<p>PURPOSE: A method for manufacturing graphene dispersed liquid and powder thereof are provided to prevent an organic solvent, which is harmful to environment, from being excessively used for an exfoliating step. CONSTITUTION: A method for manufacturing a graphene dispersed liquid comprises the steps of: obtaining expanded graphite by expanding an expandable graphite; obtaining quenched expanded graphite by quenching the expanded graphite; filtering the quenched expanded graphite; pulverizing and dispersing powder which is obtained from the filtering step; and treating a dispersed liquid with ultrasound waves.</p> |
