  • Patent number: 8197888
    Abstract: A dispersible nanocomposite comprising nanotubes associated with nanoplatelets. A method for creating an exfoliated nanotubes solution, aligning nanotubes and depositing them on a substrate or in matrix. In one embodiment, the method includes a nanocomposite of at least one nanotube electrostatically associated with at least one nanoplatelet. The nanoplatelets may be removed from the suspension by altering the ionic strength to create an exfoliated nanotube solution. The exfoliated nanotube solution for injection into microchannel templates and aligned deposition.
