TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The fluid further comprises water. The discrete carbon nanotubes comprise oxygen moieties at 0.5-8 wt.% of the carbon nanotube. The majority of discrete carbon nanotubes are open ended. The residual catalyst from making the carbon nanotubes is less than 2 wt.% of the carbon nanotubes. The fluid further comprises at least one other species comprising carbonaceous materials.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The surfactant is at least partially bound to the discrete carbon nanotube. The surfactant is present at greater than 0.2 to less than 3 weight fraction relative to the weight of carbon nanotubes. The surfactant comprises at least 0.5 wt.% relative to the weight of fluid of polymer soluble in the fluid. The polymer further comprises an oxygen and/or sulfur moiety. The surfactant is polyvinyl alcohol, polyvinyl alcohol copolymer, where at least 50 mole% of the vinyl units comprise hydroxy groups, or polystyrene sulfonate. The polymer has molecular weight of less than 200 kDa. The surfactant is bio compatible or amorphous. EXAMPLE - 15 g Dry Molecular rebar (RTM: Carbon nanotube, with average length of 900 nm, average diameter of 13 nm, with 1.8 wt.% oxidation and 1.6 wt.% of residual content) (MR) was placed in a 500 ml beaker. 3.375 g Polystyrene sulfonate (PSS) was added as 22.5 ml of a 15% stock solution and mixed with a 100 ml water using an overhead stirrer rotating at 800 rpm. This provides 1:0.225 pts.wt of MR and PSS. The mixture was adjusted to pH 7 with 1M sodium hydroxide and the overhead mixer was slowed to 300 rpm. The volume of the fluid was then adjusted to a total of 250 ml using water to produce a final mixture of 6 wt.% MR and 1.35 wt.% of PSS at pH 7. The fluid was then sonicated using a sonication probe set at a power setting of 40W for 1 hour while maintaining a temperature below 35 degrees C. The fluid was inspected using a light microscope at 45x magnification and shows a uniform dispersion of carbon nanotubes, after three weeks at 25 degrees C. The dispersion remains uniform. The fluid had the viscosity of cream which was 0.1 poise.
