Abstract

Monolayers of synthetic lecithins as well as phosphatidic acid at different stages of ionization were studied with the film balance technique at pressures above the lateral vapor pressure. Pressure ( pi ) versus area (a) curves (isotherms) and, by application of a special technique, area (a) versus temperature (T) curves (isobars) were recorded. From these data, plots of the lateral compressibility, CHI , as a function of lateral lipid density (a** minus **1) and of the thermal expansion coefficient, alpha , as a function of temperature (T) were obtained.
