Electrical Double Layer Interaction between Dissimilar Spherical Colloidal Particles and between a Sphere and a Plate:  Nonlinear Poisson−Boltzmann Theory

Abstract: Recently the double layer forces and interaction free energies between spherical colloidal particles, according to the Poisson-Boltzmann equation, have been accurately calculated by us and others. In this paper we conclude our investigations in this area by extending the calculation of double layer interactions to unequal spherical particles. We also consider the case of a sphere and a plate, a geometry relevant to atomic force microscope measurements when a colloidal particle is attached to the cantilever tip… Show more

“…In the framework of mean-field dilute-solution theory, the interaction force may be calculated by solving a nonlinear Poisson-Boltzmann (PB) equation for the electric potential, followed by integration of the electric stress and hydrostatic (osmotic) pressure over the particle surface [13]. This problem is nonlinear, and exhibits multiple scales in the common case where the Debye length is small compared to system dimensions.…”
