Abstract

Free surface of one amphiphilic molecule head of a lyotropic liquid crystal has been investigated by X-ray diffraction method, at small and large angles, in the presence of the third component. The pentadecylsulphonate-water system in the presence of cholesterol as well as the lecithin-water system in the presence of decanol were investigated. It is shown that the above mentioned free surface decreases if the cholesterol concentration increases, while this surface increases in the case of water concentration increase. However, it increases slower than in the case of the two-component system. The same is observed for the lecithin-water-decanol system.
