Effect of Electrostatic Potential on the Depletion Interactions in Charged Colloidal Systems

Abstract

Abstract: In the colloidal systems confined by two parallel plates (one of which is weak charged),the author uses 4D hyper-spheres method to calculate the energy of the system and uses the acceptance ratio method to calculate the depletion interactions between a charged large-sphere and the plate.By analyzing and comparing with the results of the hard sphere system,it is found that electrostatic interactions can strengthen depletion interactions between the charged large-sphere and the confined plate.

Key words: colloid, hyper-sphere method, acceptance ratio method, depletion interaction, Monte Carlo simulations
