Abstract
The present invention provides a field emitter electrode and a method for fabricating the same. The method comprises the steps of mixing a carbonizable polymer, carbon nanotubes and a solvent to prepare a carbon nanotube-containing polymer solution, electrospinning (or electrostatic spinning) the polymer solution to form a nanofiber web layer on a substrate, stabilizing the nanofiber web layer such that the polymer present in the nanofiber web layer is crosslinked, and carbonizing the nanofiber web layer such that the crosslinked polymer is converted to a carbon fiber.
