  • Patent number: 9266261
    Abstract: Flexible nanocrystalline cellulose films (NCC) include a polymer while retaining the property of tunable color. Polymers, for example PVOH and SB-latex, are effective in increasing the flexibility of the NCC films. The NCC film made with PVOH retains the iridescence better than that made with SB-latex; however, the NCC film made with SB-latex has a better tensile strength. In addition, the NCC film made with PVOH was found to disperse easily in water while the NCC film made with SB latex does not disperse in water (it is strongly water resistant). The color of NCC film made with PVOH and SB-latex can still be tuned with techniques that provide for tuning.

An image is viewable from the regions of the high refractive index layer, either, covertly by placed an index matched item over the device or, overtly, through selection of the thickness of the high refractive index layer.

  • Publication number: 20150103529
    Abstract: Methods and materials capable of controlling the type and relative amounts of reflectance (e.g., specular vs. diffusive reflection) in reflective coatings, especially for inclusion in a lighting fixture or other lighting source. A method of forming a reflective coating on a substrate includes applying to the substrate a precursor material that comprises a cross-linkable binder resin, a cross-linking agent, and scattering pigment particles. The pigment particles are predominantly at or near an outer surface of the applied precursor material. Thereafter, the applied precursor material undergoes a single or multistep cure to form the reflective coating by cross-linking the binder resin. The cure energy level and duration inhibit migration of the pigment particles and/or the binder resin in the applied precursor material so that the pigment particles remain predominantly at or near an outer surface of the reflective coating.

  • Publication number: 20150104569
    Abstract: Provided is High Productivity Combinatorial (HPC) testing methodology of semiconductor substrates, each including multiple site isolated regions. The site isolated regions are used for testing different compositions and/or structures of barrier layers disposed over silver reflectors. The tested barrier layers may include all or at least two of nickel, chromium, titanium, and aluminum. In some embodiments, the barrier layers include oxygen. This combination allows using relative thin barrier layers (e.g., 5-30 Angstroms thick) that have high transparency yet provide sufficient protection to the silver reflector. The amount of nickel in a barrier layer may be 5-10% by weight, chromium—25-30%, titanium and aluminum—30%-35% each. The barrier layer may be co-sputtered in a reactive or inert-environment using one or more targets that include all four metals. An article may include multiple silver reflectors, each having its own barrier layer.

  • Publication number: 20150093515
    Abstract: A fully additive method for forming optical waveguides and devices, such as thermo-optic polymer switches and electro-optic polymer modulators, is disclosed. A first polymer material of refractive index N1 is coated onto a suitable substrate to form a first cladding layer. The first cladding is then selectively patterned using a mold to form an impression of the waveguide core into the first cladding layer. Next, a core layer is formed by ink-jet printing onto the imprinted first cladding layer with a core material of refractive index N2 (N2>N1). The core layer is subsequently coated by ink jet printing with a second polymer material of refractive index N3 (N3<N2) to form a second cladding, resulting in an optical waveguide. An electrode may be ink jet printed before coating the first cladding material or after coating the second cladding material, or both before and after coating, in order to form active photonic devices.
