METHOD FOR PRODUCING CARBON NANOTUBES, METHOD FOR PRODUCING LIQUID DISPERSION THEREOF AND OPTICAL PRODUCT

摘要

A method for producing dispersible carbon nanotubes of the invention comprises subjecting single-walled carbon nanotubes to UV treatment in the presence of ozone such that carboxyl groups are introduced into the single-walled carbon nanotubes and that the single-walled carbon nanotubes are fragmented. A carbon nanotubes obtained by the method has a good dispersibility.
