| 摘要 |
The present invention relates to a graphene-nanoparticle composite having a structure in which nanoparticles are crystallized at a high density in a carbon-based material, for example, graphene, and, more particularly, to a graphene-nanoparticle composite capable of remarkably improving physical properties such as contact characteristics between basal planes of graphene and conductivity since nanoparticles are included as a large amount of 20 to 50% by weight, based on 100% by weight of graphene, and a method of preparing the same. |

1. A graphene-nanoparticle composite in which primary nanoparticles crystallized in a surface of graphene have chemical bonds formed therein at a high density, wherein the primary nanoparticles are particles of at least one selected from the group consisting of Ni, Si, Ti, Cr, Mn, Fe, Co, Cu, Sn, In, Pt, Au, Mg, and a combination thereof, and are included at a content of 30 to 50% by weight, based on the total weight of the composite, and
wherein the crystallized primary nanoparticles have an average particle diameter of 50 to 200 nm. |
