Abstract
The rheological properties of graphite oxide (GO) of high concentrations were studied, which is important for pumping and translating design. Steady test indicated GO displayed shear thinning behaviors at low shear rates. The viscosity and particle increased quickly above certain shear rates. The Herschel–Bulkley model represented flow behavior accurately. Correlations between solid content, temperature, and viscosity were expressed by an exponential equation and a modified Arrhenius type equation, respectively. The dynamic test indicated viscoelasticity of GO decreased remarkably at lower concentrations. Under shearing, network structure of GO broke down gradually, and viscosity decreased with time, causing flow acceleration.
