<p>A nozzle plate for an ink jet printhead, the nozzle plate comprising the following layers in the order recited: a) a first monomolecular layer of an organic material having first and second functional groups, the first functional group of the first monomolecular layer being bound to the surface of the nozzle plate, and the second functional group of the first monomolecular layer being bound to a second monomolecular layer, and b) the second monomolecular layer of an organic material having first and second functional groups, the first functional group of the second monomolecular layer being bound to the second functional group of the first monomolecular layer, and the second functional group of the second monomolecular layer is an anti-wetting group. The coating has hydrophobic properties and can be removed and replenished by means of the cleaning solution that is used for removing ink residue from the nozzle plate. The lifetime of the coating is extended. <IMAGE></p> |
