NOVELTY - Forming carbon nanotube-polymer composites involves forming a mixture solution comprising several carbon nanotubes dispersed in a co-solvent comprising an organic solvent and a second solvent comprising a short chain fluorinated carboxylic acid, having a boiling point below 150 degrees C, less oxidizing than nitric acid, and soluble in both organic solvent and water; mixing a first polymer with the mixture solution to form a polymer comprising mixture; and removing co-solvent from the polymer comprising mixture to form a dispersed nanotube-polymer composite.    USE - For making carbon nanotube-polymer composites (claimed), useful in electromagnetic interference shielding, photovoltaic devices, and gas sensors.    ADVANTAGE - The composite has a higher electrical conductivity as compared to an electrical conductivity of the second polymer. The trifluoroacetic acid (TFA) provides an unusual combination of properties including a relatively low boiling point, excellent miscibility and solubility with a wide variety of both organic and inorganic compounds. The TFA and short chain fluorinated carboxylic acid materials provide highly dispersed carbon nanotubes (CNTs) in organic solvents and polymer matrices. As TFA is a highly volatile solvent, TFA evaporates, leaving very low trace levels in the nanocomposite. The resulting CNT nanocomposite materials thus have significantly improved electrical and mechanical properties as compared to available nanotube-polymer composites. The synergistic effect of carbon nanotubes and conducting polymers leads to a ternary nanocomposite material with beneficial electrical properties.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a carbon nanotube-polymer composite comprising a first polymer continuous phase, and several carbon nanotubes dispersed in the first polymer, where the carbon nanotubes in the composite consist essentially of non-functionalized nanotubes, and a short chain fluorinated carboxylic acid in a concentration from 0.1 parts per million to 1 parts per trillion.
