Meanwhile, the conservative interparticle interactions can be approximated as colloidal interactions as dictated by the DLVO theory. Herein, we represent the total pair-wise conservative interactions as a combination of Van der Waals attraction and electrostatic repulsions. In the case of finitely sized spherical colloidal particles, the interparticle interaction can be calculated as an integrated Lennard-Jones interaction over multiple smaller spheres. The resulting colloid-colloid energy was derived in Everaers et al as :
