Stabilization of monolayers and Langmuir-Blodgett films of mesogenic components by mixing

To study the influence of their interaction on the monolayer properties, we have investigated pure and mixed films of two thermotropic liquid crystalline substances ▪ with regard to film pressure-area F-A behaviour, monolayer stability and ability to form Langmuir-Blodgett (LB) films.

Description
Summary:To study the influence of their interaction on the monolayer properties, we have investigated pure and mixed films of two thermotropic liquid crystalline substances ▪ with regard to film pressure-area F-A behaviour, monolayer stability and ability to form Langmuir-Blodgett (LB) films. The pure components occur only in the expanded state. At constant pressure the area drops rapidly, indicating low film stability. The mixed films form condensed films, whereby 1:1 mixtures exhibit the strongest reduction in area. These films are very stable. They can easily be transferred onto hydrophobic substrates. The LB films are to the Y type, which is confirmed by X-ray investigations.
