▎ 摘 要
NOVELTY - A carbon nanotube nest structure comprises nest-shaped tube which consists of multiple layers which edge part closed for each layer shorter than tube is included in inside of tube which consists of graphene in series. USE - A carbon nanotube nest structure. ADVANTAGE - The structure can acquire short carbon nanotube by simple method. DESCRIPTION OF DRAWING(S) - The drawing shows an explanatory view of the carbon nanotube nest structure. Carbon nanotube of outer layer (1) Nest-shaped carbon nanotube of first stage (2) Nest-shaped carbon nanotube of second stage (3)
