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 are always attractive and can be many orders of magnitude higher than kT.

To understand why we observe ordering only with partially hydrophobic particles, the particle-meniscus interactions need also be considered.
