Methods of dispersing carbon nanotubes

Patent ·
OSTI ID:1496632
; ; ;
A method is described for preparing carbon nanotube dispersions in organic solvents such as chloroform and methyl ethyl ketone. Structures resulting from organic dispersions are also disclosed. The dispersing agents used in this method comprise long chain hydrocarbons, halogen-substituted hydrocarbons, fluorocarbons, or a mixture of hydrocarbons, halogen-substituted hydrocarbons, and fluorocarbons; wherein the hydrocarbons, halogen-substituted hydrocarbons and fluorocarbons have from 6 to 40 carbons in a chain, at least one alkene or alkyne moiety, and at least one pendant carboxylic acid, phosphonic acid, and/or sulfonic acid group or an ester of these acids.
