Figure 7.

Large amplitude oscillatory shear tests (storage modulus G′, empty symbols; loss modulus G″, solid symbols, as a function of the applied strain) performed on gels formed in a Couette cell at 20 °C in 0.1 M KCl and with 1 wt.% carrageenan and characterized in Figure 5: (a) K2 extracted from M. stellatus and made of 68 mol.% of G4S-DA [69]; the solid line is computed from the exponential hardening model [102], whereas the red dotted line is computed from the filament-stretching-based model [95]; (b) blend of commercial K and I made of 70 wt.% of K.
