NOVELTY - Preparing graphene nanosheets by micro friction wear comprises weighing artificial graphite and diamond micro powder in a volume ratio of 1:2, placing into the drum, adding artificial graphite and diamond micro-powder filler 2/3 of the drum volume, adjusting the rotating speed of the motor, running for 20-40 hours, taking out slurry powder in the roller, using de-ionized water for washing, washing and then filtering, washing and drying. USE - The method is useful for preparing graphene nanosheets by micro friction wear. ADVANTAGE - The method has no chemical oxidation-reduction method that uses a lot of strong acid and strong oxidants to bring pollution and no chemical vapor deposition method, is economical, environmentally friendly and simple.
