Is the higher the storage modulus the better
Storage Modulus
The storage modulus determines the solid-like character of a polymer. When the storage modulus is high, the more difficult it is to break down the polymer, which makes it more difficult to force through a nozzle extruder. Therefore, the nozzle can become clogged and the polymer cannot pass through the opening. However, the polymer with the

Storage modulus (e'')
Storage modulus (e'') is a measure of a material''s ability to store elastic energy and is an important parameter in understanding the mechanical properties of polymers.

6 FAQs about [Is the higher the storage modulus the better ]
Why is loss modulus higher than storage modulus?
When the experiment is run at higher frequencies, the storage modulus is higher. The material appears to be stiffer. In contrast, the loss modulus is lower at those high frequencies; the material behaves much less like a viscous liquid. In particular, the sharp drop in loss modulus is related to the relaxation time of the material.
What is a storage modulus?
Join ResearchGate to ask questions, get input, and advance your work. The storage modulus gives information about the amount of structure present in a material. It represents the energy stored in the elastic structure of the sample.
Why does storage modulus increase with frequency?
At a very low frequency, the rate of shear is very low, hence for low frequency the capacity of retaining the original strength of media is high. As the frequency increases the rate of shear also increases, which also increases the amount of energy input to the polymer chains. Therefore storage modulus increases with frequency.
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.
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.
What does a high and low storage modulus mean?
A high storage modulus indicates that a material behaves more like an elastic solid, while a low storage modulus suggests more liquid-like behavior. The ratio of storage modulus to loss modulus can provide insight into the damping characteristics of a material.
