▎ 摘 要
NOVELTY - Preparation of graphene powder comprises stirring liquid phase graphene at 200-300 revolutions/minute (rpm) for 25 minutes, adding precipitator, stirring for 1-2 minutes at 10-12 rpm, for 3-6 minutes at 5-7 rpm, and for 3-6 minutes at 18-22 rpm, standing for 4-8 hours, separating graphene sheets, evaporating solvent, and drying. USE - Method for preparing graphene powder (claimed).
