▎ 摘　　要

NOVELTY - A graphene material preparation method involves soaking an oxidized graphene product in a halogenation reagent such as hydroiodic, hydrobromic acid and thionyl chloride at (-5)-140 degrees C for 10seconds to 24 hours to form redox-type graphene material. USE - Method for preparing graphene material. ADVANTAGE - The method enables preparing graphene material with better conductivity, high efficiency, large-scale production and low cost, and allows keeping flexibility of a film product in easy to control manner and eliminating environmental pollution.
