摘要
FIELD: nanotechnologies.;SUBSTANCE: invention relates to nanotechnology. Carbon nanofibre with outer diameter 50-300 nanometres contains external shell from amorphous carbon and core from more than 1, but no more than 20 separate one-wall or double-walled carbon nanotubes. The method of obtaining of multiwall carbon nanotubes consists in annealing of the named carbon nanofibre at 2000-3200°C in absence of oxygen, for example, in the medium of inert gas, nitrogen or carbon dioxide.;EFFECT: obtained multiwall non-agglomerated carbon nanotubes have low defectiveness, improved mechanical properties, heat and electric conductivity.;5 cl, 5 dwg, 2 ex
