manufacturing mathod of CNT micro-ball, the CNT micro-ball thereby and electrode using the CNT micro-ball

摘要

The present invention relates to a method for manufacturing micro-balls using carbon nanotubes, and to a method for manufacturing an electrode using the micro-balls, having the technical aim of providing a method for manufacturing carbon nanotube micro-balls, carbon nanotube micro-balls manufactured by the method, and a method for manufacturing a transparent electrochemical electrode using the carbon nanotube micro-balls, wherein the method for manufacturing carbon nanotube micro-balls comprises: a first step of preparing a carbon nanotube solution by mixing carbon nanotubes with a solvent and a binder; a second step of preparing a liquid having dispersed carbon nanotubes by means of the ultrasonic dispersion of the carbon nanotube solution; and a third step of manufacturing carbon nanotube micro-balls by spray drying the liquid having dispersed carbon nanotubes. Thus, by spray drying the liquid having dispersed carbon nanotubes in order to manufacture the same into micro-balls, and coating the micro-balls on a top surface of a substrate to form an electrode, the degree of carbon nanotube dispersion can be improved, and electrode transparency and other electrochemical properties can be easily controlled.
