摘要

In order to establish the mutual miscibility of d,l-dipalmitoylphosphatidylcholine (DPPC) and 4-methylumbelliferyl palmitate in a two-dimensional phase monolayer behaviour have been investigated. For this purpose, the isotherms of surface pressure versus molecular area were measured for monolayers. A classical thermodynamic analysis was performed on these isotherms which involved calculating excess free energies of mixing to determine the miscibility properties. The work shows surface compatibility of DPPC and 4-methylumbelliferyl palmitate with the occurrence of attractive interactions between the two components.
