  • Mixing and dispersion of nanotubes by gas or vapor expansion
    Patent number: 6908572
    Abstract: Novel methods and compositions for coating target surfaces with non-entangled multi-wall carbon nanotubes are disclosed. In one aspect, the methods and compositions of the invention comprise dispersion of non-entangled multi-wall carbon nanotubes in solvent, and application of the non-entangled multi-wall carbon nanotube/solvent mixture to a surface by spraying. In another aspect, the methods and compositions of the invention comprise dispersion of non-entangled multi-wall carbon nanotubes in solvent, and applying the nanotube/solvent mixture to a suitable matrix by spraying to form a surface coating which is substantially contiguous with the surface of the matrix. The compositions of the invention are substantially free of metal oxides and sulfur, and do not require harsh oxidative treatments.
