Surfactant films in lyotropic lamellar (and related) phases: Fluctuations and interactions

摘要

AbstractThe analogy between soap films thinning under border capillary suction and lamellar stacks of surfactant bilayers dehydrated by osmotic stress is explored, in particular in the highly dehydrated limit where the soap film becomes a Newton black film. The nature of short-range repulsive interactions between surfactant-covered interfaces and acting across water channels in both cases will be discussed.Graphical AbstractDisplay OmittedHighlights?Black soap films and dehydrated lamellar phases are structurally similar.?Closely related fluctuations and interactions are relevant in both systems.?Spinodal instabilities are relevant in both systems.]]>
