6 FAQs about [Storage modulus in gel]
Does rheology affect storage modulus in a gel-like state?
One can see the correlation between the rheology of typical yielding materials (presented by the flow curves) and the frequency independence of the storage modulus in the gel-like state (at low stresses) . Figure 5.
What is the storage modulus of cross-linked gels?
The storage modulus of cross-linked gels were determined via a DHR-1 rheometer (TA Instrument, USA), equipped with a parallel plate geometry (40 mm diameter and 1 mm gap) at 25 °C.
Do Gelma hydrogels change storage modulus?
GelMA hydrogels created from materials with low DS exhibited the greatest difference in storage modulus (G’) across the temperature sweep. For Low GelMA hydrogels photocured after incubation at 4°C and 37°C, the change in storage modulus (G’) was 21% and 81%, respectively. A similar trend was exhibited for both the Mid and High GelMA hydrogels.
