Polarization features of polymer dispersed liquid crystal (PDLC) films were investigated experimentally. An alignment of PDLC films was achieved by a shear deformation of the films at an accurate control of geometric parameters. A numerical interpretation of experimental results was made for practical application An influence of droplets shape to the polarization features of the PDLC film was estimated.

Was synthesized two copper ( II ) complexes and one nickel complex of N-benzylidene-aniline derivatives and their ligands. We have performed polarized FTJIR spectroscopy and X-ray diffraction measurements in wide temperature range ( 0-220°C ) in order to establish correlation's among molecular, crystal and mesophase structures. We provided comparison of the FTIR and X -ray diffractometry results between well known metallo -organic copper ( II ) complexes, which crystallizes in the monoclinic space group C2/c, with similar nickel complex. Investigated ligands and their metallo -mesogens are displaying the same sequence of the liquid crystalline phases -only with higher melting temperature for metallo -complexes

Electrooptical characteristics of the polymer dispersed liquid crystal (PDLC) structure were estimated using Rayleigh-Gans scattering theory. This simple method suits for an approximate estimation of the influence of geometrical parameters ofthe PDLC structures on electrooptical characteristics. The conclusion has been made, that "threshold" voltage of the electrooptical response is caused by geometrical parameters of the PDLC structures mainly, but not by the properties ofthe LC.
