A carbon nanotube sheet, comprising:
- a substrate;
- and
- a carbon nanotube layer derived from a carbon nanotube forest and wound on the substrate, wherein the carbon nanotube layer is composed of 5 or more layers.
An apparatus for fabricating a carbon nanotube sheet, comprising:
- a substrate;
- a rotating unit for rotating the substrate;
- and
- a deriving unit for deriving filamentary carbon nanotubes from a carbon nanotube forest,
- wherein carbon nanotubes derived by the deriving unit are rotated by the rotating unit.
A method of fabricating a carbon nanotube sheet, comprising the steps of:
- providing a carbon nanotube forest;
- deriving filamentary carbon nanotubes from the carbon nanotube forest by bringing the end of a metal pin as a deriving unit into the carbon nanotube forest to generate shear stress;
- and
- winding the derived filamentary carbon nanotubes on a substrate to form a carbon nanotube layer composed of 5 or more layers.
