Abstract

IT has long been known that a liquid drop at an oil/aqueous interface does not coalesce spontaneously, the drop resting at the interface for some time before coalescing1. This rest time phenomenon is attributed to the presence of a thin film of the surrounding liquid (the continuous phase) trapped between the drop and the interface, as shown in Fig. 1 (refs. 2–4). This film drains radially under the influence of gravitational forces until it is approximately 1–10 µ in thickness, when rupture and subsequent coalescence take place.
