    Abstract: Electrically conductive and abrasion resistant polymeric compositions, methods of fabrication thereof and uses thereof are described. Admixtures of abrasion resistant materials and electrically conductive polymeric materials are formed. Many of these admixtures are light transmitting and can be used as an abrasion resistant light transmitting electrostatic discharge layers. The light transmitting discharge layer is useful as a surface coating for visual displays such as CRT screens to avoid electrostatic accumulation of dust and scratching. The compositions can be admixtures of abrasion resistant silicones, polysiloxanes, acrylates, epoxies, methacrylates, epoxyacrylates, epoxymethacrylates, styrenes and electrically conductive polymers selected from the group of substituted and unsubstituted polyanilines, polyparaphenylenevinyles, substituted and unsubstituted polythiophenes substituted and unsubstituted poly-p-phenylene sulfides, substituted and unsubstituted polyfuranes, substituted and unsubstituted polypyrroles, substituted and unsubstituted polyselenophenes, polyacetylines formed from soluble precursors, combinations thereof and blends thereof with other polymers. The compositions can be a layer of an electrically conductive polymer with an abrasion resistant layer thereover.

    Abstract: An improved apparatus and process are described in which a direct negative is formed using commercially available multi-stylus recording heads. A negative precursor comprised of a transparent support and an opaque thermoplastic ink layer carried thereon, is brought into contact with an ink receiving medium comprised of a resistive layer and a thin conductive ink receiving layer thereon. Electrical currents are provided by the recording styli of the multi-stylus recording head to the resistive layer to provide sufficient heat to soften regions of the opaque ink brought into contact with the conductive layer, by which regions of said opaque ink are transferred to the ink receiving conductive layer. In this manner, a pattern of opaque ink regions is removed from the surface of said transparent support, whereby a direct negative is formed having light opaque and light transparent regions.

    Abstract: Electroerosion recording materials for "direct negative" and "offset master" are provided with a surface protective coating of solid conductive lubricant dispersed in a hydrophilic, crosslinked polymeric matrix. The protective films are especially useful where direct offset masters are produced without removal of non-eroded lubricant film.The recording medium of this invention provides use as a defect-free "direct negative" and/or "direct offset master", without requiring the removal of the overlayer prior to use on the printing press. The protective coatings are applied from aqueous dispersions of polymer-particulate compositions and thus avoiding the use of organic solvents.

    Abstract: Techniques for increasing conductivity of graphene films by chemical doping are provided. In one aspect, a method for increasing conductivity of a graphene film includes the following steps. The graphene film is formed from one or more graphene sheets. The graphene sheets are exposed to a solution having a one-electron oxidant configured to dope the graphene sheets to increase a conductivity thereof, thereby increasing the overall conductivity of the film. The graphene film can be formed prior to the graphene sheets being exposed to the one-electron oxidant solution. Alternatively, the graphene sheets can be exposed to the one-electron oxidant solution prior to the graphene film being formed. A method of fabricating a transparent electrode on a photovoltaic device from a graphene film is also provided.

    Abstract: Graphene transistor devices and methods of their fabrication are disclosed. In accordance with one method, a resist is deposited to pattern a gate structure area over a graphene channel on a substrate. In addition, gate dielectric material and gate electrode material are deposited over the graphene channel and the resist. Further, the resist and the electrode and dielectric materials that are disposed above the resist are lifted-off to form a gate structure including a gate electrode and a gate dielectric spacer and to expose portions of the graphene channel that are adjacent to the gate structure. Additionally, source and drain electrodes are formed over the exposed portions of the graphene channel.
