Abstract
ABSTRACTStructure of an oriented layer of mesogens on the interface at the isotropic phase (IP) – nematic liquid crystal (NLC) transition has been studied by polarization microscopy method. The thickness of the oriented layer was found to be equal to 50 ÷1000 µm, it decreases with a reduction of the surface curvature radius. Analytical expressions for the phase delay difference arising at passing of plane-polarized light through the mesogen layer oriented towards cylindrical and spherical surfaces have been obtained. The order parameter in mesogens at the IP-NLC transition was determined.
