Experimental Investigation of Rheological Properties of Coconut Oil-Graphene Oxide Nanocomposites

In this paper, the rheological properties of coconut oil (CO) and graphene oxide (GO) in coconut oil were experimentally investigated, focusing on the shear rate influence. The rheological characterization showed that the addition of graphene oxide nanoparticles led to an increase in viscosity with respect to the base fluid. Both CO and GO/CO suspension viscosities decreased at higher shear rate. To evaluate these findings, different viscosity-shear rate models (the Power law model and Cross model) were tested. The Cross model was successfully applied to fit the experimental results.
