Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An aggregate of carbon nanotubes, wherein, at least 50 of 100 carbon nanotubes randomly selected from the aggregate of carbon nanotubes are double-walled carbon nanotubes when observed by a transmission microscope, a height ratio (G/D ratio) of G band to D band b Raman spectroscopic analysis of wavelength 532 nm of the aggregate of carbon nanotubes is 30 or more, and when a mixture of 10 mg of the aggregate of carbon nanotubes, 30 mg of sodium polystyre…
