Abstract
Liquid crystals (LCs) are one of the most important materials for electronic devices. High chemical resistance, optical and other properties lead to development of scientific research in the field of creating chemical and biological sensors. The creation of an LC film doped with nanoparticles (NPs) and exhibiting surface plasmon resonance can facilitate the appearance of an optical response of the film structure. This could contribute to the development of new sensory devices. Langmuir method allows to dope of LC matrix by NPs during film formation. Studies have shown that the introduction of copper NPs stabilized by surfactant sodium dodecyl sulfate (SDS) leads to an increase in the area occupied by the 4-n-octyl-4'-cyanobiphenyl (8CB) monolayer and to an increase in the monolayer collapse pressure without disturbing the domain structure of the LC monolayer. This occurs due to the adsorption of copper NPs stabilized by SDS on the subphase surface.
