  • Patent number: 9922745
    Abstract: An aggregate of carbon nanotubes has an acid adsorption amount equal to or greater than 0.6 mass % and equal to or less than 12 mass %, which is obtained by subjecting a starting material composition containing carbon nanotubes to a two-stage wet oxidation treatment. A method of producing an aggregate of carbon nanotubes includes a primary oxidation treatment step, wherein a starting material composition containing carbon nanotubes is subjected to a wet oxidation treatment to give a primary treated aggregate of carbon nanotubes having a ratio (G/D ratio) of the height of G band to that of D band in Raman spectroscopic analysis at 532 nm wavelength equal to or greater than 30; and a secondary oxidation treatment step of performing a wet oxidation treatment under an oxidizing condition stronger than that of the primary oxidation treatment step.
