▎ 摘　　要

NOVELTY - Preparation of graphene comprises taking graphite and oxidizing to obtain graphite oxide; ultrasonically dispersing and stirring; placing into steam explosion pressure relief valve at 300-500 degrees C and 5-15 degrees C/minute for 2-10 hours; and washing and drying. USE - Method for preparing graphene (claimed) used for lithium electrode material, lubricating material, medicine, special catalytic coating material, and synthetic engine cylinder wear-resistant material. ADVANTAGE - The method is simple and environment-friendly and has short preparation time, low cost and high yield.
