Résumé

A soap film (made of two air/water interfaces covered by surfactant) may turn into a so-called Newton black film (NBF) which essentially consists in a surfactant bilayer. Oil-in-water emulsion droplets covered with surfactant (oil/water interfaces) may become adhesive in similar conditions. We show by analyzing the neutron scattering pattern from a collection of submicronic oil-in-water adhesive droplets that the thin film that forms between them is structurally identical to the NBF. As a consequence, the formation of NBF is a general property of ionic surfactants.
