Abstract：Through the one-step thermal reaction of copper nitrate，thermal glycine and graphene oxide，the RGO/Cu
hybrid powder was successfully synthesized，and the RGO/Cu composites were prepared by discharge plasma sintering
RGO/Cu hybrid powder. The results show that Cu nanoparticles are uniformly distributed in the RGO lamellae. C-O-Cu
covalent bond is formed between RGO and Cu interface in RGO/Cu powder，and it remains in sintered RGO/Cu composites.
Compared with pure Cu，the yield strength and tensile strength of 0.6%RGO/Cu composite increase by 75.8%
and 47.7% respectively，while maintaining good elongation（29%）.
