METHOD FOR MANUFACTURING CARBON NANO WIRE

摘要

PROBLEM TO BE SOLVED: To obtain carbon nano wires W excellent in mechanical, electrical and chemical properties and used as a functional material in a wide field including a machine structural material, electronic parts and a photosemiconductor. SOLUTION: The carbon nano wires W have an atomic arrangement structure in which a series of carbon atom chains C are arranged on the central line and multiwalled carbon nanotubes M having≤1 nm diameter of the innermost shell surround the carbon atom chains C. The carbon nano wires are manufactured by evacuating a vacuum chamber 11, introducing gaseous hydrogen into the chamber 11 and causing an arc discharge between an anode 13 and a cathode 14 in an atmosphere under≤8 kPa pressure to coat a series of carbon atom chains C with multiwalled carbon nanotubes M.
