Structural properties of a two-dimensional model for partly quenched colloidal dispersions

We have investigated a two-dimensional model for a three-component mixture with a large difference in diameters of hard core particles mimicking two colloidal species and in diameter of solvent species. One of the colloidal species is assumed to be quenched in disordered configuration and forms an adsorbing medium. Another colloidal species together with the solvent component attains an equilibrium distribution in a microporous space. The system is studied by using replica Ornstein–Zernike integral equations. Our main focus is on the behavior of the potential of mean force between movable colloids dependent on matrix and solvent density.
