Abstract
The presence of solid nano-scale particles affects the stability of emulsions but it is difficult to make direct observations of these particles because of their dimensions. By reducing the gravitational force exerted on the droplets and particles, it is possible to enlarge the emulsion droplet system and optically observe the particles on the interface. Such a macroscopic model of a solidsstabilized emulsion droplet has been developed using silicone oil, water and glass beads. The macroscopic system behaved similarly to colloidal scale emulsion systems in that beads protruding from the interface prevented coalescence. The behavior observed in the model system helps explain some previously published nanoscale solids-stabilized emulsion results and is consistent with the location of particles at fluid interfaces being influenced by: hydrophobicity, starting phase, line tension and van der Waals attraction.
