Depletion Interaction Due to Thin Colloidal Disks

Thin colloidal disks provide another example of an anisometrie eoUoidal particle as an efficient depletion agent. This problem was first eonsidered by Pieeh and Walz [61]. At the end of this seetion, where we compare spheres, rods and disks as depletion agents, we will see that the disk is intermediate in effieieney to induce depletion attraction between spheres and rods. Here we consider disks of diameter D and thickness L, see Rg. 2.30. Notiee that for the simplest ease, i.e., infinitely thin hard disks, the exeluded volume of the disks with respect to each other is nonzero and only in limit of the concentration going to zero will the disks behave thermodynamically ideal. We restrict ourselves to this limiting case.
