METHOD OF MANUFACTURING CARBON NANO TUBE WITH SEA URCHIN SHAPE, CONDUCTIVE FILLER-POLYMER COMPOSITE MATERIALS AND COMPOSITE SEPARATOR FOR FUEL CELL USING THE METAL-POLYMER COMPOSITE MATERIALS

摘要

PURPOSE: A method for manufacturing carbon nanotube with a sea urchin shape is provided to exhibit excellent dispersibility, conductivity and mechanical strength in a conductive filler-polymer composite material and to prepare the carbon nanotube with a sea urchin shape applicable to a conductive film or a separator for a fuel battery. CONSTITUTION: A method for manufacturing carbon nanotube with a sea urchin shape comprises the steps of: forming a catalyst layer made of a transition metal material on the surface of metal particles; injecting the metal particles in which the catalyst layer is formed into an electric furnace; injecting hydrocarbon gas inside the electric furnace, floating the metal particles, and synthesizing the carbon nanotube on the catalyst layer of the metal particle surface at the temperature of 600~900 C using the catalyst reaction.
