Liquid foams are widely used in industry and in everyday life. However, their stability is not fully understood or fully controlled, their formulation being essentially empirical. It is therefore difficult to predict the ability of a surfactant solution to generate foam and to control their destabilization. This thesis proposes simple experiments that rely on the multi-scale nature of foams in order to attempt to establish clear links between physical chemistry and stability.First of all, we revisited an experiment of liquid films entrainment to illustrate the stability of foam films during generation or rearrangement (T1 process). We have shown the existence of two regimes: (i) a unconfined regime, for which the stability of films is reduc...
