If storage modulus is greater than the loss modulus, then the material can be regarded as mainly elastic. Conversely, if loss modulus is greater than storage modulus, then the material is predominantly viscous (it will dissipate more energy than it can store, like a flowing liquid). Since any polymeric material will exhibit both storage and

The value of storage modulus was nearly one order of magnitude larger than that of loss modulus, indicating that elasticity was dominant. A stress of 1.5 Pa was the transition point between the linear and nonlinear viscoelastic regimes.

network or mesh size. The loss modulus displays a non-monotonic behavior. This leads to the situation that the storage modulus is larger than the loss modulus at some frequencies then there is a crossover where the loss modulus is larger. At the point where the loss exceeds the storage we observe yield in the material, i.e. the yield point.

6 FAQs about [The larger the storage modulus]

What happens if loss modulus is higher than storage modulus?

If it is higher than the loss modulus the material can be regarded as mainly elastic, i.e. the phase shift is below 45°. Higher storage modulus means higher energy storage capability of the material. Material flow recovery will be more than a smaller storage modulus value towards their original state after removing the applied force.

What is a storage modulus?

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.

What is the difference between tensile modulus and storage modulus?

Higher storage modulus means higher energy storage capability of the material. Material flow recovery will be more than a smaller storage modulus value towards their original state after removing the applied force. oung's modulus is referred to as tensile modulus, which is totally different material property other than the storage modulus.

What is elastic storage modulus?

Elastic storage modulus (E′) is the ratio of the elastic stress to strain, which indicates the ability of a material to store energy elastically. You might find these chapters and articles relevant to this topic. The storage modulus determines the solid-like character of a polymer.

Why is a complex modulus higher than a storage modulus?

Does a higher storage modulus mean less swelling?

Higher storage modulus means less swelling (assuming you're comparing hydrogels of the same type with different degrees of swelling). If you observe a decrease in the storage modulus with increasing temperature, it is most probably a result of non-chemical/covalent cross-links weakening.
