▎ 摘　　要

NOVELTY - Industrial electrolytic stripping preparation of graphene composite material comprises taking two 99.999% high-purity graphite rods as electrolytic cathode and anode; taking polymer or biomolecule as electrolyte; and under the condition of electrolytic additives, fast mixing, and constant direct voltage of 4-16V, electrolytic stripping high-purity graphite rod to obtain high-quality graphene composite material. The polymer or biomolecule is 1-ethoxy-3-methylimidazole sodium polystyrene benzene sulfonate, polyvinyl pyrrolidone, beta -cyclodextrin, chitosan, DNA, RNA, polypeptide, or protein. USE - Industrial electrolytic stripping preparation of graphene composite material (claimed) used for modifying electrode as biological sensor. ADVANTAGE - The method provides high-quality graphene composite material; needs only one direct-current potentiostat; has small investment, low cost, easily controlled reaction process, and no pollution; and is simple.
