▎ 摘　　要

NOVELTY - Synthesizing a functionalized graphene sheet comprises: exposing first and second adjacent graphene sheets to a first species under a set of conditions, which facilitates electrochemical intercalation of the first species between the first and second graphene sheets, to produce an activated graphene material; and exposing the activated graphene material to a second species under a set of conditions, which facilitates electrochemical intercalation of second species between the first and second adjacent graphene sheets of the activated graphene material. USE - The method is useful for synthesizing a functionalized graphene sheet (claimed). ADVANTAGE - The method is capable of simply, rapidly and economically synthesizing the functionalized graphene sheet with high yield, improved electronic properties and without need for the harsh oxidation and/or reduction of graphene. DETAILED DESCRIPTION - Synthesizing a functionalized graphene sheet comprises: exposing first and second adjacent graphene sheets to a first species under a set of conditions, which facilitates electrochemical intercalation of the first species between the first and second graphene sheets, to produce an activated graphene material; and exposing the activated graphene material to a second species under a set of conditions, which facilitates electrochemical intercalation of second species between the first and second adjacent graphene sheets of the activated graphene material, where the first species, intercalated between the first and second adjacent graphene sheets, facilitates intercalation of the second species between the first and second adjacent graphene sheets.
