Abstract

The classical Frankel law describing the formation of soap films was recently found to break down for polymer solutions. We discuss in this paper how this could be due to the effects of normal stresses and slip of the polymer along the surfactant-covered surfaces. We also study the consequences of a detailed description of the surface layer including the Marangoni effect, in the case of soluble surfactants (using tiie classical Gibbs theory) as well as in the case of insoluble surfactants. These predictions are compared to experimental results.
