In this study, we explored how chemical reactions of amphiphile compounds can be characterized and followed-up on model interfaces. A custom-made surfactant containing three alkyne sites was first adsorbed and characterized at a water/oil interface. These amphiphiles then underwent interfacial crosslinking by click chemistry upon the addition of a second reactive agent. The monolayer properties and dilatational elasticity, were compared before and after the polymerization. Using bulk phase exchange, the composition of the aqueous bulk phase was finely controlled and washed to specifically measure the interfacial effects of the entities adsorbed and trapped at the interface. In this study, we aim to emphasize an original experimental approach to follow complex phenomena occurring on model interfaces, and also show the potential of this method to characterize multifactorial processes.
