A sequence of charged parallel flat plates immersed in a salt solution is used to model the swelling behavior of a polyelectrolyte. The solution of the nonlinear Poisson-Boltzmann equation gives rise to an analytical expression of the plate distance as a function of swelling pressure (p), plate char
