METHOD OF SYNTHESIS OF CARBON NANOTUBES AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC C01B31/02 B82B3/00 B82Y40/00 

FIELD: nanotechnology.

SUBSTANCE: invention relates to the field of nanotechnology, and can be used to produce carbon nanostructures. The device for synthesis of carbon nanotubes comprises a chamber 1 filled with inert gas, in which the cylindrical carbonaceous cathode 2 and anode 3 are located, disposed coaxially, made with the ability of their movement relative to each other in the longitudinal direction. The anode 3 is divided into two sections: working 4 which is consumed in the process of synthesis, and discharging 5. The discharging section 5 of the anode 3 is made with a longitudinal cylindrical blind-ended channel 6. Heat removal from the central part of the discharging section 5 of the anode 3 is carried out using a copper cylindrical heat-removing element 7 with the radiator 8 fixed to the free end to the moment of complete evaporation of the working section of the anode 3. The carbon nanotubes are obtained in an arc discharge between the cathode 2 and the anode 3.

EFFECT: invention enables to increase the content of carbon nanotubes in the cathode deposit due to the expansion and regulation of the action area of temperatures characteristic for the first ionisation of carbon, on the free end of the anode.
