Propriétés adhésives entre deux bulles de savon

Abstract : This work aims to characterize the static and dynamical adhesive properties of soap bubbles. To do so, we developed an experimental device allowing one to put into contact two soap bubbles of known composition. First, we observe and model the static deviation of the contact angle measured by image analysis from the predicted value of 120°. Next, we focus on the response of two bubbles submitted to a sinusoidal solicitation. Local angular modules are defined from the dynamic contact angle and the deformation of the contact radius and plotted as a function of the frequency. The observed viscoelastic behavior is compared to the dilational elasticity of the liquid films through a microscopic model. Liquid properties are modulated and their effect on the frequential diagram is discussed. Finally, we try to relate these adhesion properties to the macroscopic rheology of aqueous foams by correcting Princen model of elasticity.
