  • Patent number: 9424960
    Abstract: A method for producing an aggregated thread structure includes (a) a process of dispersing carbon nanotube to a first solvent, which is water or a mixed solvent containing organic solvent and water, with a surfactant, to create a dispersion and (b) a process of injecting the dispersion, in which carbon nanotube is dispersed, to a condensing liquid, which is a second solvent that differs from the first solvent, to thereby aggregate and spin carbon nanotube. The aggregated thread structure containing carbon nanotube has: a bulk density of 0.5 g/cm3 or more; a weight reduction rate up to 450° C. of 50% or less; a G/D ratio for resonance Raman scattering measurement of 10 or more; and an electric conductivity of 50 S/cm or more.
