The Influence of polymer system on polymer-stabilised blue phase liquid crystals

The influence of polymer system on polymer-stabilised (PS) blue phase (BP) liquid crystal (LC) is investigated. After polymer stabilisation, anchoring energy appears between the polymer network and LC molecules, which is related with the stiffness of the polymer system. As the stiffness of polymer system decreases, the Kerr constant can be improved with the degradation of response time, hysteresis, and residual birefringence. Furthermore, the Kerr constant and response time can be improved simultaneously by polymer system with reactive diluents.
