Response of Kappa gels (squares: 0.55 wt.%; circles: 0.75 wt.%; triangles 1.1 wt.%; diamonds: 1.5 wt.%; stars: 2 wt.%) to a sweep in the dynamic shear strain γ at 1 Hz and 20 °C: (a) storage modulus G′; (b) loss modulus G″. Inset: concentration dependence of the storage modulus G₀ measured in the linear regime; the line is a power law fit to the data, returning an exponent of n = 3.5 ± 0.4.
