Molecular Dynamics Simulation on Molecular Model for the Charged Colloidal Dispersion

Abstract

A molecular model is proposed for the charged colloidal dispersion. This molecular system consists of 256 particles with the charge 25e and 6400 particles with charge -e, where e is the unit charge. Molecular dynamics simulations are performed by NVT ensemble on a wide aria of (V,T) phase space, where T is the temperature and V is the volume of the system. The system has gas, liquid and solid phases and the charge 25e-particles have FCC structure in the liquid and solid phases.
