Harvested ferroelectric nanoparticles of BaTiO3 and LiNbO3 were dispersed in Ferroelectric Liquid Crystals FLCs with very high spontaneous polarization Ps. The electrooptic and dielectric parameters were documented. The dipoles of ferroelectric nanoparticles and those of FLCs are partially cancelled in an antiparallel manner. The role of cell parameters like thickness of the Nylon 6 polymer layer and the change in preparation of the polymer layer due to different mechanical rubbing cycles has been described for one high-Ps FLC and for high-Ps FLCBaTiO3 nanocolloids. Cell properties depend strongly on anchoring forces which might interact with dipoles both from ferroelectric nanoparticles and high-Ps FLCs.
