Microwave extraction of graphene from carbon fibers

A microwave method for extracting graphene and few-graphene stacks from turbostratic carbon fibers is reported. Microwave radiation is used as an additional energy source in the unzipping of tubular carbon structures in conjunction with hydrogen peroxide, a mild oxidizing agent. This minimizes the problems associated with excessive oxidation and considerably shortens the overall processing time.
