Abstract
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.
Claims7
A carbon nanotube-carbon nanohorn complex, which comprises a dispersion comprising carbon nanotubes and carbon nanohorns, said dispersion being aggregated to form a complex.
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.
