Spin-coatable liquid for formation of high purity nanotube films
First Claim
1. A spin-coatable liquid for formation of a nanotube film, comprising:
- a liquid medium containing a distribution of nanotubes, wherein the nanotubes remain separate from one another without precipitation or flocculation for a time sufficient to apply the spin-coatable liquid to a surface, and wherein the spin-coatable liquid is substantially free of particle impurities having a diameter of greater than about 500 nm.

Abstract
Certain spin-coatable liquids and application techniques are described, which can be used to form nanotube films or fabrics of controlled properties. A spin-coatable liquid for formation of a nanotube film includes a liquid medium containing a controlled concentration of purified nanotubes, wherein the controlled concentration is sufficient to form a nanotube fabric or film of preselected density and uniformity, and wherein the spin-coatable liquid comprises less than 1×1018 atoms/cm3 of metal impurities. The spin-coatable liquid is substantially free of particle impurities having a diameter of greater than about 500 nm.
