Deformation simulations of three different colloidal networks with fixed average linker length (⟨M ⟩ = 5), including blends of short (M 1 = 2) and long (M 2 = 8, 10, or 12) linkers, address sensitivity of mechanical properties to linker-size distribution. Strikingly, the computed shear modulus and ultimate elongation of these networks were equivalent to those of the 5-mer gel. The ultimate tensile strengths of blended-linker gels were 20 -35% lower than that of 5-mer assembly, and in between those of the dimer and 8-mer gels, as expected.
