First claim
Opening claim text (preview).
The invention claimed is: 1. A metal-graphene composite comprising: a metal layer; and a graphene layer provided by being grown directly on one surface of the metal layer, wherein the graphene layer contains two or more graphene thin films and wherein the graphene thin films contain single-crystalline graphite grains each having a diameter of 10 μm or less and wherein the metal layer contains nickel (Ni) and wherein the graphene layer has a thickness of 100 nm or more and 300 nm or less and wherein the metal layer and the graphene layer have a thickness ratio of 1:0.005 to 1:0.05 and wherein the metal layer has a thickness of 10 μm or more and 50 μm or less and wherein the distance between the metal layer and the graphene thin film adjacent to the metal layer along a thickness direction is smaller than the distance between the graphene thin films contained in the graphene layer and wherein the metal-graphene composite has a Young's modulus of 160 GPa or more. 2. The metal-graphene composite of claim 1 , having a hardness of 2 GPa or more. 3. The metal-graphene composite of claim 1 , having a stiffness of 2.0×10 −6 N/m or more. 4. The metal-graphene composite of claim 1 , wherein the graphene thin films contain grains oriented in a vertical direction along a plane. 5. The metal-graphene composite of claim 1 , wherein the graphene layer comprises a D peak of 1,350 cm −1 which is not observed in the Raman spectrum. 6. The metal-graphene composite of claim 1 , wherein the metal layer further contains at least one of copper (Cu), cobalt (Co), iron (Fe), manganese (Mn), chromium (Cr), vanadium (V), titanium (Ti), platinum (Pt), gold (Au), aluminum (AI), magnesium (Mg), rhodium (Rh), tungsten (W), zirconium (Zr), and tantalum (Ta).
