The storage modulus is a measure of how much energy must be put into the sample in order to distort it. The difference between the loading and unloading curves is called the loss modulus, E ". It measures energy lost during that cycling strain. Why would energy be lost in this experiment? In a polymer, it has to do chiefly with chain flow.
(8) for storage modulus, due to the superior loss modulus of samples compared to elastic modulus at the same frequency. These evidences establish that the viscos parts of polymers are stronger than the elastic ones in the prepared samples. Indeed, the loss modulus of samples predominates the storage modulus during frequency sweep.
Published online by Cambridge University Press: 07 April 2021 Chapter 2 introduces the statistical physics description of the rheology of concentrated colloidal suspensions at low Reynolds number. While the solvent is a Newtonian fluid, the suspension exhibits viscoelasticity and non-Newtonian rheology.

We display the comparison between experimental and theoretical results for some samples, but the predictions for all prepared samples properly fit to the experimental results. Fig. 1.
Additionally, “a” levels obtained by loss modulus are higher than those found by storage modulus indicating that the viscos parts of polymers in the samples are stronger than the elastic ones. The dynamic modulus improves by increments of frequency and “a” exponent.
