We report the production of high quality few-layer nanosheets of graphene from burning magnesium metal in dry ice. The prepared graphene sheets were characterized by nine methods, namely transmission electron microscopy, high resolution transmission emission electron microscopy, scanning electron microscopy, Raman spectroscopy, Fourier Transform-Infrared spectroscopy, energy-dispersive X-ray analysis, powder X-ray diffraction, Boehm , s titration, and N2adsorption–desorption technique. The rhe-ological properties of graphene–glycerol nanofluids were measured at different mass fractions (0.0025– 0.0200) and temperatures (20–60C). To the best of our knowledge, this is the first work on rheological properties of graphene–glycerol nanofluids. The experimental results showed that the viscosity of graph-ene–glycerol nanofluids increases with increasing the mass fraction and decreases with increasing tem-perature. Our results clearly showed a very strong shear thinning behavior of the graphene–glycerol nanofluids. A 401.49% enhancement in viscosity of glycerol was achieved by loading of 2% graphene nanosheets at shear rate 6.32 s1 and 20C.
