Surfactants in a non-local model for phase transitions

Year: 2025

Type: article

Abstract: We investigate the influence of surfactants on stabilizing the formation of interfaces in nonlocal anisotropic two-phase fluid at equilibrium. The analysis focuses on singularly perturbed non-local van der Waals–Cahn–Hillard-type energies, supplemented with a term that accounts for the interaction between the surfactant and the fluid. We derive by Γ-convergence the effective surface tension model as the thickness of the transition layer vanishes and show that it decreases when the surfactant segregates to the interface.
