NOVELTY - Method for manufacturing graphene-based materials involves (a) (i) positioning graphite into an inner chamber of a rotatable housing of a rod mill, (ii) rotating the housing of the rod-mill, and (iii) rod milling the graphite with the rods to produce a first portion of the graphene-based materials and milled graphite, or (b) performing the steps (i) and (ii), milling the graphite with rods to exfoliate graphite and produce milled graphite, and exposing the milled graphite to microwaves to thermally exfoliate the milled graphite and produce the graphene-based materials. The multiple elongate rigid rods are loosely positioned in the housing, the first portion of the graphene-based materials comprises 30 layers or less of graphene, and the milled graphite comprises more than 30 layers of graphene. The ratio of a total weight of the rods in the inner chamber to a total weight of the graphite in the inner chamber is 10-3000. USE - The method is useful for manufacturing graphene-based materials such as multi-layer graphene and graphene nano-platelets. ADVANTAGE - The method manufactures graphene-based materials in a scalable, cost-effective, and environmentally-friendly manner.
