Using commercial expandable graphite as raw material, a novel, low-cost, and feasible method for the fabrication of graphene has been developed by Rong-Jie Yang, Feng-Lei Huang and co-workers (article no. ) based on the liquid exfoliation method. Volume-restricted expansion of the expandable graphite is demonstrated to be a convenient method to prepare a suitable carbon precursor to be exfoliated. The analysis results confirmed the prepared graphene to be a kind of multi-layer graphene with high-crystallinity and excellent thermal stability.
