Figure 3

Osmotic pressure between between a negatively and positively surface (see Figure 2) as a function of the distance between both surfaces (H), calculated within the modified Langevin-Poisson-Boltzmann (MLPB) model for two values of the bulk salt concentration, n0/NA = 0.1 mol/L (dashed line) and n0/NA = 0.01 mol/L (full line). Other model parameters are : σ1 = −0.3 As/m2, σ2 = 0.3 As/m2, T = 298K, concentration of water, n0w/NA = 55 mol/L, and dipole moment of water, p0 = 3.1 Debye, where NA is the Avogadro number.
