Title:
METHOD FOR MASS SYNTHESIS OF CARBON NANOTUBES AND CARBON NANOTUBES SYNTHESIZED THEREBY
Document Type and Number:
WIPO Patent Application WO/2020/141649
Kind Code:
A1
Abstract:
The present invention relates to a method for mass synthesis of carbon nanotubes and carbon nanotubes synthesized thereby and, more specifically, to a method for mass synthesis of carbon nanotubes and carbon nanotubes synthesized thereby, wherein the method enables not only the synthesis of a catalyst at a high rate through plasma generation without a separate reductant but also the continuous mass synthesis of high-purity carbon nanotubes. The technical essences of the present invention are a method for mass synthesis of carbon nanotubes and carbon nanotubes synthesized thereby, the method comprising: a first step of supplying a CNT growth material containing a carbon precursor; a second step of disposing a pair of metal wires in a solution mixed with a metal salt, and applying electric power to the metal wires to generate plasma to thereby synthesize a catalyst through a reduction of the metal salt into a metal atom; and a third step of thermally treating the CNT growth material and the catalyst to dissolve the carbon precursor in the catalyst, thereby continuously synthesizing carbon nanotubes while growing carbon nanotubes.
