Abstract

The invention firstly discloses an oxidized graphene or graphene / inorganic particle core / shell material which is formed by electrostatic self-assembly, wherein inorganic particles are taken as the core of the material, oxidized graphene or graphene is taken as a shell layer, and the content of the oxidized graphene or the graphene is 0.1-2wt% of that of the inorganic particles. The invention alsodiscloses a preparation method of the oxidized graphene or graphene / inorganic particle core / shell material. Therefore, a new species is added for outer-coated inorganic powder materials and the application space of the inorganic particles is expanded; furthermore, the electrostatic self-assembly technology is further applied to the preparation of the oxidized graphene or graphene-inorganic powderhybrid material, and the method simultaneously has the characteristics of being mature and environmentally-friendly in process, being simple to operate, having no need of complex equipment, being easy for realization of large-scale production and the like.
