticles aligned within the structured surface of the backfill layer on the glass receptor. To transfer the nanowires, the transfer film is laminated to a glass receptor, and the sacrificial substrates are baked-out to leave the nanowires aligned on the glass receptor.
