摘要

We have investigated a new form of polymer dispersed liquid crystals (PDLC) electro-optical films comprised of blue phase liquid crystal and polymer prepared by the solvent evaporation method. In this method, polymer dispersed blue phase (PDBP) films, which were laminated between two indium-tin-oxide-coated conductive substrates, demonstrated two switching modes between light scattering and transparent states in response to an applied electric field across the film. The electro-optical properties of PDBP liquid crystals can be altered by changing the concentrations of liquid crystal and polymer. The compositions, film preparations, physical and morphological behaviors, and electro-optical properties of PDBP films are described.
