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.
Claims18
An applicator liquid comprising:
- a liquid medium containing a distribution of purified nanotubes;
- wherein said purified nanotubes remain separate from one another without precipitation or flocculation for a time sufficient to apply said applicator liquid to a surface;
- wherein said purified nanotubes are free of functionalization that deplete a electrons so that desired electrical properties of said purified nanotubes are maintained;
- wherein said liquid medium is an electronics grade non-halogen solvent;
- wherein said applicator liquid is free of surfactants and polymers;
- and
