A study was conducted to demonstrate nanorod-driven orientational control of liquid crystal (LC) for polarization-tailored elector-optic devices. The dispersion of ultra-narrow ZnS nanorods encapsulated by a soft organic layer in nematic LC ZLI-4792 produced a soft-matter-type blend with robust electro-optic properties. It was found that the ultra-small nanorods had an inherent dipole moment, which showed high miscibility in the LC host and produced well-organized locally aligned arrays. It was observed that this local ordering influenced the global ordering of the blend and allowed a rapid response of the electro-optic properties. The study concluded that the blend exhibited excellent tunable polarizations from vertical to grazing view angles and adjustable anisotropy for the improvement of contrast ratios and view angles of LC displays.
