Abstract
The present disclosure provides compositions and methods for dispersion of CNTs using a CNT solvent comprising an aromatic ring structure including at least one sulfonic acid functional group. Alternatively, the aromatic ring structure further includes at least a linear or branched alkyl chain. Examples of the carbon nanotube solvent includes dodecyl benzene sulfonic acid.
Claims26
A method comprising:
- combining dry carbon nanotubes with a carbon nanotube solvent, wherein the carbon nanotube solvent has an aromatic ring structure that comprises at least a sulfonic acid functional group;
- and
- mixing the carbon nanotubes and the carbon nanotube solvent to form a carbon nanotube suspension of the carbon nanotubes in the carbon nanotube solvent.
A composition comprising:
- a carbon nanotube solvent having an aromatic ring structure comprising at least a sulfonic acid functional group;
- and
- carbon nanotubes dispersed in the carbon nanotube solvent.
