  • Analysis of structural organization at the nanoscale within these films.
  • Comparative study of inorganic-surfactant films and polyelectrolyte-surfactant membranes.

    • Main Results:

    • Interfacial films can be several microns thick and exhibit highly organized nanoscale structures aligned with the interface.
    • Similar nanostructures are observed within recently developed polyelectrolyte-surfactant membranes.
    • Key links between these two distinct film systems are identified.

    Conclusions:

    • Air-solution interfacial films represent an under-explored area with significant materials potential.
    • The organized nanoscale structures are a key feature across different film compositions.
    • Understanding the relationship between these systems can advance materials design for interfacial applications.
