Graphene reinforced copper matrix composites have become a research hotspot in copper matrix materials due to their excellent properties from graphene and copper, having promising applications in the fields such as electronics, energy and machinery. This paper provides a comprehensive overview of its research status, with a focus on various preparation methods,such as powder metallurgy, in-situ growth, electrochemical deposition,molecular level mixing, accumulative roll bonding and selective laser melting. The advantages and disadvantages of each method are analyzed,then, the optimization schemes proposed for addressing issues are delved such as the poor interface bonding between graphene and the copper substrate, the uneven dispersion of graphene and its tendency to agglomerate，the performance enhancement mechanism of graphene as a reinforcement relative to copper matrix composite materials is also elaborated. Finally, the development trends of graphene reinforced copper matrix composites in terms of process innovation, performance synergy optimization and expansion of application fields are prospected, aiming to provide references for their future in-depth research and practical application.
