▎ 摘　　要

NOVELTY - A graphene product is produced by performing graphite mechanical exfoliation using specifically designed self-rotating propeller (2) and balls of material with defined dimensions, introducing into chamber with controlled environment and rotating graphite and balls to dry, performing exfoliation inside the sealed chamber (1) at temperature of 450-550 degrees C and speed of propeller of 900-1000 rpm, obtaining graphite material with surface area of 300-600 m2/g, extracting and filtering graphite material in continuous vacuum medium, and selecting pure and homogeneous graphite product. USE - Production of graphene product used for polymeric composite or biocomposites, ceramic or metallic component, thermoplastics or thermosets, silicones, textile material, electrodes, capacitors, conductive ink, and batteries or used in biomedicine or contaminated water and soil treatment (all claimed). ADVANTAGE - This method allows production of pure homogeneous graphene material with optimal properties, is environmentally friendly, and does not require the use of chemical agents, such as surfactants, organic intercalators, acids, or bases, or further treatments. Graphene product improves physical or chemical properties of composites. DETAILED DESCRIPTION - A graphene product is produced by performing graphite mechanical exfoliation using specifically designed self-rotating propeller (2) and balls of material with defined dimensions, introducing into chamber with controlled environment and rotating graphite and balls to dry, performing exfoliation inside the sealed chamber (1) at temperature of 450-550 degrees C and speed of propeller of 900-1000 rpm, obtaining graphite material with surface area of 300-600 m2/g, extracting and filtering graphite material in continuous vacuum medium, and selecting pure and homogeneous graphite product, having production of graphite material in amounts, qualities and times of less than or equal to 45 minutes per process, preferably 30 minutes. An INDEPENDENT CLAIM is included for graphene product which has surface area of 300-600 m2/g. DESCRIPTION OF DRAWING(S) - The drawing shows an isometric view of production of graphene product.
