▎ 摘  要

NOVELTY - Preparing readily dispersible graphene involves dispersing graphite oxide in deionized water by ultrasonic action to obtain graphene oxide dispersion liquid. The dispersion liquid is added with naphthalene-containing non-ionic surfactant and the solution is uniformly mixed. The mixed solution is then heated at 80-90 degrees C and added with reducing agent. The reaction mixture is then allowed to react for 9-12 hours. The obtained solution is cooled to room temperature and treated to easily obtain the dispersible graphene. USE - Method for preparing readily dispersible graphene (claimed). ADVANTAGE - The method enables to prepare readily dispersible graphene that has good stability, is able to reach very high concentrations and not influenced by changing pH environment.
