for simple Gaussian chains disregarding crosslinkers, with R e the single chain end-to-end distance. R 0 = lbN ν , is the endto-end distance of a free chain in solution, with b is the mean monomer-monomer distance, while l and ν are dimensionless quantities that depend on the chosen chain model. In our case, we have taken l = 1 and ν = 1/2 for ideal chains. Alternatively,
