Abstract

In the present study we are performing simulation of simple model of two patch colloidal particles undergoing reversible diffusion limited cluster aggregation using patchy Brownian cluster dynamics. In addition to the reversible aggregation of patches, the spheres are coupled with isotropic reversible aggregation through the Kern-Frenkel potential. We have investigated the effect of strength of bond (anisotropic and isotropic) interaction on self-assembly under different solvent qualities for various volume fractions. We define the strength of isotropic (anisotropic) temperature T_i (T_a).
