ABSTRACT

A method for fabricating graphene sheets or graphene particles includes (a) dispersing graphene oxide in an alcohol solution to prepare a graphene oxide dispersion solution, (b) reducing the graphene oxide dispersion solution under a supercritical condition to prepare graphene sheets or graphene particles, each of which is as a cluster of the graphene sheets, and (c) separating the graphene sheets or graphene particles, followed by washing and drying, and a method for fabricating a graphene film is configured to fabricate a graphene film in form of a thin film using the graphene sheets or graphene particles fabricated according to the method.
