Single, multi-walled, functionalized and doped carbon nanotubes and composites thereof

摘要

The present invention relates to single walled and multi-walled carbon nanotubes (CNTs), functionalized CNTs and carbon nanotube composites with controlled properties, to a method for aerosol synthesis of single walled and multi-walled carbon nanotubes, functionalized CNTs and carbon nanotube composites with controlled properties from pre-made catalyst particles and a carbon source in the presence of reagents and additives, to functional, matrix and composite materials composed thereof and structures and devices fabricated from the same in continuous or batch CNT reactors. The present invention allows all or part of the processes of synthesis of CNTs, their purification, doping, functionalization, coating, mixing and deposition to be combined in one continuous procedure and in which the catalyst synthesis, the CNT synthesis, and their functionalization, doping, coating, mixing and deposition can be separately controlled.

1. A method for producing carbon nanotubes from a gas phase, comprising:
producing an aerosol of pre-made catalyst particles by physical vapor nucleation of catalyst material, the aerosol of pre-made catalyst particles being formed by nucleating supersaturated vapor; introducing said aerosol of pre-made catalyst particles into a reactor; introducing one or more carbon sources into the reactor; and reacting said pre-made catalyst particles and said one or more carbon sources in the reactor to produce carbon nanotubes.
