Abstract
An orifice surface is provided with a coating. A molecule for forming the coating is bonded to the orifice surface through a silicon-carbon bond. The molecule constituting the coating comprises exactly one fluoro-atom. A print head is provided with such orifice surface. In addition, a methods of manufacturing such orifice surface and a method of printing using a print head provided with such orifice surface are disclosed.
Claims10
An orifice surface comprising:
- silicon;
- at least one orifice, said at least one orifice being arranged in the orifice surface for ejecting droplets of a fluid;
- and
- a coating,
- wherein a molecule constituting the coating is bonded to the orifice surface through a silicon-carbon bond,
- wherein the molecule constituting the coating comprises exactly one fluoro-atom,
- wherein the molecule constituting the coating has a bonding end and a repellent end,
- wherein the bonding end comprises a carbon atom that is bonded to a silicon atom of the orifice surface through the silicon-carbon bond, and
- wherein the fluoro atom is positioned at a terminal carbon atom of the molecule, different from the carbon atom at the bonding end.
