The sampler-Langmuir trough-Wilhelmy filter paper plate system `cuts out' an undisturbed film-covered sea area to perform pi-A studies without any initial physico-chemical sample processing. The limiting specific area Alim (2.68-31.57 nm2/molecule) and mean molecular mass Mw (0.65-9.7 kDa) of microlayer surfactants were determined from the 2D virial equation of state applied to the isotherms. Enthalpy deltaH and entropy deltaSt of the 2D first-order phase transitions were evaluated using the Clausius-Clapeyron equation applied to the isotherms. Miscibility of film components and film structure evolution is expressed by the scaling exponent y adopting the 2D polymer film scaling theory. The stress-relaxation measurements revealed a two-step relaxation process at the interface with characteristic times T1=1.1-2.8 and T2=5.6-25.6 seconds suggesting the presence of diffusion-controlled and structural organisation relaxation phenomena. The obtained results suggest that natural films are a complex mixture of biomolecules covering a wide range of solubilities, surface activity and molecular masses with an apparent structural organisation exhibiting a spatial and temporal variability.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Structural and thermodynamic signatures of marine microlayer surfactant films","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-17 01:31:30.050572","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"southern Baltic; Gulf of Gdansk; surfactant films; isotherm scaling;surface thermodynamics; visco-elasticity","OtherDescriptors":null,"Notes":null,"AnaPub":2003,"MonPub":null,"DateUpdate":"2021-02-18","DateCreate":"2003-07-15","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000183922600012","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/s1385-1101(03)00038-8"},"refs":null,"anarec":{"AnaID":36298,"PubliDate":2003,"Pagination":"347-356","XtraPublOfAnaID":null,"ISBN":null,"Volume":"49","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43261,"SerRR":"Journal of Sea Research.
