The main method to investigate foam films is the Thin Film Pressure Balance for measuring the disjoining pressure isotherms and optical observation of foam films. However, also surface-sensitive methods are used such as tensiometry (dynamic/static) and neutron scattering to study a single air/water interface. Surfactants, mixtures of polyelectrolytes and surfactants as well as proteins are investigated. We are interested in synergistic effects, the impact of additives (different polyelectrolytes, salt) and ion-specific effects.
