Abstract

Recently, modulated phases of insoluble monolayers of fatty acids and phospholipids spread on the water/air interface have been observed by fluorescence microscopy experiments. We propose a theoretical explanation of this observation by including electrostatic (dipolar) interactions in the total free energy calculation for the monolayer. Dipoles can originate from two sources: neutral amphiphiles have a permanent dipole and charged amphiphiles have an induced one. Modulated phases are found to be stable in two different limits: close to the liquid-gas transition and at low temperatures. Several phases with stripe and hexagonal symmetry are predicted and the phase transitions between them are calculated.

36. The exact summation of the inter-stripe electrostatic interactions is performed in ref. 31 and is shown also in ref. 30. In ref. 29, the identical inter-stripe contribution is expressed as an infinite sum. Taking only the first few terms in the infinite sum gives qualitatively similar results.Google Scholar
