Nozzles for ink jet printers can be prepared by techniques such as etching single crystal silicon, drawing fine glass tubes, drilling holes in metal sheets, etc. Many ink formulations have lower surface energies than the nozzles used with them. These inks tend to spread on the face of the nozzle. To prevent this, the high-surface energy silicon nozzles can be coated with low-surface energy coatings. However, it is difficult to get these coatings to last.
