A patterned polymer dispersed liquid crystal transparent display using one-time UV exposure is demonstrated. The device fabricated by exposing the cell with a uniform light through mask selective attenuation of light. voltage-transmittance response different for corresponding regions. Thus, three states total scattering, transparent, and can be realized controlling applied voltages. proposed us...

FT-IR microspectroscopy is used to compare the polymer and liquid crystal droplet regions within polymer-dispersed liquid crystal (PDLC) films. Thermoplastic polymer matrix PDLCs contain a higher amount of liquid crystal within the polymer regions than do thermoset polymer matrix films. IR functional group images of a droplet show characteristic textures corresponding to the visual images of th...

Monte Carlo simulations of lattice spin models represent a powerful method for the investigation of confined nematic liquid crystals and allow a study of the molecular organization and thermodynamics of these systems. Here some models of confined liquid crystals, such as polymer dispersed liquid crystals, twisted nematic, in-plane switching liquid crystal displays and hybrid aligned films are d...

Temperature effect on lasing from a Penrose photonic quasicrystal made of low index contrast materials holographic polymer dispersed liquid crystals was investigated. A blue-shift of lasing peak was observed with increased temperature in the range of 25 °C~50 °C. The transmission spectra of Penrose photonic quasicrystal was studied through FDTD simulation, which showed a correlation between the...

Polymer-supported liquid-crystal membranes have been designed for neutral-carrier-type potassium ion-selective electrodes, aiming for practical applications of high-performance liquid-crystalline membrane ion sensors. Two types of polymer-supported liquid-crystal membranes were tested for their usefulness; one is microporous poly(tetra fluoroethylene) (PTFE) membranes impregnated by thermotropi...
