MoS 2 nanoparticles, speed, VIS and IR spectra, contact angle, rotation of polarization plane of lightThe analysis of experimental results on time and spectral parameters, effect of interface on wetting, effect of rotation of light polarization plane of the nematic liquid crystal -MoS 2 nanoparticle system was carried out. Investigations were performed in terms of further possible use of these systems for display elements, light modulators and rotators of light polarization plane. The wetting angles of the conductive contacts surfaces created by the innovative structure were established, which makes it possible to obtain the oblique orientation of liquid crystal compositions without application of direct orienting layer. The rotation angle of the light polarization plane was determined. Quantum mechanical calculations of such systems have been performed for the first time.
