▎ 摘　　要

Metal matrix composites have been recognized as a feasible approach to obtain a new generation of biodegradable Zn-based material. Nevertheless, there is a great challenge in achieving good dispersion properties of the bioactive reinforcements within zinc matrix. A novel and facile approach, namely graphene oxide (GO)-assisted hetero-aggregation, were developed to achieve uniformly dispersed nanoceramics in the Zn matrix, by using very low-content (0.03 vol%) GO as a linker between the Zn matrix and reinforcement. lbe negatively-charged GO becomes a suitable "bridge" connected the positively-charged metallic powder and bioactive reinforcement by charge neutralization in polarity solvent. Three kinds of reinforcements, including M80, ZnO and CuO, were used to verify the feasibility of the abovementioned method. As-sintered 3CuO/Zn matrix composites, which possessed uniformly distributed reinforcement, uniaxial compressive strength of 301.2 MPa, failure strain over 40%, moderate corrosion rate of 0.063 mmy(-1) ceptable cytocompatibility and antibacterial property, should be a useful material for orthopedic applications.
