Abstract
Disclosed is a composite carbon having a novel structure. This composite carbon has fibrous carbon which extends in the direction of the long axis, and multiple carbon nanotubes which are formed on the surface of the fibrous carbon and have a smaller diameter than the diameter of the fibrous carbon. The carbon nanotubes are formed as a group of multiple carbon nanotubes, with the lengthwise directions of each of the carbon nanotubes aligned in the same direction.
Claims20
A composite carbon, comprising:
- a fibrous carbon extending in a direction of a long axis thereof of the fibrous carbon;
- and
- multiple carbon nanotubes formed on the fibrous carbon and having a smaller diameter than a diameter of the fibrous carbon,
- wherein the carbon nanotubes are formed as a group of multiple carbon nanotubes with a lengthwise direction thereof of the multiple carbon nanotubes aligned in the same direction.
