▎ 摘  要

NOVELTY - Preparing a highly dispersible graphene powder, involves adding graphene oxide to water, stirring and dispersing into an oxide graphite dispersion, ultrasonically stripping the graphite oxide dispersion for 20-30 minutes to obtain a graphene oxide dispersion, adding a reducing agent to the graphene oxide dispersion after ultrasonic stripping, stirring and heating, refluxing, and centrifuging to obtain partially reduced graphene. The partially reduced graphene is placed in a microwave drying apparatus and dried to obtain a highly dispersible graphene powder. USE - Preparation method of the high-dispersion graphene powder. ADVANTAGE - The preparation method of the high-dispersion graphene powder is simple and feasible, has less process flow, and is suitable for industrial production, and the prepared graphene has good dispersibility, low stacking degree and is not easy to agglomerate.
