  • Smooth surface transfuse belts and process for preparing same
    Patent number: 6709992
    Abstract: Process for preparing durable, re-usable intermediate toner image-transfer belts or electrostatic transfuse belts. The present belts have a continuous elastomer-impregnated fibrous fabric support and at least one outer smooth release layer of a cured elastomer polymer. The invention is characterized by the application of a thin primer layer of a hydrolyzable polyfunctional silicone composition between the elastomer-coated surface of the fabric support and the outer elastomer polymer layer. The polyfunctional silicone chemically-bonds to the elastomer of the fabric support during hydrolysis and chemically-bonds to the outer elastomer layer during its cure, to form a durable, heat-resistant transfuse belt. The layers maybe applied to the fabric support by spray application as dilute solutions.

    Publication number: 20030232203
    Abstract: A composition, method and use is disclosed for a porous plug that functions as an electro-osmotic pump. The polymer eliminates any back pressure effects while enhancing the electro-osmotic flow in a channel. The pump is bach fabricated by surface micromachining on top of a silicon wafer. The pump device is driven by an alternating zero-average injected current signal at low frequencies producing a bubble-free electro-osmotic flow with a reversible net movement. The device is capable of an average water-air interface velocity of 1.8 &mgr;m/second at 0.8 Hz. The velocity may be increased from between 4.8-13.9 &mgr;m/second by necking down the channel size.

    Abstract: A covered substrate is described, which comprises: (a) a flexible substrate layer; and (b) a plurality of cooperative barrier layers disposed on the substrate layer. The plurality of cooperative barrier layers further comprise one or more planarizing layers and one or more high-density layers. Moreover, at least one high-density layer is disposed over at least one planarizing layer in a manner such that the at least one high-density layer extends to the substrate layer and cooperates with the substrate layer to completely surround the at least one planarizing layer. When combined with an additional barrier region, such covered substrates are effective for enclosing organic optoelectronic devices, such organic light emitting diodes, organic electrochromic displays, organic photovoltaic devices and organic thin film transistors. Preferred organic optoelectronic devices are organic light emitting diodes.
