▎ 摘　　要

NOVELTY - Preparing graphene by stripping method comprises (i) dispersing 0.12 g graphite powder in 60 ml methanesulfonic acid, sealing system to avoid contact with air, and ultrasonically dispersing mixture in low power ultrasonic apparatus for 2 hours, and (ii) centrifugating ultrasonic-finished solution at 3000 revolution for 90 minutes to remove un-peeled graphite particles, collecting upper solution i.e. graphene solution. USE - The method is useful for preparing graphene by stripping method (claimed). ADVANTAGE - The method is simple, has stripping rate, and graphene is dispersible.
