▎ 摘　　要

NOVELTY - The graphene-nanomaterial complex (100) includes nanomaterials (120) which are disposed between the graphenes, in which the graphenes are not disposed on the same plane to form a three-dimensional graphene structure (110), and the graphenes, the nanomaterials or both form an electrical network. The nanomaterials have one selected from the group consisting of a metal, a semiconducting material, a conductive polymer, a conductive oxide, a conductive nitride, a conductive carbide, and a carbon nanotube. USE - Graphene-nanomaterial complex used for electronic devices. ADVANTAGE - The graphene-nanomaterial complex has excellent dispersibility in a flexible and stretchable polymer and forms an electrical network to exhibit excellent electrical conductivity even though being present in a small amount in the polymer, and methods for manufacturing the complexes. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method of manufacturing a graphene-nanomaterial complex; and (2) a flexible and stretchable complex. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram illustrating a graphene-nanomaterial complex.
