▎ 摘　　要

NOVELTY - Method for producing graphene involves (a) forming mixed solution containing graphene oxide, dispersant, reducing agent and structural enhancer, (b) dripping mixed solution into coagulation solution to obtain graphene hydrogel, (c) performing freeze treatment and heat treatment on graphene hydrogel to obtain graphene. USE - Method for producing graphene. ADVANTAGE - The graphene has smaller particle diameter and lower density.
