Abstract:
1. A liquid discharge apparatus for discharging a disperse liquid containing a plurality carbon nanotubes, the carbon nanotubes having a length and a diameter, the liquid discharge apparatus comprising: a nozzle having an entrance and a discharge opening through which the disperse liquid containing the carbon nanotubes is discharged; an electrothermal converter for discharging the disperse liquid as an independent droplet from the discharge opening by applying energy to the disperse liquid and generating bubbles in the disperse liquid; and a controller to apply electrical energy to the electrothermal converter, wherein the controller is configured to: the nozzle being tapered in such a manner that a diameter of the nozzle decreases from the entrance towards the discharge opening, and wherein the diameter of the entrance is larger than the length of the carbon nanotubes, and the diameter of the discharge opening is larger than the diameter of the carbon nanotubes and smaller than the length of the carbon nanotubes.
