From Potentials to Volume Fractions

At this stage we assume that at each coordinate r = (z, r) we know the volume fractions of all molecular species, which we genetically will denote as pA(f) = A(f)/f (f). where n-A is the number of segments of type A. These distributions involve all allowed conformations of the molecular species in the system (see next section). Table 5.1 lists the properties of these molecules. Water is the first component, t= 1, and each molecule occupies five lattice sites (molecular volume N=vjb = 5). In the case shown in the table, the positive (t = 3) and the negative (t = 4) ions have the same 

The interaction term (second term in Equation 5.6) is normalized in such a way that the potential vanishes in the bulk of the water-phase. 

The third term of Equation 5.6 accounts for the electrostatic interactions, which we implemented on the level of the Poisson-Boltzmann theory for electrified interfaces. The electrostatic potential t(r) is found from the Poisson equation which for the
