Influence of graphene nano-platelets dispersion on the thermo-physical properties of sunflower oil

In this article, thermal stability, viscosity, density and surface tension of graphene nano-platelet dispersed in sunflower oil are experimentally determined by varying the concentration (0.1-1.1 wt.%) temperature (40-100?C). The SEM micrograph EDS spectra used to characterize graphene. Nanofluids prepared ultrasonication technique (two-step method) maximum stability about 280?C is achieved at 1.1 wt.% nanofluids. dynamic viscosity diminishes an exponential shape acquiescence with Arrhenius equation densities samples characteristic linear decrement estimated range. Density increase concentration, while a reverse trend observed raise. obtained nanofluid minimum 0.1 concentration.
