摘要
We show in the present letter that the organization of colloidal suspensions of very anisometric repulsive particles can be understood on the basis of simple geometrical considerations. Using a large set of rod-like and plate-like particles, we first evidence that the experimental inter-particle distances can be accurately predicted from geometrical constraints. We then show that the experimental static structure factors can be satisfactorily fitted using an effective Percus-Yevick structure factor. The fit parameters are then interpreted in terms of the co-excluded volumes of effective ghost particles, which further supports the geometrical representation previously developed.
