First Claim
Patent Images
1. An applicator liquid comprising:
- one or more carbon nanotubes andan electronics-grade liquid medium comprising water,wherein the carbon nanotubes are distributed in the liquid medium without substantial precipitation, flocculation or other macroscopic interaction and can remain separated for about at least one week,wherein the nanotubes are at a concentration of greater than or equal to 10 mg/L,wherein the nanotubes are pretreated to reduce a level of metal impurities to less than about 1×
1018 atoms/cm3,wherein the applicator liquid is substantially free of polymers and surfactants, andwherein the applicator liquid is substantially free of particulates having a diameter greater than about 500 nm.

Abstract
Certain applicator liquids and method of making the applicator liquids are described. The applicator liquids can be used to form nanotube films or fabrics of controlled properties. An applicator liquid for preparation of a nanotube film or fabric includes a controlled concentration of nanotubes dispersed in a liquid medium containing water. The controlled concentration is sufficient to form a nanotube fabric or film of preselected density and uniformity.
