Table 1.
Parameter | Description |
---|---|
Storage Modulus max (G’max) | Maximum energy stored was reached. |
Loss modulus (G”) at G’max | Energy loss at G’max. |
Tan (δ) at G’max | Variable that describes behavior of the sample (solid- or liquid- like). |
Temperature at gelation point (tan (δ) =1) | Temperature measured at point where G’ and G” crossed over and the point at which tan (δ) =1. |
Peak temperature G’ | Temperature measured when the G’max is reached. |
aSlope 1 (S1) | Rate of change of G’ from the gelation point to G’max. |
aSlope 2 (S2) | Rate of change of G’ from G’max to the lowest point of the decreasing G’ (P1) |
aSlope 3 (S3) | Rate of change of G” from the gelation point to G”max. |
aSlope 4 (S4) | Rate of change of G” from G”max to the point before the G” levels off. |
a G’ trough | Lowest point after G’max. |
