Aqueous dispersions and methods of making same

摘要

The present invention, in one aspect, provides aqueous dispersions of carbon nanotubes. In some embodiments such aqueous dispersions can be applied to fiber glass strands to impart one or more electrically conductive properties to the fiber glass strands.

主权项

1. An aqueous carbon nanotube dispersion comprising:
carbon nanotube particles present in an amount of at least about 1 weight percent on a total solids basis, wherein the carbon nanotube particles comprise a plurality of carbon nanotubes and have a mean particle size that ranges from about 250 nm to about 2 μm; and a polymeric carrier, the polymeric carrier comprising an aqueous dispersion of one or more polymeric species; wherein the aqueous carbon nanotube dispersion has a viscosity of 1100 to 4500 cP at 5 RPM and 25° C.
