Abstract
A process for preparing an ink jet print head front face or nozzle plate having a textured superoleophobic surface comprising providing a silicon substrate; using photolithography to create a textured pattern in the silicon substrate; optionally, modifying the textured silicon surface by disposing a conformal oleophobic coating thereon; and forming an ink jet print head front face or nozzle plate from the textured oleophobic silicon material to provide an ink jet print head front face or nozzle plate having a textured superoleophobic surface.
Claims15
A process for preparing an ink jet print head front face or nozzle plate having a textured superoleophobic surface comprising:
- providing a silicon substrate;
- using photolithography to create a textured pattern in the silicon substrate;
- wherein the textured pattern comprises a groove pattern having a total height of about 0.5 to about 5 micrometers;
- or
- wherein the textured pattern comprises an array of pillars having a pillar height of about 0.5 to about 5 micrometers;
- and
- modifying the textured silicon surface by disposing a conformal oleophobic coating thereon;
- and
- forming an ink jet print head front face or nozzle plate from the textured oleophobic silicon material to provide an ink jet print head front face or nozzle plate having a textured superoleophobic surface.
An ink jet print head front face or nozzle plate having a textured superoleophobic surface comprising:
