Title
(EN) CONTINUOUS MANUFACTURING METHOD OF CARBON NANOTUBES
(KO) 연속식 탄소나노튜브의 제조 방법
Abstract
(EN) The present invention relates to a continuous manufacturing method of carbon nanotubes, wherein the method comprises: a mixture manufacturing step of mixing and stirring a solvent, a metal salt, a surfactant, a reducing agent and a function improving agent to manufacture an emulsion mixture; a gaseous mixture forming step of mixing the emulsion mixture with a carrier gas to form a gaseous mixture; and a reaction step of introducing the gaseous mixture into a heated reactor to form carbon nanotubes, and thus the diameter of carbon nanotubes can be uniformly controlled, and the yield of carbon nanotubes can be increased.
