▎ 摘　　要

NOVELTY - High-quality graphene is prepared by dispersing graphite powder in solution, creating turbulent flow, carrying out turbulence treatment for greater than or equal to 30 minutes, standing for 0.5-2 hours, taking upper layer, centrifuging with acceleration of 25-1600 g for 45-90 minutes, collecting supernatant, filtering, and distilling. USE - Method for preparing high-quality graphene (claimed). ADVANTAGE - The method has mild process conditions, low device investment, low raw material cost, high production safety, simple and easy operation, environment-friendly operation, high yield, and good reproducibility.
