Phase Transition and Electro‐Optic Studies in Polymer Stabilized Blue Phase Liquid Crystal

Summary In the present work, polymer stabilized blue phase liquid crystal have been prepared by mixing blue phase liquid crystal, mono-functional monomer, bifunctional monomer and photo initiator in a weight ratio of 93.5:3:3:0.5 respectively. Blue phases, BP-I and BP-II were observed during heating and cooling cycles. Polymer stabilized blue phase having a temperature range of 14.8°C and Kerr constant 1.23 nm/V2 was observed. Hysteresis effect measured in the polymer stabilized blue phase liquid crystal was almost negligible.
