摘      要：In order to improve the interface wettability as well as the interfacial bonding between graphene and copper matrix,in this work,graphene nanoplates modified with nickel nanoparticles(Ni-GNPs)were synthesized using a one-step method based on spray-drying and chemical vapor ***,0.33 wt%Ni-GNPs were introduced into copper matrix composite by the molecular-level mixing method,leading to further enhancement of 90%in yield *** is attributed to the presence of Ni-GNPs,which provided high resistance to matrix against *** addition,with the modification of nickel at the interface,the wettability and interfacial bonding between graphene nanoplates and copper matrix were improved,which enhanced the load transfer ***,the microstructures and strengthening mechanisms were investigated and discus sed meanwhile.
