ABSTRACT
The two-dimensional rheology of uid interfaces has been a subject of numerous studies, because of its link with the stability of foams and emulsions (Langevin 2000; Wilde 2000). Basically, when the stress response to deformation is stronger, this immobilizes the surfaces and the thin lms and prevents them from being disturbed too much, and the dispersion is stabilized. Experimental measurements with various systems, containing surfactants, proteins, polymers, and so on, have revealed that the interfacial rheological behavior is often of the viscoelastic type (Sagis 2011).
