Abstract
A method for preparing modified graphene and a method for preparing a slurry containing the modified graphene are disclosed. The method for preparing a modified graphene comprises: putting a flake graphite powder, a silicon molecular modifier, water and a boric acid solution into a high pressure container, filling a liquid gas into the high pressure container, connecting the high pressure container to a solid gas preparation apparatus, to solidify the liquid gas and obtain a solid gas, putting the solid gas into a ultraviolet washing machine for ultraviolet high-energy radiation, exfoliating the graphene flake, continuously exposing to ultraviolet light for a period of time to form a modified graphene, continuously exposing the modified graphene under the ultraviolet light, and storing the modified graphene in vacuum as an intermediate.
