▎ 摘　　要

Ethylene glycol (EG)-based hybrid nanofluids containing graphene oxide-silver nanosheets (GO-Ag) were simply prepared without using any surfactant. The graphene oxide-silver composites were characterized using X-ray diffraction analysis, transmission electron microscope, infrared and UV-visible spectroscopy. The stability of GO-Ag nanofluids was estimated by UV-visible spectroscopy. The GO-Ag/EG hybrid nanofluids has good stability without significant sedimentation for 60 days. A few thermophysical properties of GO-Ag/EG nanofluids with 0.1, 0.2 and 0.3 wt% nanosheets were analysed experimentally at different temperatures ranging from 20 to 50 degrees C.
