Abstract:

Particle aggregation in polydisperse colloids is studied theoretically. It is assumed that the aggregation follows phase transition scenario with the formation of dense uniform colloidal phases. Bidisperse model corresponding to the system of relatively ``large{''} and ``small{''} particles is considered. Van der Waals attraction between large particles and the action of relevant entropy forces due to the presence of ``depleted layers{''} of small particles are taken into account. The diagrams of equilibrium phase transitions of ``gas-liquid{''} and ``gas-solid{''} types occurring in the ensemble of large particles are constructed. The influence of size and concentration of small particles on the pattern and structure of phase diagrams is studied. It is shown that an increase in the concentration of small particles leads, on the one hand, to a rise of phase transition temperature and, on the other hand, to an increase in the threshold concentration of large particles.
