Effect of disk radius r on the properties of disks for a constant sample composition. (a) Relative total rim area density At(r)/At(r1) and (b) vesiculation index Vf as a function of normalized disk radius r/r1 for dilution d = 80 and different salt concentrations cs (solid line: cs = 50 mM, dotted line: cs = 500 mM). Eqs. 5, 6, and 7 were solved simultaneously to obtain the composition, and then Eqs. 2, 4, 9, and 21 were used. Disks are assumed to be monodisperse. Parameters: ρ = 25 Å, aD = 200 Å2, αm = 10 kT, and Λ0 = 0.3 kT/Å.
