The paper summarizes the results of a study on the basic properties (film thickness, contact angle film/meniscus and gas permeability) of foam films stabilized with the anionic perfluoro octane sulfonate (PFOS) surfactant. The surfactant was used as a tetraethyl ammonium salt. The dependencies on the electrolyte (NH 4 Cl) and surfactant concentration were studied. Strong dependence of the...
Properties of single foam films prepared with tetraethylammonium perfluorooctane-sulfonate (TAPOS) were studied. Film thickness was measured as a function of NH 4 Cl concentration in the film forming solution. The dependence of the film disjoining pressure versus the film thickness (disjoining pressure isotherms) and the mean lifetime of the films were studied. The dependence of the film thickness...
