METHOD FOR PREPARING GRAPHENE HYBRID MATERIALS, METHOD FOR REMOVING IMPURITIES OF GRAPHENE MATERIALS, AND GRAPHENE MATERIALS

摘要

The present invention maximizes the improvement of physical properties such as electrical conductivity by interplanar overlapping of materials by mixing two or more kinds of nano-plate materials including graphene materials, and by removing impurities of graphene materials, inherent properties of the graphene materials are adequately exhibited. The present invention provides a method for preparing graphene hybrid materials, which comprises the following steps: (a) imposing critical energy capable of vaporizing the impurities to the graphene material containing impurities to form pretreated graphene material; and (b) mixing the pretreated graphene material with nano-plate-shaped material having the thickness different from the thickness of the pretreated graphene material so that a material having the thinner thickness between the pretreated graphene material and the nano-plate-shaped material enters between a thicker material to widen the contact surface between materials.;COPYRIGHT KIPO 2017
