METHOD OF CONTINUOUS MASS MANUFACTURING OF NANOFLAKE USING ELECTROCHEMICAL REACTION WITH ULTRASONIC WAVE IRRADIATION

摘要

PURPOSE: A method for continuous mass production of nanoflakes using an ultrasound-electrochemical method is provided to mass produce nanoflakes with enhanced dispersion capability and physical chemical performance at a low cost through a continuous complex processes of expansion/exfoliation/ ultrasound deintercalation using a electrochemical reaction and ultrasound. CONSTITUTION: A method for continuous mass production of nanoflakes using an ultrasound-electrochemical method comprises the following steps: stabilizing a surface by dipping a material with a laminating structure which is formed on an interlayer insertion and a counter electrode, and measuring voltage with an open circuit; and applying ultrasound with a frequency of 10-50 kHz and an output of 50-500 W. The method for continuous mass production of the nanoflakes comprises exfoliation, deintercalation, and dispersion in a single process. The laminating structured material is one selected from a group including graphite, carbon fiber, muscovitum, and highly oriented pyrolytic graphite(HOPG). The interlayer insertion is one selected from a group comprised of H2SO4, HNO3, and HCl. The nanoflakes have an average thickness of 0.04-50 nanometers and an average diameter of 500 nanometers-50 micrometers.
