▎ 摘  要

NOVELTY - Preparing graphene, comprises drying and crushing the graphene oxide before the reduction of the graphene oxide to obtain graphene oxide with a mesh number corresponding to the specific surface area requirement of the graphene, where graphene is prepared by reducing graphene oxide. USE - The method is useful for preparing graphene. ADVANTAGE - The method crushes the oxidized dry graphene filter cake to obtain the filter cake precursor with smaller size, the precursor is fully heated in the thermal reduction process to improve the preparation area of the graphene powder, so that it can be better dispersed in the substrate in the downstream application field, exerting high performance advantages of the graphite. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) graphene preparation method; and (2) a product.
