Abstract
Provided is an aggregate of carbon nanotubes wherein a mixture of 10 mg of aggregate of carbon nanotubes, 30 mg of sodium polystyrene sulfonate and 10 mL of water is subjected to ultrasonic homogenizer treatment, subsequently subjected to centrifugal treatment at 20000 G, then 9 mL of supernatant is sampled, and the content of aggregate of carbon nanotubes in the supernatant is 0.6 mg/mL or more. The aggregate of carbon nanotubes of the present invention can provide a dispersion of an aggregate of carbon nanotubes having a high concentration through very good dispersibility.
