Abstract
Electro-optic performance of a liquid-crystal (LC) system is enhanced by TiO2 nanoparticle dispersed in nematic liquid crystal (NLC). The 2.5 V threshold voltage of LC for device operation is lowered to 0.5 V through TiO2 nanoparticle mixing up to 2 wt.%. To characterize the shape and size distribution of the nanoparticles, high-resolution transmission electron microscopy is employed. Transmittance spectra for the TiO2 dispersed LC structure and nondispersed LC structure showed that transparency of the TiO2 dispersed LC is similar to that of pure liquid LC.
