Stability Analysis – Capillary Forces between Pairs of Particles in the Foam Film
Parameters: s = 54 mN/m, a = 41deg, r = 3.5 m m. Formulae from Kralchevsky et al., J. Colloid Interface Sci., 151, 79 (1992); 155, 420 (1993)
The capillary forces arealways attractive and can be many orders of magnitude higher than kT.
To understand why we observe orderingonly with partially hydrophobic particles, the particle-meniscus interactions need also be considered.
