Abstract
According to example embodiments, a method includes dispersing carbon nanotubes in a mixed solution containing a solvent, the carbon nanotubes, and a dispersant, the carbon nanotubes including semiconducting carbon nanotubes, the dispersant comprising a polythiophene derivative including a thiophene ring and a hydrocarbon sidechain linked to the thiophene ring. The hydrocarbon sidechain includes an alkyl group containing a carbon number of 7 or greater. The hydrocarbon sidechain may be regioregularly arranged, and the semiconducting carbon nanotubes are selectively separated from the mixed solution. An electronic device includes semiconducting carbon nanotubes and the foregoing described polythiophene derivative.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
