Abstract
(EN)
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.

La présente invention concerne une méthode de synthèse en masse de nanotubes de carbone et des nanotubes de carbone ainsi synthétisés, la méthode permettant non seulement la synthèse d'un catalyseur à un débit élevé par génération de plasma sans réducteur séparé mais également la synthèse en masse continue de nanotubes de carbone de haute pureté. La présente invention concerne essentiellement, sur le plan technique, une méthode de synthèse en masse de nanotubes de carbone et des nanotubes de carbone (NTC) ainsi synthétisés, la méthode comprenant : une première étape consistant à fournir un matériau de croissance de NTC contenant un précurseur de carbone; une seconde étape consistant à disposer une paire de fils métalliques dans une solution mélangée avec un sel métallique, et appliquer de l'énergie électrique aux fils métalliques pour générer un plasma pour ainsi synthétiser un catalyseur par une réduction du sel métallique en un atome métallique; et une troisième étape consistant à traiter thermiquement le matériau de croissance de NTC et le catalyseur pour dissoudre le précurseur de carbone dans le catalyseur, ce qui permet de synthétiser en continu des nanotubes de carbone tout en faisant croître des nanotubes de carbone.
