Influence of interaction energy in fluid-fluid phase transitions on Langmuir monolayers

Influence of interaction energy in fluid-fluid phase transitions on Langmuir monolayers

A pure lattice model for Langmuir monolayers is presented where only nearest neighbor interactions are considered. The flexibility of hydrophobic tails laying on the surface is taken into account but the segments above the surface are taken as upstanding rigid rods without contribution to the entropy. The numerical calculations show that to obtain more than one phase transition the flexibility of these tails has to be taken into account.
