Cup-stacked Carbon Nanotubes and Method of Preparing Same

摘要

PURPOSE: A cup-type carbon nano-tube and a method for manufacturing the same are provided to obtain the superior dispersibility with respect to aqueous solution, organic-based solution, or polymer-based solution by dispersing edge carbon on the inner surface of the carbon nano-tube. CONSTITUTION: A cut-type carbon nano-tube is synthesized by the reaction of the mixture of gaseous carbon precursor, ambient gas, and catalytic gas. The mixture is reacted in a reactor(210). A carbon layer outer wall is formed on the axial direction of the carbon nano-tube. The carbon layer outer wall is inclined into a pre-set angle. Edge carbon is dispersed on the inner surface of the carbon nano-tube. The inner side of the carbon nano-tube is hollow.
