摘要：
An aligned carbon nanotube bulk aggregate of the invention is characterized by consisting of plural carbon nanotubes aligned in a predetermined direction and having a density of 0.2 to 1.5 g/cm3. The carbon nanotube bulk aggregate can be produced by a process of growing carbon nanotubes by chemical vapor deposition (CVD) in the presence of a metal catalyst which comprises growing carbon nanotubes in aligned state in a reaction atmosphere, soaking the obtained carbon nanotubes with a liquid, and then drying the resulting nanotubes. Thus, an aligned carbon nanotube bulk aggregate having a density of 0.2 to 1.5 g/cm3 can be obtained. The invention provides a high density and a high hardness which were not attained in the prior art, and a process for the production of the same.
