▎ 摘 要
NOVELTY - Preparing graphene by space-time synchronous ultrasonic ball milling involves adding graphite raw material and stripping reagent to ultrasonic ball milling device, ball milling in ultrasonic environment, and separating and drying the mixture to obtain graphite alkene powder. USE - Method for preparing graphene by space-time synchronous ultrasonic ball milling. ADVANTAGE - The method enables to prepare graphene by space-time synchronous ultrasonic ball milling which has high efficiency and high yield.
