Abstract
Provided is a dispersion of carbon nanotubes having excellent dispersibility in an organic solvent. A dispersion according to an embodiment includes carbon nanotubes dispersed in an organic solvent with a polyimide containing an aromatic diamine compound represented by the following general formula (1) as a polymerization component. In formula (1), R1 to R8 are each selected from the group consisting of a hydrogen atom, a fluorine atom, a saturated aliphatic group, a saturated alicyclic group, and an aromatic group, and at least one of R1 to R8 is an aromatic group.
Claims8
A dispersion, wherein carbon nanotubes are dispersed in an organic solvent with a polyimide containing an aromatic diamine compound represented by the following general formula (1) as a polymerization component:
- wherein R1 to R8 are each independently selected from the group consisting of a hydrogen atom, a fluorine atom, a substituted or unsubstituted saturated aliphatic group, a substituted or unsubstituted saturated alicyclic group, and a substituted or unsubstituted aromatic group, and at least one of R1 to R8 is a substituted or unsubstituted aromatic group.
