Abstract:
1. A method of fabricating a field emitter electrode, the method comprising the steps of: providing an electrolytic solution containing metal ions in an electrolytic bath; providing carbon nanotubes and a cationic dispersant for preventing the agglomeration of the carbon nanotubes in the electrolytic solution; and applying a predetermined voltage to a cathode drum and an insoluble anodic compartment, both of which are immersed in the electrolytic solution, and forming a metal film containing the carbon nanotubes on the surface of the cathode drum; wherein the step of providing the carbon nanotubes and cationic dispersant in the electrolytic solution includes: mixing the carbon nanotubes and the cationic dispersant, and pulverizing the mixture; and feeding the pulverized mixture to the electrolytic solution.
