METHOD FOR MANUFACTURING CARBON NANOTUBE EMITTER FOR EMITTING ELECTRIC FIELD

摘要

PURPOSE: A method is provided to effectively prevent a carbon nanotube film from being stripped off during surface treatment of the carbon nanotube film by increasing the strength of the carbon nanotube film. CONSTITUTION: A method comprises a step of producing a paste by mixing powder of a carbon nanotube(410) and a silicon based polymer(450); a step of arranging a cathode(300); a step of forming a carbon nanotube film(400) by depositing the paste on the cathode; a step of hardening the silicon based polymer by heat treating the carbon nanotube film; and a step of guiding the end of the carbon nanotube in such a manner that the end is exposed from the surface of the carbon nanotube film, by surface treating the carbon nanotube film.
