Abstract:
An electronically switchable privacy films suitable for use in display devices are described. The electronically switchable privacy film comprises a pair of mutually opposing transparent electrodes; an optically transparent microstructured layer disposed between the transparent electrodes, the microstructured layer comprising a plurality of microstructured ribs extending across a surface thereof such that the microstructured ribs form an alternating series of ribs and channels; and electronically switchable material disposed in the channels, the electronically switchable material being capable of modulation between high and low absorption states upon application of an electric field across the transparent electrodes.
Abstract:
Surface-modified adhesives may be prepared by contacting an adhesive layer to an at least partially discontinuous layer on a releasing substrate and removing the adhesive layer such that at least a portion of the at least partially discontinuous layer adheres to the adhesive surface. The modified adhesive surface remains an adhesive surface. The modified adhesive layer can be used to prepare adhesive articles, including articles containing multiple surface-modified adhesive layers.
Abstract:
The present application is directed to a hardcoat film article comprising a cured hardcoat layer disposed on a release liner, and a thermoplastic layer on the cured hardcoat layer opposite the release liner. The thermoplastic layer has a thickness of at least about 25 micrometers. In other embodiment, the thermoplastic layer is opaque. The release liner comprising a release material formed by irradiating a release material precursor. Additionally, this application is directed to a method of forming a composite film comprising providing a release liner, coating a hardcoat composition onto the release liner to form a hardcoat layer, and curing the hardcoat layer to form a cured hardcoat layer. A thermoplastic layer is disposed onto the cured hardcoat layer to form a hardcoat composite film, and the hardcoat composite film is attached to an adhesive layer opposite the cured hardcoat layer.
Abstract:
A transparent conductive article includes a transparent substrate, a thin electrically conductive grid, and a carbon nanolayer. The grid is disposed on the substrate, and the carbon nanolayer is also disposed on the substrate and in contact with the grid. The conductive grid and the carbon nanolayer may have thicknesses of no more than 1 micron and 50 nanometers, respectively. The carbon nanolayer has a morphology that includes graphite platelets embedded in nano-crystalline carbon, and can be produced with a buffing procedure using dry carbon particles without substantially damaging the grid structure. The article may have a visible light transmission of at least 80%, and a sheet resistance less than 500 or 100 ohms/square. The transparent substrate may comprise a flexible polymer film. The disclosed articles may substantially maintain an initial sheet resistance value when subjected to flexing.
