摘要:
A method of making 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:
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:
A coating for an ink jet printhead front face, wherein the coating comprises a low adhesion coating, wherein when the low adhesion coating is disposed on an ink jet printhead front face surface, jetted drops of ultra-violet gel ink or jetted drops of solid ink exhibit a low sliding angle with the printhead front face surface, wherein the low sliding angle is less than about 1° to less than about 30°. In embodiments, the low adhesion coating is an oleophobic coating that exhibits a contact angle of greater than about 35° with ultra-violet gel ink or solid ink.
