  • Patent number: 12122675
    Abstract: The present invention discloses a method for efficiently dispersing carbon nanotubes. The method comprises mixing, in parts by mass, 1-30 parts of carbon nanotubes, 0.2-10 parts of functionalized carbon nanotubes and 400-1200 parts of a solvent, adjusting the pH of the resulting mixture to 5-9, and then ultrasonically dispersing the mixture to obtain a stably dispersed carbon nanotube dispersion; the functionalized carbon nanotube is one or more of a carboxylated carbon nanotube, a hydroxylated carbon nanotube, an aminated carbon nanotube, an acyl-chlorinated carbon nanotube, and a sulfonated carbon nanotube.
