US Patent 7607762 - CNT anti-wetting nozzle plate
http://www.freepatentsonline.com/7607762.html
In inkjet printers it is important for the surface of the printhead to be resistant to wetting in order to avoid misdirected ink drops from printing nozzles. This patent from Fujifilm teaches a carbon nanotube layer which provides such anti-wetting in addition to good durability. Claim 1 reads:
1. A nozzle plate comprising:
a nozzle through which liquid is ejected;
a nozzle forming surface in which the nozzle is provided; and
a liquid-repellency layer which is provided on the nozzle forming surface, the liquid-repellency layer including a carbon nanotube layer.
