[Abstract]:Based on density functional theory and Yvon-Born-Green equation, the expression of particle depletion potential is obtained. Using density functional theory (DFT), the depletion potential and adsorption stability of colloidal particles in mixtures near single wall and in parallel slits are calculated. The results show that the volume fraction of different solvent components and particle size ratio have significant effects on the strength, force range and period of particle depletion potential. The adsorption stability of colloidal particles near single wall is closely related to the particle size ratio and volume fraction. In addition, for colloidal suspensions confined to parallel slits, the depletion potential well of colloidal particles also oscillates with particle size ratio and slit width.
