THREE-DIMENSIONAL GRAPHENE STRUCTURE, AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a preparation method of a three-dimensional graphene structure, and a graphene structure prepared by the method, the method comprising the steps of: preparing a dispersion in which graphite oxide is dispersed; and controlling the degree of reduction of the dispersion so as to prepare a gel. It is possible to provide a three-dimensional graphene structure having a specific surface area, pore size or volume per unit mass or the like suitable for the field to be applied thereto.
