摘要：
Graphene was synthesized using a Hummers-Offeman method and three types of metal sources (Pd, Fe and W) were introduced to prepare metal (oxide)-graphene composites. The prepared metal (oxide)-graphene composites were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive X-ray (EDX) analysis and Raman spectroscopy. Nanofluids containing metal (oxide)-graphene composites with a concentration of 1 mg/L were prepared using water as the base fluid. Among these three types of nanofluids containing metal (oxide)-graphene composites, Fe-graphene showed the best and most stable dispersion, highest thermal diffusivity and electrical conductivity.
