Abstract: Improved formulations of electrophoretic media that can be incorporated into displays, front plane laminates, inverted front plane laminates, or color changing films. The formulations include a non-polar fluid, a plurality of first charged particles, and charge control agents (CCA) including a quaternary amine and an unsaturated polymeric tail comprising monomers of at least 10 carbon atoms in length. The formulations show improved switching speeds, as well as a larger dynamic range at low temperatures (i.e., below about 0° C.), where compared to state-of-the-art electrophoretic media.

Abstract: Remarkably, disclosed herein is a solvent-less chemical vapor deposition (CVD) method for the oxidative polymerization and deposition of thin films of electrically-conducting polymers. In a preferred embodiment, the method provides poly-3,4-ethylenedioxythiophene (PEDOT) thin films. In other embodiments, the method is applicable to polymerization to give other conducting polymers, such as polyanilines, polypyrroles, polythiophenes and their derivatives. The all-vapor technique uses a moderate substrate temperature, making it compatible with a range of materials, including as fabric and paper. In addition, this method allows for the coating of high surface-area substrates with fibrous, porous and/or particulate morphologies. The coated substrates may be used in organic semiconductor devices, including organic light-emitting diodes (OLEDs), photovoltaics, electrochromics, and supercapacitors.

Abstract: A waveguide structure includes a substrate. A layer of high index material includes polysilane, which is patterned using a UV light source to form a waveguide.
