Abstract
Official abstract text for this publication.
A carbon fiber film includes at least one carbon nanotube film including a number of carbon nanotubes joined end to end and extending along a same direction. Each of the number of carbon nanotubes is joined with a number of graphene sheets, and an angle is between each of the number of graphene sheets and the number of carbon nanotubes.

What is claimed is: 1 . A carbon fiber film comprising: at least one carbon nanotube film comprising a plurality of carbon nanotubes joined end to end and extending along a same direction; wherein each of the plurality of carbon nanotubes is joined with a plurality of graphene sheets, and an angle is defined between each of the plurality of graphene sheets and the plurality of carbon nanotubes. 2 . The carbon fiber film of claim 1 , wherein an outside wall of each of the plurality of carbon nanotubes is joined with the plurality of graphene sheets by a covalent bond. 3 . The carbon fiber film of claim 1 , wherein the plurality of carbon nanotubes is substantially parallel to a surface of the at least one carbon nanotube film. 4 . The carbon fiber film of claim 1 , wherein the angle is in a range from about 0 degrees to about 90 degrees. 5 . The carbon fiber film of claim 1 , wherein the angle is in a range from about 30 degrees to about 60 degrees. 6 . The carbon fiber film of claim 1 , wherein the angle is about 45 degrees. 7 . The carbon fiber film of claim 1 , wherein the plurality of graphene sheets is interval distribution on an outside wall of the plurality of carbon nanotubes. 8 . The carbon fiber film of claim 1 , wherein a length of the plurality of graphene sheets is greater than a diameter of the plurality of carbon nanotubes. 9 . The carbon fiber film of claim 1 , wherein a width of the plurality of graphene sheets is in a range from about 10 nanometers to about 20 nanometers. 10 . The carbon fiber film of claim 1 , wherein an extending length of each of the plurality of graphene sheets is 2.5 times-100 times as long as a diameter of each of the plurality of carbon nanotubes. 11 . A carbon fiber film comprising: a plurality of carbon fibers joined end to end and extending along a same direction, wherein each of the plurality of carbon fibers comprises a plurality of carbon nanotubes joined end to end and a plurality of graphene sheets joined with each of the plurality of carbon nanotubes, and an angle is defined between each of the plurality of graphene sheets and the plurality of carbon nanotubes. 12 . The carbon fiber film of claim 11 , wherein two adjacent carbon fibers side by side are spaced apart from each other. 13 . The carbon fiber film of claim 11 , wherein two adjacent carbon fibers are joined by van der Waals attractive force. 14 . The carbon fiber film of claim 11 , wherein the plurality of carbon nanotubes extends along a same direction. 15 . The carbon fiber film of claim 11 , wherein an extending length of each of the plurality of graphene sheets is 2.5 times-100 times as long as a diameter of each of the plurality of carbon nanotubes. 16 . The carbon fiber film of claim 11 , wherein the angle between each of the plurality of graphene sheets and the plurality of carbon nanotubes is in a range from about 0 degrees to about 90 degrees. 17 . The carbon fiber film of claim 11 , wherein the plurality of carbon fibers is parallel to a surface of the carbon fiber film. 18 .
