Abstract

We investigated the effects of temporary network structures on linear and nonlinear viscoelasticity of polymer solutions by use of oscillatory shear (LAOS) flow. We tested two different types of polymer solutions: entanglement systems and ion complex systems. It was found that the entanglement network is difficult to show shear-thickening while network of ion complex gives rise to shear-thickening. The objectives of this paper are the test of strain-frequency superposition for various polymer solutions and to suggest a new method classifying complex fluids consisting temporary networks using LAOS data.
