title: Aqueous phase preparation of graphene with low defect density and adjustable layers.
abstract: Graphene sheets with an adjustable number of layers and a low defect density were prepared by exfoliation of microwave-assisted expanded graphite in the aqueous phase with the assistance of cetyltrimethylammonium bromide. The graphene sheets exhibit excellent film-formation ability, showing potential applications in optical and electrical device fields.
