Figure 21: a) Frequency sweep plots of coacervate sample at various salt concentrations taken at temperatures 20°C. These data fitted very well to power-law function (solid lines). See text for details. b) Frequency sweep plots at various temperatures 20, 25, 30 and 35°C are shown for a salt free coacervate material. Solid lines are power-law fitting to the data that yields the power-law exponent n and rigidity strength of the material, S. Reproduced with permission from American Chemical Society [12].
