On the application of the modeling of the relaxation spectrum to the prediction of linear viscoelastic properties of surfactant systems

In this work, the linear viscoelastic properties of cetyltrimethylammonium tosilate-water system are predicted by the modeling of the relaxation spectrum. The modeled spectrum of relaxation times is of the “wedge-box” type where the “wedge” portion is located at the short-time scale of relaxation ti...

Description
Summary:In this work, the linear viscoelastic properties of cetyltrimethylammonium tosilate-water system are predicted by the modeling of the relaxation spectrum. The modeled spectrum of relaxation times is of the “wedge-box” type where the “wedge” portion is located at the short-time scale of relaxation times and the “box” part covers the long-time scale. The linear viscoelastic properties are calculated through the exact relationships with the suggested spectrum. Agreement between the calculated expressions and experimental data of the moduli and the stress relaxation function is found. Comparison is also made with predictions of the empirical expressions of the Cole-Cole and the Williams-Watts models.
