Abstract
High purity multiwall carbon nanotubes (MWCNTs) were synthesized by a continuous mass production apparatus using a catalyst vapor deposition method. The continuous mass production apparatus consisted of a moving heater and a gas decomposer, and this continuous mass production apparatus of carbon nanotubes shows the possibility of industrial scale production of carbon nanotubes. The MWNTs have lengths of several micrometres and diameters in the range of 20 to 60 nm with over 90% purity, a straight and smooth structure. Their Raman spectrum shows two strong peaks at 1569 and 1334 cm−1.

Keywords: Mutiwall carbon nanotube, CNT mass production system, CNT continuous production system.
