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.
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.

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.
