6 FAQs about [The greater the storage modulus the greater the rigidity]

What is storage modulus?

Storage modulus is defined as an index of a material's ability to rebound after deformation, reflecting its capacity to store elastic deformation energy. How useful is this definition? You might find these chapters and articles relevant to this topic. 2021, Bioinspired and Biomimetic Materials for Drug Delivery Georgia Kimbell, Mohammad A. Azad

Why does a wide polydispersity affect the storage modulus curve?

A wide polydispersity causes the storage modulus curve to be broad, since it involves measuring the sum of all storage moduli over the polydispersity range. Higher storage modulus improves material mechanical strength, but its ability to recover in an elastic manner might be more significant than the storage modulus value alone.

What happens if the storage modulus is high?

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 highest storage modulus will also be the most stable after printing.

Which hydrogel has the highest storage modulus and lowest loss modulus?

The hydrogel with the maximum concentration (90%) exhibits the highest storage modulus with respect to all other concentrations. It also shows the lowest loss modulus with respect to all concentration ranges. I am unable to explain it further, please suggest probable reasons.

What causes a decrease in storage modulus with increasing temperature?

A decrease in storage modulus with higher temperatures is most likely due to non-chemical/covalent cross-links weakening. For a more accurate diagnosis, it would be helpful to have more details on the type of hydrogel and cross-linker.

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.
