摘要：This invention provides an innovative method to manufacture graphene layers

or quantities and graphene oxide layers or quantities from graphite, coal slags, asphalt,

and other carbon-rich sold materials in nature. The present invention uses controllable

microwave irradiation to heat the mixtures of base, graphite, or coal slags, or asphalt, or

their combinations with ionic liquids and surfactant plus environmentally friendly

oxidation agents. This invention can generate the said- products of graphene layers and

graphene oxides in a short time period of one second to 300 seconds. The present

invention does not involve any concentrated sulfuric acid, nitric acid, nor huge water

quantities needed for the purification, unlike the prior art. The as-produced graphene-

based materials can be used for preparing conductive films for touch screens, producing

graphene carbon fibers and three-dimensional porous graphene nanomaterials, and

preparing graphene -based other intelligent nanocomposites for super-light-weight

machines and vehicles.
