“…51 For both cases of 1LG-Cu-1O and 1LG-Cu-2O, the copper matrix with substitutional oxygen moving into interiors attracts the graphene layer moving closer to its side, suggesting an enhanced interaction between oxygen-mediated copper and graphene (Figure S16, panels a and b). To quantitatively characterize the interfacial mechanical properties, the binding energy between the graphene layer and copper substrate is calculated as E b = E G−M − (E G + E M ), 52 where E C−M , E G , and E M are energies of the hybrid systems, isolated graphene single layer and copper substrate, respectively. As shown in Table S1, the topfcc-1O and hcpfcc-2O cases each have the lowest binding energies of −1.34417 eV and −1.13559 eV.…”

Currently, seldom studies have paid close attention to the impact of the defects and oxygen-containing functional groups on the surface of the graphene for composite applications. In this work, two typical graphene materials, namely graphene nanosheets synthesized by an in situ catalytic reaction and reduced graphene oxide (RGO), were adopted to fabricate reinforced copper matrix composites by spark plasma sintering. A harmful transitional interfacial layer made up of Cu/CuOx/amorphous carbon/RGO, resulted from interfacial reaction between Cu and RGO, were observed in the RGO/Cu composite. In contrast, the in situ synthesized graphene with fewer defect and lower oxygen level can realize clean graphene−Cu interface with Cu−O− C bonding and thus lead to much improved interface bonding and superior yield strength and tensile ductility. These results imply that the in situ synthesized graphene is more favorable for achievement of robust interfacial bonding for enhancing the mechanical properties of the graphene-Cu composites.

“…However, these oxygen functional groups adversely affect the mechanical and physical properties of graphene. A study on the interaction between Cu and the pristine, atomic oxygen functionalized and boron-or nitrogendoped graphene by density functional theory calculation [98] revealed that the boron-doping effect is comparable or even better than the chemical bridging effect of oxygen. Moreover, it has been reported that boron-doped graphene exhibits higher electrical conductivity than pristine graphene [99] and its mechanical properties are similar to those of pristine graphene [100].…”

Recent research upon the incorporation of graphene into copper matrix composites is reviewed in detail. An extensive account is given of the large number of processing methods that can be employed to prepare copper/graphene composites along with a description of the microstructures that may be produced. Processing routes that have been employed are described including powder methods, electrochemical processing, chemical vapour deposition, layer-by-layer processing, liquid metal infiltration among a number of others. The mechanical properties of the composites are described in detail along with an account of the structural factors that control mechanical behaviour. The mechanics and mechanisms of deformation are discussed, and the effect of factors such as the graphene content and the type of graphene used, along with processing conditions for the fabrication of the composites, is described. The functional properties of copper/graphene composites are also reviewed including their electrical and thermal properties, and tribological and corrosion behaviour. In each case, the effect of the graphene type and content, and processing conditions are also described. Finally, possible future applications of copper/graphene composites are discussed.

“…Various fabrication techniques, including hot pressing sintering, spark plasma sintering (SPS), microwave sintering, etc. have been developed in the past many years to produce the CuMCs using graphene as a reinforcement owing to its unique structure and extraordinary physical/mechanical properties [4][5][6][7][8]. For example, Hu et al fabricated graphene reinforced Cu nanocomposites using a laser sintering method and achieved a 22% increase in Vickers hardness [9].…”
