Abstract
Structure and properties of model colloidal suspensions in bulk solutions have been investigated using classical molecular dynamics simulations. The system consists of spherical particles (macroscopic colloids and microscopic counterions and/or coions) in a continuum solvent and is described using the primitive model. Variations in different properties with system parameters (colloid size, charge, concentration etc.) have been investigated. An effective one-component model [Adelman SA. J. Chem. Phys. 1976;64:724–731] of the multicomponent suspension is used to calculate the effective colloid–colloid potential, which develops an attractive minimum with increase in charge, size and concentration of colloid.
