Abstract:
1. A method of producing a carbon nanotube dispersion, comprising: providing a quantity of non-functionalized single-walled carbon nanotubes having a wet condition; combining the non-functionalized single-walled carbon nanotubes with water to form a nanotube-water mixture comprising 2% (by weight) or greater of non-functionalized single-walled carbon nanotubes wherein the nanotube-water mixture lacks additives or external chemical agents; and sonicating the nanotube-water mixture at a high frequency until the sonicated mixture comprises a mixture of the nanotubes and the water which comprises the carbon nanotube dispersion, wherein the carbon nanotube dispersion has a viscosity of at least 0.111 Pa.sec at a shear rate of ≦3657 s
