US Patent 7906208 - CNT composite fibers

Carbon nanotubes can be transformed into fibers and ribbons by a spinning process but such a process is made difficult when additives are included. This patent teaches a method in which colloidal particles are used to fabricate carbon nanotube ribbons and fibers more easily. Claim 1 reads:

1. Composite fibers comprising:

a polymer matrix, carbon nanotubes, and at least one of metal or metal oxide colloidal particles intimately and evenly mixed with the carbon nanotubes,

wherein the carbon nanotubes and the colloidal particles are aggregated to form ribbons or fibers and are evenly dispersed within the polymer matrix and throughout the whole body of the composite fibers.
