Aligned single-walled carbon nanotube aggregate, bulk aligned single-walled carbon nanotube aggregate, and powdered aligned single-walled carbon nanotube aggregate

摘要

This invention provides an aligned single-walled CNT aggregate comprising a substrate, fine particles of iron catalyst with a density of 1×10¹¹ to 1×10¹⁴/cm² disposed on an alumina co-catalyst above the substrate, and a plurality of single-walled CNTs grown from the fine particles of the iron catalyst, in which the plurality of single-walled CNTs have a specific surface area of 600 m²/g to 2600 m²/g, and a weight density from 0.002 g/cm³ to 0.2 g/cm³, and the alignment degree which satisfies a few of specific conditions. This invention also provides a bulk aligned single-walled carbon nanotube aggregate and a powdered aligned single-walled carbon nanotube aggregate.
