Very different types of straight and long multiwalled carbon nanotubes, ranging from semi-crystalline to highly crystalline, are obtained using a floating reactant method, by merely changing the flow rate of the carrier gas. Graphitization behaviors of these nanotubes are studied comparatively in terms of their microstructure and morphology, showing a large change in structure for the semi-crystalline nanotubes, but little change in the highly crystalline nanotubes with heat treatment. © 2001 American Institute of Physics.
