To synthesize graphene economically and efficiently, as well as to improve the interface bonding between graphene and metal and to recede the aggregation issue of graphene, in this work, an easy and scalable bottom-up strategy for the mass production of metal nanoparticles modified graphene nanoplates (GNPs) was proposed. Cu nanoparticles modified GNPs (Cu-GNPs) and Ni nanoparticles modified GNPs (Ni-GNPs) were fabricated through this method, and then compounded with Al via ball milling technique. The as-obtained Ni-GNPs/Al composite showed simultaneously improved strength and toughness compared with unreinforced Al, while the Cu-GNPs/Al composite presented a greater strengthening effect. The microstructure and interface of the two composites were carefully characterized and investigated to reveal the difference. First principle study was also adopted to explore the binding energy of different interface structures. This study could provide new insights into the fabrication of GNPs and the control of interface in GNPs/Al composites.
