Described is a process for producing an inkjet printhead comprising an aperture face having an oleophobic surface. The process includes forming an aperture plate by disposing a silicon layer on an aperture plate; using photolithography to create a textured pattern on an outer surface of the silicon layer; and chemically modifying the textured surface by disposing a conformal, oleophobic coating on the textured surface. The oleophobic aperture plate may be used as a front face surface for an inkjet printhead.
摘要:
A thermal bubble jetting device including a substrate. A superoleophobic, textured surface is positioned on the substrate. The textured surface comprises one or more gaps configured for holding a gas. A receptacle is positioned in fluid communication with the textured surface. Both an inlet and nozzle are in fluid communication with the receptacle. The device includes a heater mechanism configured to expand a gas in the one or more gaps so as to sufficiently increase pressure in the receptacle to force liquid through the nozzle.

Transparent or semi-transparent, electrically conductive anti-curl back coating composite for electrophotographic imaging member comprising a carbon nanotube complex and a polycarbonate binder are described along with processes for preparing them.
摘要:
An aperture plate for a print head of a printer can include a first layer having a first emissivity which is covered by a second layer having a second emissivity which is less than the first emissivity. In an embodiment, the second layer can be etched at nozzle locations to form openings in the second layer which have widths/areas greater than widths/areas of nozzles formed in the first layer. In another embodiment, the second layer can have a smaller thickness at the nozzle locations and a larger thickness away from the nozzle locations. Forming the openings in the second layer which are larger than the nozzles, or forming the second layer thinner at the nozzle locations prior to forming the nozzles, can provide a well-formed nozzle and an aperture plate having a low emissivity.
摘要:
An ink jet print head front face or nozzle plate having a textured superoleophobic surface that prevents undesirable drooling, wetting and/or adhesion of the ink on the print head. The textured surface includes a rim formed around the nozzle. Also described are methods for forming the textured superoleophobic ink jet print head front face or nozzle plate from silicon having the textured, oleophobic surface.
摘要:
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.

In accordance with the invention, there are xerographic photoreceptors, image forming apparatus, and methods of forming an image on image. The xerographic photoreceptor can include a substrate and a conductive ground plane having an optical transparency disposed over the substrate, the conductive ground plane including a carbon nanotube layer, such that machine cycling of the xerographic photoreceptor can produce less than approximately a 10% change in the optical transparency of the conductive ground plane after about 100,000 or more machine cycles. The xerographic photoreceptor can also include a photosensitive layer disposed over the conductive ground plane, wherein the photosensitive layer can include a charge generator material and a charge transport material.
