Abstract
A carbon nano tube characterized by Bragg diffraction pattern peaks appearing at 2 theta (2θ)=26.5°, 44.5°, 51.8°. A carbon nano fiber is disclosed and characterized by Bragg diffraction pattern peaks appearing 2 theta (2θ)=44.5°, 51.8°. These carbon nano materials can be prepared in a solid phase by combustion and heating of the solid raw materials both with and without a tube control agent. The carbon nano tube growth process can include controlling the length of the tubes.
Claims40
A composition of matter comprising a carbon nano material which, when exposed to an X-Ray, exhibits a set of X-Ray diffraction peaks appearing at different angles (Θ) selected from the group consisting of:
- two theta (2Θ) angle=26.5°, 42.5°, and 44°;
- 2Θ=44.5°, and 51.8°;
- 2Θ=26.5°, 44.5°, and 51.8°;
