Certain spin-coatable liquids and application techniques are described, which can be used to form nanotube films or fabrics of controlled properties. A method of making an applicator liquid containing nanotubes for use in an electronics fabrication process includes characterizing an electronic fabrication process according to fabrication compatible solvents and allowable levels of metallic and particle impurities; providing nanotubes that satisfy the allowable impurities criteria for the electronics fabrication process; providing a solvent that meets the fabrication compatible solvents and allowable impurities criteria for the electronic fabrication process; and dispersing the nanotubes into the solvent at a concentration of at least one milligram of nanotubes per liter solvent to form an applicator liquid.

La présente invention se rapporte à des liquides pouvant former des revêtements par centrifugation ainsi qu'à des techniques d'application de ces liquides qui peuvent être utilisés pour former des films ou des toiles de nanotubes ayant des propriétés régulées. Un procédé de fabrication d'un liquide applicateur contenant des nanotubes conçus pour être utilisés dans un processus de fabrication de dispositifs électroniques consiste à caractériser un processus de fabrication électronique conformément à des solvants compatibles de fabrication et à des niveaux permis d'impuretés métalliques et particulaires; à se doter de nanotubes qui satisfont les critères d'impuretés permises pour le processus de fabrication des dispositifs électroniques; à utiliser un solvant qui satisfait les critères relatifs aux solvants compatibles de fabrication et aux impuretés permises pour le processus de fabrication électronique; et à disperser les nanotubes dans le solvant à une concentration d'au moins un milligramme de nanotube par litre de solvant pour former un liquide applicateur.
