Abstract
The present invention relates to a highly conductive carbon nanotube having bundle moieties with ultra low apparent density less than 0.01 g/cc. More specifically, this invention relates to a highly conductive carbon nanotube prepared by following preparation steps of i) preparing the sphere shape of metal catalyst by spray pyrolysis of catalytic metal precursor solution including low molecular weight polymer, ii) synthesizing carbon nanotube using carbon source and obtained metal catalyst according to thermal chemical vapor deposition method; and iii) obtaining a highly conductive carbon nanotube having bundle moieties with ultra-low bulk apparent density.
