[Phase transitions in lyotropic liquid crystals: bilayer and micelle stability].

A model for describing hydrophile and hydrophobic interactions was introduced. On the basis of this model a phase diagram was calculated for transitions of homogeneous mixture amphyphyl--water into pure, intermediate and isotropic phases. Coefficients of the model introduced were found from the comparison with the experimental data. A relative role of electrostatic interaction was evaluated and compared with hydrophile and hydrophobic ones.
