Rheological properties of hydrogels based on ionic liquids

The storage modulus G′ characterizes the elastic and the loss modulus G″ the viscous part of the viscoelastic behavior. The values of G′ represent the stored energy, while G″ stands for the deformation energy that is lost by internal friction during shearing [ 35, 36 ].

Ratio of the loss modulus and storage modulus (tan δ )

The loss tangent (tan δ) was evaluated in addition to the dynamic moduli. Tan δ equals the ratio G"/G'' (Thorgeirsdóttir et al., 2006). A tan δ < 1 indicates that the sample has rigidity with ...

Dynamic modulus

Dynamic modulus (sometimes complex modulus ) is the ratio of stress to strain under vibratory conditions (calculated from data obtained from either free or forced vibration tests, in shear, compression, or elongation). It is a property of viscoelastic materials.

Storage Modulus and Loss Modulus vs. Frequency

Figure 4.13 (a) shows the results of the storage and loss modulus vs. frequency at temperature 25°C. The G'' increases from 0.018 MPa to 0.77 MPa, and also, the G" increases from 0.0187 MPa to 0.22 MPa as the frequency increases from 0.01 Hz to 100 Hz.
