発明の名称 (英語) Carbon nanotube-carbon nanohorn complex and method for producing the same
発明の概要(英語) (US7067096)
A novel carbon nanotube-carbon nanohorn complex produced by a method comprising step 1 for irradiating carbon nanotube placed in a liquid solvent with ultrasonic wave to disperse carbon nanotube into the liquid solvent, and step 2 for adding carbon nanohorn aggregate to the liquid solvent dispersed with carbon nanotube to thus remove the liquid solvent, whereby the surface of the carbon nanotube and the carbon nanohorn aggregate can be utilized more effectively and the availability can be enlarged.
特許請求の範囲(英語) [claim1]
1. A carbon nanotube-carbon nanohorn complex, which comprises a dispersion comprising carbon nanotubes and carbon nanohorns, said dispersion being aggregated to form a complex.
[claim2]
2. A method for producing a carbon nanotube-carbon nanohorn complex, comprising: a irradiating carbon nanotubes placed in a liquid solvent with ultrasonic waves to disperse the carbon nanotubes into the liquid solvent;
and
b adding carbon nanohorn aggregates to the liquid solvent in which the carbon nanotubes have been dispersed and then removing the liquid solvent.
[claim3]
3. The method for producing a carbon nanotube-carbon nanohorn complex according to claim 2, wherein the liquid solvent is an organic solvent.
[claim4]
4. The method for producing a carbon nanotube-carbon nanohorn complex according to claim 2, further comprising in a filtering the liquid solvent obtained by the step 1, in which the carbon nanotubes have been dispersed, and then putting a filtrate back to a liquid solvent.
[claim5]
5. The method for producing a carbon nanotube-carbon nanohorn complex according to claim 4, further comprising in b heating the carbon nanotubes filtered by step 1A in an oxygen atmosphere and then putting the carbon nanotubes back in a liquid solvent.
