NOVELTY - A stable carbon nanotube fluid matrix comprises carbon nanotubes dispersed in a solvent mixture comprising a first solvent and a second solvent. The first solvent has boiling point of below 100° C, and the second solvent has a boiling point of above 100° C. The first solvent is a monohydric alcohol, and the second solvent is a diol. USE - Stable carbon nanotube fluid matrix used in coating or printing on substrate (claimed) e.g. plastic substrate. ADVANTAGE - The carbon nanotube fluid matrix has excellent stability with respect to various solvents by combining low boiling point solvents with high boiling point solvents. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: production of stable carbon nanotube fluid matrix, which involves providing a carbon nanotube composition comprising oxidized carbon nanotubes, and dispersing the carbon nanotube composition in the solvent mixture; method of coating or printing on substrate, which involves providing the concentrated carbon nanotube fluid matrix and printing or coating the concentrated carbon nanotube fluid matrix on a substrate; and a stable graphene fluid matrix, which comprises graphene dispersed in a solvent mixture comprising first solvent and second solvent.
