▎ 摘 要
NOVELTY - Preparation of graphene comprises mixing graphite oxide with deionized water to prepare 0.1-1 mg/ml graphite oxide solution, adding oxidized graphite solution into reaction container, applying alternating electric field on graphite oxide solution, and processing graphite oxide electrochemical reaction under environment change of the electric field generated. USE - Method of preparation of graphene (claimed). ADVANTAGE - The method is simple, has low cost, is safe, and has no pollution.
