Abstract

See full text

Provided is an aggregate of carbon nanotubes satisfying (1) there is a 2θ peak at 24°±2° by X-ray powder diffraction analysis; (2) a height ratio (G/D ratio) of G band to D band by Raman spectroscopic analysis of wavelength 532 nm is 30 or more; and (3) a combustion peak temperature is from 550° C. to 700° C. The present invention provides an aggregate of carbon nanotubes excellent in dispersibility while high quality, giving a film, molded article, membrane or the like having excellent characteristics.
