Abstract

The rheological behaviour of poly(ethylene glycol) solutions (PEG) with different concentrations was evaluated using concentric cylinder rheometer. The shear rate-shear stress data emphasizes the emergence of the hysteresis loop but in the opposite concept of thixotropic fluids. The rheogram included the results of shear stress and apparent viscosity were obtained by applying the various step changing increments to the shear rate to reach appropriate value, followed by a stress decay at a steady shear rate after each upward step changes. Then, low shear rate was used by different decreasing levels, which showed reduction in the value shear stress. The steady shear was applied after each downward trend and showed a noticeable increment shear stress with time. The results of shear stress confirmed the ANTI-THIXOTROPIC behaviour of different solutions of PEG under all conditions. Increasing concentration of PEG fluids enhances the ANTI-THIXOTROPIC behaviour of the solutions.
