摘要
The present invention comprises a fumed metal-oxide gel, such as fumed silica gel, that is dispersed into a blue-phase liquid crystal. Adding the fumed silica nanoparticles in blue-phase media leads to the broadening of the blue-phase temperature range and reduces the switching voltage. Additionally, the polarity-controlled nanoparticles of the fumed silica enable the stabilization of thermal-sensitive Bragg reflection property of the blue-phase liquid crystals, which allows their use in active optical elements and fast-switching LCDs.
