Abstract

A theoretical order–disorder model for the main phase transition of lipid monolayers is presented here. The model contains approximate treatments of hard‐core repulsions and attractive forces between molecules. The lipid molecules are assumed as the square plates and then the entropy of the configurations is obtained using the placement method in a two‐dimensional lattice. The approximation used to compute the thermodynamic behavior of the model turns out to be a kind of molecular‐field approximation. The resultant pressure–density isotherms for the three‐state model show the characteristic van der Waals loops.
