Fitting of the storage moduli and loss moduli according to Eqns. (4), (9), (32), (16), (18), and (32). We have used fitting parameters for each individual experimental group as given in Table 1b. Note that there is no densification regime in the last group. One possible reason could be the failure or damage of the network under large compression. However, the data for strains smaller than 0.8 in the last group are consistent with the other data sets.
