Claims12
A nanocarbon ink, comprising:
- nanocarbons, a solvent, and a polyoxyethylene alkyl ether represented by the following expression:
- CnH2n(OCH2CH2)mOH
- where, n=12 to 18 and m=20 to 100,
- wherein the nanocarbons are single-walled carbon nanotubes, and
- wherein an absorbance, which defines a concentration of the single-walled carbon nanotubes in the nanocarbon ink, at a wavelength of 310 nm when an optical path length is 10 mm is 0.2 or more.
