Abstract:
1. A method for processing carbon nanotubes comprising the steps of: preparing to-be-processed liquid with carbon nanotubes as raw material being suspended in a solvent; introducing a substantially continuous flow of the to-be-processed liquid through a light irradiation processing chamber; fragmenting the carbon nanotubes in the solvent in the length direction thereof by exposing the to-be-processed liquid as the to-be-processed liquid flows through the light irradiation processing chamber to pulse light having a predetermined wavelength; while the to-be-processed liquid is being stirred by a stirring means sending the to-be-processed liquid, after being exposed to the pulse light, to a recovery/circulation processing chamber adapted to receive the flow of the to-be-processed liquid; and circulating the to-be-processed liquid in a circulation flow path including the light irradiation processing chamber and the recovery/circulation processing chamber.
