The influence of diluter system on polymer-stabilised blue-phase liquid crystals

In the present work, diluter effects on the phase transition temperatures and electro-optical properties of the polymer-stabilised blue-phase liquid crystals with microsecond respond time have been carried out. The temperature range of polymer-stabilised blue-phase samples broadened over 50 K including room temperature. By increasing the concentration of diluter, the faster response time is obtained, but Kerr constant become smaller. These values are still two orders of magnitude larger than conventional Kerr materials such as nitrobenzene. The major bottleneck is the increased operating voltage. Hysteresis is sensitive to the diluter concentration and is slightly small for polymer network systems. For next-generation display technology, an optimal concentration of diluter plays a crucial role to a proper balance between response time and operation voltage.
