On the basis of theoretical simulation of the corrugation of graphene and interaction between solvated graphene sheets, the paths of exfoliation of graphite into corrugated graphene sheets, fabrication into thin graphene films, assembly of the films into supercapacitors and characterization of the device performance will be taken to develop new techniques for scalable and cost-effective production of graphene-based bulk nanomaterial by nanoengineering inexpensive mineral graphite.
