Interfaces properties and confinement effects of complex fluids are involved in stabilization of foams. This question is also related to micro-fluidics and nano-fluidics, which have been developed during recent years.Mixed solutions made of polyelectrolytes and surfactants have been used to study the influence of both confinement and surfactant in ultra-thin films (< 100 nm). Dissipation in these films was probed by using a thin film pressure balance as a rheometer and an hydrodynamics model. An effective viscosity can be extracted, which is higher for thinner films and affected by the nature of the surfactant.Generation of thicker films (a few microns) by dip coating of a solid plate enables to rule out the confinement. Several surfactants...
