Rheological parameters of dynamic oscillational measurements.
| Parameter | Unit | Description |
|---|---|---|
| shear strain (γ) | % | Shear strain triggers the deformation of the rheological body. |
| Elastic or storage modulus (G′) | Pa | Storage modulus expresses the elastic feature of materials. |
| Viscous or loss modulus (G″) | Pa | Loss modulus expresses the viscous feature of materials. |
| frequency (f) | s−1 | Oscillation frequency of the upper geometry. |
| phase angle (δ) | ° (0–90°) | The difference in sinusoid oscillational curves, which is a measure of the deformation rate. |
| complex viscosity (η*) | Pa·s | The resistance against flow under oscillational experiments. |
| complex modulus (G*) | Pa | The normalized value of storage and loss moduli. |
| loss factor (tan δ) | - | G″/G′; the ratio of the loss (G″) and storage modulus (G′) is the loss tangent (loss factor). |
