摘要：To address the issues of reduced graphene oxide(RGO) dispersion in co.per(Cu) matrix and interface bonding between RGO and Cu, an electrostatic adsorption method with interface transition phase design was employed to prepare the RGO/Cu based co.posites. Cu-Ti alloy powder was employed to improve the co.bination by forming carbides at the RGO-Cu interface. It was noted that the mechanical property of 0.3 wt.%RGO/Cu-Ti co.posite was increased by 60% co.pared with that of the matrix. Strengthening mechanism analysis suggested that the enhancement of the mechanical property was ascribed to the load transfer and seco.d phase strengthening which were from the improved dispersion of RGO and the in-situ formed titanium carbide phase.
