▎ 摘  要

NOVELTY - Preparing graphene comprises (i) mixing halide salt particles and expanded graphite worm, and placing in a stirrer, (ii) sealing the stirrer, continuously stirring for 10-200 hours and allowing for complete contact of halide salt particle with the expanded graphite worm, (iii) removing halide salt, dissolving in water, filtering solid substance, washing the solid substance with clean water for multiple times, ultrasonic stripping, filtering, drying and purifying. USE - The method is useful for preparing graphene (claimed). ADVANTAGE - The method is simple and has low device requirement. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for preparing graphene, comprising a graphene inlet (1), a cylindrical roller (2) and a support frame (3). DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the device for preparing graphene. Graphene inlet (1) Cylindrical roller (2) Support frame (3)
