Abstract

The present invention relates to a method for preparing graphene by using a novel block copolymer. The exfoliation efficiency of graphene can be increased and the dispersion stability thereof can be increased by using the block copolymer of the present invention during high-pressure homogenization mediated by graphene, which is hydrophobic, and a solvent of a feed solution, which is hydrophilic.
