ナノカーボンの製造方法、ナノカーボンの製造装置、ナノカーボンのパターン化方法
Document Type and Number:
Japanese Patent JP3602092
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method and a device for manufacturing an electron emission source by instantaneously transforming a surface of an arc discharged material consisting mainly of graphite into nano carbon by an arc discharge which does not necessarily require process vessels and the like but a welding arc torch or a similarly structured device and a method and a device for manufacturing a patterned electron emission source by transforming a part or parts of the surface of the arc discharged material into nano carbon. SOLUTION: A torch electrode 10 of an arc torch 1 which is the first electrode and an arc discharged material 2 using a graphite plate which is the second electrode are placed in the air facing each other. An arc discharge is generated by impressing electric potential between the torch electrode 10 and the arc discharged material 2. The graphite of the predetermined part of the material 2 is transformed into nano carbon by an arc discharge.
