▎ 摘　　要

NOVELTY - The method involves using (1) carbon powder and metal powder of nanosized as raw material. The graphite stick adhesive is put with powder to make a pasty mixture. A laser beam emitted from a laser is used (3) to bombard a side surface of a hollow cylindrical solid target. The hollow cylindrical solid target product is collected (4) to obtain long carbon nanotubes. USE - Manufacturing method of ultra-long carbon nanotubes and super-large-area graphene. ADVANTAGE - Manufacturing method of ultra-long carbon nanotubes and super-large-area graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a device form manufacturing ultra-long carbon nanotubes and super-large-area graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the process of the manufacturing of the ultra-long carbon nanotubes and super-large-area graphene.
