▎ 摘  要

NOVELTY - Graphene and graphene oxide production involves obtaining quantity of carbon rich materials in a solid state, mixing carbon rich material with a solvent, a surfactant, and an additive for forming a mixture, and then conducting the formed mixture into a microwave reactor. The microwave reactor is configured to provide microwave radiation to the mixture, where the microwave radiation is directed to the mixture in the microwave reactor. USE - Method for producing graphene and graphene oxide (claimed) 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. ADVANTAGE - The method produces the graphene and graphene oxide in a short time period of 300 seconds without involving any concentrated sulfuric acid, nitric acid or huge water quantities for purification. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic flowchart of the method for manufacturing graphene and graphene oxide through microwave irradiations by using carbon rich solid materials such as graphite, coal slags or asphalt. Obtaining graphite, coal slags, or asphalt (S10) Mixing solvent, surfactant and additive (S20) Conducting mixed suspension into properly designed microwave reactor (S30) Separating prepared grapheme and graphene oxide layers (S40)
