    Abstract: The invention provides the use of a solvent selected from the group consisting of alkoxybenzenes and alkyl substituted alkoxybenzenes in reducing the contact resistance in an organic thin film transistor comprising a semiconductor layer comprising a blend of a small molecule semiconductor material and a polymer material that is deposited from a solution of said small molecule semiconductor material and said polymer material in said solvent and novel semiconductor blend formulations that are of particular use in preparing organic thin film transistors. Said solvents yield devices with lower absolute contact resistance, lower absolute channel resistance, and lower proportion of contact resistance to the total channel resistance.

  • Patent number: 9057892
    Abstract: A thermochromatic element includes a sealed enclosure, an insulation layer and a first heating element. The insulation layer is received in the sealed enclosure, that divides the sealed enclosure into a first chamber and a second chamber. The first heating element is configured to heat the first chamber. The first heating element includes a carbon nanotube film including a number of carbon nanotube linear units and a number of carbon nanotube groups. Each carbon nanotube linear unit includes a number of first carbon nanotubes substantially oriented along a first direction, and are spaced from each other and substantially extending along the first direction. The carbon nanotube groups are combined with the carbon nanotube linear units by van der Waals force. The carbon nanotube groups between adjacent carbon nanotube linear units are spaced from each other in the first direction.

  • Publication number: 20150115208
    Abstract: The ink of the present invention is an oil dispersion of pigment particles. The pigment particles are designed to have no or insignificant response to applied electric fields. The ink comprises a carrier liquid having a concentration of pigment particles disposed in the carrier liquid. A surfactant is included in the carrier liquid, wherein the surfactant is adsorbed on the pigment particles only when activated. The pigment particles having adsorbed the surfactant do not generate a reactive level of particle charge so that the pigment particles move with and not independently from the carrier liquid under an applied electrical field. The surfactant is activated by the application of at least one of heat and solvent to the carrier liquid so that the surfactant molecules adsorb onto the pigment particles.

  • Patent number: 9018299
    Abstract: An object of the present invention is to provide a colored liquid with superior separability from polar solvents for use with an electrowetting or electrofluidic device that uses a coloring agent added as a colorant to a nonpolar solvent. A colored liquid according to the present invention contains a nonpolar solvent and a colorant, and the colorant is a modified pigment containing a pigment (A) and a polymer (P) formed on a surface thereof by polymerizing a polymer (B) soluble in a nonaqueous solvent and at least one polymerizable unsaturated monomer (C) that is soluble in the nonaqueous solvent and that becomes insoluble or poorly soluble in the nonaqueous solvent after polymerization. A multi-phase liquid colored composition according to the present invention contains the colored liquid and a polar solvent immiscible with the colored liquid.

  • Patent number: 9011734
    Abstract: Ligand exchange of thermochromic, LETC, systems exhibiting a reversible change in absorbance of electromagnetic radiation as the temperature of the system is reversibly changed are described. The described LETC systems include one or more than one transition metal ion, which experiences thermally induced changes in the nature of the complexation or coordination around the transition metal ion(s) and, thereby, the system changes its ability to absorb electromagnetic radiation as the temperature changes.

  • Patent number: 9011727
    Abstract: Blending an electrically active, anodically coloring, electrochromic polymer with a non-electrochromic, non-electrically conductive binder polymer greatly enhances the performance of the anodically coloring, electrochromic polymer in an electrochromic device over time. In addition to improved physical characteristics of the blend, e.g., film build, durability etc, the coloristic properties, including color space and color strength, of the device comprising the blend are more durable than when using the neat polymer, and in certain instances, the color space and color intensity provided by the blend is superior to that available from the neat polymer.

  • Patent number: 8986572
    Abstract: The invention is directed to calcium fluoride crystal optics with improved laser durability that can be used for the transmission of below 250 nanometer (nm) electromagnetic radiation. The optics consists of CaF2 as the major component and Mg in an amount in the range of 13 ppm to 20 ppm while Ce and Mn are <0.5 ppm. The doped crystal and optics made therefrom have a ratio of 515/380 nm transmission loss of less than 0.3 after exposure to greater than 2.8 MRads of ?-radiation. Further, the doped crystal and optics made therefrom exhibit a greatly improved lifetime as shown by ALDT testing to at least 1 billion pulses.
