In this work, a novel two-step method for high-yield preparation of FLG is developed by combining resonance ball milling and hydrothermal treatment. During the resonance ball milling process, the utilization of magnetic Fe 3 O 4 nanoparticles as a new "particle wedge" is beneficial to facilitate fragment and delamination of graphitic layers.

graphene by planetary ball milling. The raw material ratio is only 25mg, and the ball mill speed is only 100r/min. In Buzaglo's [32] study, the content of graphite was only 36mg. In summary, these two ball milling methods have low production efficiency and high cost, so they are not suit-able for road materials.
