▎ 摘　　要

NOVELTY - The method involves providing a carbon nanotube film(10). A graphene film (30)is grown on a top surface of a substrate (20). The carbon nanotube film is placed on the graphene film. The substrate is removed to form a carbon nanotube/graphene composite film(50). The carbon nanotube/graphene composite film is curled and then twisted. The carbon nanotube film comprises a multiple carbon nanotubes parallel to a surface of the carbon nanotube film. USE - Method for making carbon nanotube composite wire(claimed). ADVANTAGE - The free-standing carbon nanotube film which sustain the weight of itself when it is hoisted by a portion without any significant damage to its structural integrity. A stacking the drawn carbon nanotube films which improve the mechanical strength of the carbon nanotube composite wire. Due to the carbon nanotubes in the flocculated carbon nanotube film is entangled with each other, the flocculated carbon nanotube film has excellent durability and is fashioned into desired shapes with a low risk to the integrity of the flocculated carbon nanotube film. A pressed carbon nanotube film is easy to bend to desired shapes without breaking. A carbon nanotube/graphene composite film is very straight and is twisted, thus a distance between adjacent carbon nanotubes decreases and mechanical strength of the carbon nanotube composite wire is improved. A distance between adjacent carbon nanotubes decreases and the van der Waals attractive force between adjacent carbon nanotubes increases which improve the mechanical strength of the carbon nanotube composite wire. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a method for making a carbon nanotube composite wire.
