Formulation of the Molecular Theory

In Sections 2.2 and 2.3 we have anticipated some results from the molecular theory for polyelectrolyte-modified electrodes. We will briefly discuss here the formulation 

Equation 2.16 contains contributions from the translational entropy of the mobile species, the conformational entropy of polymer chains, the free energy associated with the different chemical equilibria in the system, the polymer-polymer and polymer-surface van der Waals (vdW) interaction energies, the electrostatic interaction energies and the repulsive interactions between all the different molecular species. The expressions for each of these terms are shown in Table 2.2, while the definition of the symbols is given in Appendix. Note that in Table 2.2, the densities.
