Viscoelastic Scaling Regimes for Marginally Rigid Fractal Spring Networks

Non-Maxwellian viscoelastic stress relaxations in soft matter

“…[93][94][95] Other works have shown that the fractal nature of the percolating system remains in the gel structure well beyond the percolation threshold, and that these structures result in remnant signatures in the loss modulus 96 and the relaxation spectrum of the resulting gel. 97,98 In marginal spring networks, the underlying fractal structure has also been associated with a value of n that is substantially lower than 1/2 at high frequencies, 99 though a direct relation between d f and n is not yet clear in those systems. 100 Another important factor is viscous coupling and hydrodynamics.…”
