The present invention provides graphene in which a polymer having a functional group capable of improving the dispersibility of graphene is bonded to the surface of the graphene. The present invention also provides a method for preparing the graphene described above.

Polymer grafted graphene and method for preparation thereof

The present invention relates to a method for preparing a functionalized graphene. The method for preparing a functionalized graphene according to the present invention can functionalize graphene by a simple method and does not use any other substance other than graphene and a salt containing a double bond, thereby enabling functionalization of graphene while exhibiting characteristics inherent to graphene.

Method for preparing functionalized graphene

The present disclosure relates to a graphene-nanomaterial complex, a flexible and stretchable complex including the same, and methods for manufacturing the complexes. A graphene-nanomaterial complex according to a first aspect of the present disclosure includes a plurality of graphenes and nanomaterials disposed between the graphenes, in which the graphenes are not disposed on the same plane to form a three-dimensional (3D) graphene structure, and the graphenes, the nanomaterials or both form an electrical network.
