PROBLEM TO BE SOLVED: To reduce efficiently the thickness of NGF, and to remove impurities such as catalyst particles or polymer particles.SOLUTION: This method for producing nano-graphene includes a pretreatment step 2 of adding an organic solvent to nano-graphene fibers to remove a polymer compound adhering onto the fiber surface; a supercritical treatment step 3 of subjecting the organic solvent containing the nano-graphene fibers to a supercritical treatment to dismantle the nano-graphene fibers into graphene; and a post-treatment step 4 of removing impurities existing in the organic solvent containing the nano-graphene. |
