Thermogelling properties of purified poloxamer 407

A temperature sweep (10–40 °C) was conducted to record storage (G'') and loss modulus (G") of the poloxamer 407 solutions during gelation. T sol-gel was defined as the temperature at which the storage modulus (G'') is half way between the values of the storage modulus for the solution and the gel. Based on the preliminary strain sweep ...

5.4: Linear Viscoelasticity

The concept of "modulus" – the ratio of stress to strain – must be broadened to account for this more complicated behavior. Equation 5.4.22 can be solved for the stress σ(t) once the strain ϵ(t) is specified, or for the strain if the stress is specified. Two examples will illustrate this process: Example 5.4.2.

What is the effect of having a high storage modulus?

The storage modulus is the ''spring-like'' behavior of the material and the loss modulus is the ''dash pot-like'' behavior of the material (in reality, loss modulus is fairly complicated and usually depends on multiple material properties). A decreasing storage modulus means the strength of the spring-like portion is decreasing, simply put, it''s ...
