Abstract
A Monte Carlo model for the coagulation of nanoparticles has been developed to predictthe terminal particle sizes and particle size distribution of nanoparticles. The coagulationmodel is divided into two stages. In the first stage, the model includes the phenomenon ofnucleation and growth via intermicellar exchange. The coagulation of nanoparticles is rapidduring this stage and occurs for a very brief period after the initial mixing of reactantscontained in the aqueous cores of reverse micelles. The repulsive force between particlesdetermines the fraction of collisions which lead to a successful coagulation event. Therefore,in the second stage, the efficiency of collisions between micelles containing particlesis modelled as a function of the diameters of the particles contained in them.The model predictions show a reasonable agreement with experimental data.
