▎ 摘  要

NOVELTY - Preparing primary graphene by ultrasonic mixing comprises using at least two ultrasonic wave frequency components for ultrasonic mixing, taking graphite as a raw material, performing ultrasonic cavitation through different ultrasonic frequencies to produce raw material with different sizes, and subjecting the micro-bubble graphite raw material with bursting force to mechanical stripping to obtain primary graphene nano material. USE - The method is useful for preparing primary graphene by ultrasonic mixing (claimed). ADVANTAGE - The method: utilizes ultrasonic mixing process; obtains large stripping force; can greatly reduce the damage to the lamellar structure graphite material and crystal defect surface; and produces large sheets with high quality.
