The viscosity of Graphene nano-sheet suspensions (GNS)and its behavior withtemperature and concentration have been experimentally determined. A physicalmechanism for the enhanced viscosity over the base fluids has been proposed forthe poly-dispersed GNSs. Experimental data reveals that enhancement ofviscosity for GNSs lie in between that of Carbon Nanotube Suspensions (CNTSs)and nano Alumina suspensions (nAS) , indicating the hybrid mechanism ofpercolation (like CNTs) and Brownian motion assisted sheet dynamics (likeAlumina particles). Sheet dynamics and percolation, along with a proposedpercolation Network Dynamicity Factor; have been used to determine adimensionally consistent analytical model to accurately determine and explainthe viscosity of poly-dispersed GNSs. It has been hypothesized that the dynamicsheets behave qualitatively analogous to gas molecules. The model also providesinsight into the mechanisms of viscous behavior of different dilutenanoparticle suspensions. The model has been found to be in agreement with theGNS experimental data, and even for CNT and nano Alumina suspensions.
