Abstract: Semifluorinated alkanesFnHmself‐assemble into nanometer‐sized surface micelles at the air‐water interface. In this study, we investigated how an atmosphere enriched with perfluorohexane (PFH) influences the interfacial viscoelasticity and structural order of a monolayer ofFnHmby the combination of dilational rheology and grazing‐incidence small‐angle X‐ray scattering (GISAXS). The monolayers behaved predominantly elastic which can be attributed to the strong dipole repulsions of the surface domains. Enrichment of the atmosphere with PFH lead to an increase of the compressibility and a decrease of the elastic modulus without altering the structural ordering of theFnHmmolecules into highly correlated nanodomains, suggesting the adsorption of PFH molecules to the free spaces between the domains. The capability ofFnHmdomains to retain the structural integrity in the presence of PFH gas is promising for the fabrication of stable microbubbles for sonographic imaging.
