Résumé

We report the behavior of Newton and Common Black Films (NBF and CBF respectively) irradiated by a low power infrared source, for different kinds of surfactant. During irradiation, the film structure is continuously investigated by means of X-ray reflectivity. The irradiation reduces the film thickness by extracting water from the central core. Different processes are involved: evaporation of bonded water molecules through the aliphatic medium in the NBF and thermo-osmotic flow of liquid water in the CBF. In all cases the process is reversible when the irradiation is stopped.
