1. A mixture comprising tangled carbon nanotubes and discrete carbon nanotubes, wherein the average particle size of the carbon nanotubes in the mixture is from about 15 to about 85 microns and wherein the amount of tangled carbon nanotubes is from about 20 to about 80 percent based on the total weight of carbon nanotubes in the mixture; and at least one solvent; wherein the mixture further comprises side groups attached to the carbon nanotube exterior surface wherein the side groups comprise a molecular weight greater that 50 daltons.
