Single-walled carbon nanotube orientation aggregate , bulk -like single -walled carbon nanotube orientation aggregate , powder -like single -walled carbon nanotube orientation aggregate

摘要

An aligned single-walled CNT aggregate which can readily be produced, whose specific surface are is high, whose individual carbon nanotubes (CNT) are aligned orderly, and whose bulk density is low whereby exhibiting a processability is provided. An aligned single-walled CNT aggregate should comprise a base material, fine particles of catalyst with a number density of 1 × 10 10 to 5 × 10 13 N/cm 2 disposed on this base material, and a plurality of single-walled CNTs which are grown from the fine particles of the catalyst, wherein the plurality of single-walled CNTs have a specific surface area of 600 m 2 /g to 2600 m 2 /g, and a weight density from 0.002 g/cm 3 to 0.2 g/cm 3 , and the alignment degree is defined by specific conditions.
