Polymer stabilized isotropic phase liquid crystals with large Kerr constant

ABSTRACT

In this paper, we reported a polymer stabilised isotropic phase liquid crystal (PSILC). The influences of different content of chiral dopant and polymer monomer on PSILC were studied. Adding the proper proportion and total content of polymer monomer TMPTA and C12A into liquid crystal with 1.0 wt.% chiral dopant R5011, and UV photo-polymerisation at the isotropic phase, we obtain the Kerr constant greater than 10 nm/V², hysteresis less than 2.0% and fast response in PSILC.
