20090308753 | Methods for controlling silica deposition onto carbon nanotube surfaces - The invention provides a method of controlling the rate of noncovalent silica deposition onto at least one carbon nanotube. The method comprises (a) providing a one chamber electrochemical cell comprising a working electrode comprising at least one carbon nanotube; a reference electrode; a counter electrode; supporting electrolytes; and a reagent solution, wherein the reagent solution comprises a precursor of silica; and (b) applying a selected negative potential to the working electrode, wherein the rate of silica deposition onto the at least one carbon nanotube increases as the potential becomes more negative. | 12-17-2009 |
20110039196 | DIGITAL ELECTROSTATIC LATENT IMAGE GENERATING MEMBER - Embodiments pertain to a novel imaging member, namely, an electrostatic latent image generating member that can generate an electrostatic latent image digitally without using a raster output scanner (ROS), photoreceptor and charger. The imaging member facilitates the charge injection process between an organic conjugated polymer and N,N′-diphenyl-N,N′bis(3-methylphenyl)-[1,1′-biphenyl]-4,4′diamine charge transport layer. | 02-17-2011 |
20110039201 | DIGITAL ELECTROSTATIC LATENT IMAGE GENERATING MEMBER - Provided are electrostatic latent image generators, printing apparatuses including the electrostatic latent image generators, and methods of forming an electrostatic latent image. The electrostatic latent image generator can include a substrate and an array of pixels disposed over the substrate, wherein each pixel of the array of pixels can include a layer of one or more nano-carbon materials, and wherein each pixel of the array of pixels is electrically isolated and is individually addressable. The electrostatic latent image generator can also include a charge transport layer disposed over the array of pixels, wherein the charge transport layer can include a surface disposed opposite to the array of pixels, and wherein the charge transport layer is configured to transport holes provided by the one or more pixels to the surface. | 02-17-2011 |
20120037026 | ELECTROSTATIC DIGITAL OFFSET/FLEXO PRINTING - Various embodiments provide systems and methods for digital offset/flexo printing by selectively addressing one or more hole-injecting pixels of a nano-enabled imaging member to form a latent image thereon, wherein the latent image can be electrostatically developed with an ink and then transferred from the nano-enabled imaging member onto a print media. | 02-16-2012 |
20120281052 | DIGITAL MARKING USING A BIPOLAR IMAGING MEMBER - Various embodiments provide materials and methods for direct digital marking, wherein a surface charge contrast can be formed by oppositely addressing adjacent charge injection pixels of a bipolar imaging member and developed with enhanced image contrast at a reduced voltage of the transistors. | 11-08-2012 |
20130092038 | APPARATUS FOR DIGITAL FLEXOGRAPHIC PRINTING - A digital flexography system includes an imaging member with a charge generating layer formed from an array of addressable pixels and a charge transport layer thereon. Ink is delivered to the imaging member using a simple rough donor roll, rather than an anilox roll. Instead of controlling the amount of ink delivered using the anilox roll, the amount of ink is controlled by the pixels on the imaging member. | 04-18-2013 |
20130135391 | MULTI-FILM ADHESIVE DESIGN FOR INTERFACIAL BONDING PRINTHEAD STRUCTURES - In accordance with aspects of the present disclosure, a printhead assembly arranged to dispense ultraviolet curable ink or gel ink and method thereof is disclosed. The printhead assembly includes a plurality of functional plates stacked together; a first adhesive layer arranged between adjacent functional plates to provide bonding between the plates; and a second adhesive layer arranged between adjacent function plates to provide chemical resistance to the ultraviolet curable ink or the gel ink. | 05-30-2013 |
20130338293 | FUSER MEMBER - A fuser member includes a surface layer comprising a fluoroelastomer-perfluoropolyether composite formed from a reaction mixture comprising a fluoroelastomer and a perfluoropolyether compound. Methods of manufacturing the fuser member and printing systems comprising the fuser member are also disclosed. | 12-19-2013 |
