Abstract
A method for manufacturing an inorganic-nano structure composite, a method for manufacturing a cabon nanotube composite by using the same, and a carbon nanotube composite manufactured by the same are provided. The method for manufacturing the inorganic-nano structure composite comprises a step of doping pentavalent elements on the nanostructure; and a step of growing the inorganic material from the doping points of the pentavalent elements by dipping the nanostructure on which the pentavalent elements are doped into a precursor solution of the inorganic material, and according to the present invention the pentavalent elements such as nitrogen are doped on the nanostructure and is utilized as the crystallization point of the inorganic material, instead of forming the separate coating layer to the organic-based nanostructure, or binding the binding group to the surface.
