METHOD FOR SEPARATING METALLIC CARBON NANOTUBES BY USING MICROWAVE

摘要

PURPOSE: A method for isolating metallic carbon nano tube through microwave is provided to remove semiconductive carbon nano tube. CONSTITUTION: A method for isolating metallic carbon nano tube comprises: a step of irradiating microwave to carbon nano tube mixture containing metallic carbon nano tube and semiconductive carbon tube to remove semiconductive carbon nano tube; a step of adding acid solution; and a step of irradiating microwave to remove impurities. The carbon nano tube is selected from a group comprising single walled-carbon nano tube, double-walled carbon nano tube and multi-walled carbon nano tube.
