Changing the size of oil droplets dispersed in water without added surfactants

Francis, Mathew; Boyson, Toby; Pashley, Richard M


Electrophoresis studies on pure hydrocarbon oil droplets, dispersed in water, have established that a significant charge is naturally developed on the droplets surface due to the spontaneous adsorption of hydroxyl ions. It has subsequently been pointed out that this charge should ensure the meta-stability of fine, micron-sized oil droplets dispersed in water. Further studies have demonstrated that such dispersions can be produced by the vigorous shaking of de-gassed mixtures of oil and water....[Show more]
