ELECTROCONDUCTIVE MATERIAL AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electroconductive material having a reduced electrical resistivity and a method for producing the same.SOLUTION: The electroconductive material comprises: carbon nano-tubes each having at least one open end; and iodine added to the carbon nano-tubes. The percentage of the mass of the iodine occupying in the total mass of the carbon nano-tubes and the iodine is 17% or more. The method for producing the electroconductive material comprises: a step of bringing the carbon nano-tubes each having at least one open end into contact with an electrolytic solution containing an iodine source; and a step of using the carbon nano-tubes brought into contact with the electrolytic solution for an action electrode and performing electrolytic oxidation.
