Title:
TAPELIKE MATERIAL CONTAINING CARBON NANOTUBE AND PRODUCTION METHOD FOR CARBON NANOTUBE AND ELECTRIC FIELD EMISSION TYPE ELECTRODE CONTAINING THE TAPELIKE MATERIAL AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2004/002889
Kind Code:
A1
Abstract:
A uniform, high-density tapelike material containing a high-purity, multi-layer or single-layer carbon nanotube, and a production method for a high-purity, multi-layer or single-layer carbon nanotube, and a high-performance electric field emission type electrode containing that tapelike material and a production method for this electric field emission type electrode. When a carbon nanotube is synthesized by arc-discharging, a hollow electrode (11) is used as an anode electrode to generate arc between the hollow electrode (11) and a cathode electrode (2) consisting of a carbon material, while an inert gas or a mixture gas containing an inert gas is being sprayed from the interior (11a) of the hollow electrode (11) toward the cathode electrode (2) to form an arc discharge path along the gas flow, whereby a high-purity carbon nanotube can be produced with the irregular movement of a cathode spot prevented. In addition, when the relative position of the both electrodes is moved to move the cathode spot of the arc (3) on a cathode material, a tapelike carbon nanotube is sysnthesized.
