Abstract

A comprehensive thermodynamic analysis of Langmuir monolayers of two thiolipids has been carried out. Starting from the differentiated integral characteristic state functions for thin films, the consecutive partial derivatives were calculated and arranged to isothermal area derivatives, isobaric temperature derivatives and isoarea pressure derivatives. The obtained surface compressibility, surface expansivity and surface pressure coefficient parameters where then analyzed for the studied monolayers. These parameters appeared to be quite powerful in detecting the extension and sharpness of the characteristic co-operativity of the film-forming substances.
