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 x 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.

La présente invention porte sur certains liquides applicables par centrifugation et sur certaines techniques d'application pouvant être utilisés pour former des films ou des tissus de nanotubes présentant certaines propriétés. Un liquide applicable par centrifugation pour formation d'un film de nanotubes comprend un milieu liquide contenant une teneur donnée en nanotubes purifiés, la teneur donnée étant suffisante pour qu'un tissu ou qu'un film de nanotubes de densité et d'uniformité présélectionnées soit formé, lequel liquide applicable par centrifugation comprend moins de 1 x 1018 atomes/cm3 d'impuretés métalliques. Le liquide applicable par centrifugation est substantiellement dépourvu d'impuretés particulaires dont le diamètre est supérieur à environ 500 nm.
