Paper Abstract

The liquid crystal director-colloidal particle surface interaction in filled liquid crystals causes the thermally-induced director fluctuation correlations to be screened. This is consistent with the experimentally observed reduction in the thermal director fluctuation-induced Rayleigh light scattering in filled liquid crystals. The colloid-mesogen interaction also induces director non-uniformity in filled liquid crystals, thus further modifying the spatial dependence of the director fluctuation correlations, and shifts the critical temperature at which the isotropic phase loses its stability with respect to nematic fluctuations. The shift is specifically particle-size dependent, and this will enable the phenomenon to be recognized experimentally.
