▎ 摘  要

NOVELTY - The method comprises placing a graphene under reduced pressure of 100-1 mbar, and providing energy to the graphene to form an open-ended single-wall carbon nanotube. The step of providing energy to the graphene comprises heating the graphene to a temperature of 200-600 degrees C by providing radiant heat, induction heat or microwave heat. The nanotube is open ended on both ends. USE - The method is useful for producing an open-ended single-wall carbon nanotube. ADVANTAGE - The method is capable of energy-efficiently producing the open-ended single-wall carbon nanotube with homogeneous length, good homogeneity in chirality and high yield and without requiring expensive equipment. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of an open end of a nanotube at a higher magnification.
