چکیده

We have investigated diluter effects on the Debye relaxation frequency, and electro-optics of polymer-stabilized blue phase liquid crystals (BPLC). The relaxation frequency can be increased by adding a small amount of diluters, which benefits high frequency operation of BPLC. Some diluters significantly decrease the BPLC response time while maintaining similar Kerr constant. Author

Dynamic response of a blue phase to an applied field

The dynamic response of the three-dimensionally ordered blue phases BPI and BPII to a step-function electric field was studied in a liquid crystal with negative dielectric anisotropy. A change of diffraction intensities, indicating the existence of two qualitatively different transformations of the structure, has been observed in a pulse electric field.

Viewing angle controllable displays with a blue-phase liquid crystal cell.

We demonstrate a controllable viewing angle liquid crystal display (LCD) using an inserted blue-phase liquid crystal (BPLC) cell. The BPLC layer functions as a tunable positive C-film or a negative C-film, depending on whether the employed LC has a positive or negative dielectric anisotropy. Therefore, the viewing angle of the LCD panel can be controlled continuously by the applied voltage of t...

Nematic anchoring on carbon nanotubes

A dilute suspension of carbon nanotubes CNTs in a nematic liquid crystal LC does not disturb the LC director. Due to a strong LC-CNT anchoring energy and structural symmetry matching, CNT long axis follows the director field, possessing enhanced dielectric anisotropy of the LC media. This strong anchoring energy stabilizes local pseudonematic domains, resulting in nonzero dielectric anisotropy ...

Dielectric dispersion on the Kerr constant of blue phase liquid crystals

Dielectric dispersions on the Kerr constant of two polymer-stabilized blue phase liquid crystals (BPLCs) are investigated. An extended Cole-Cole model is proposed to fit the experimental results and good agreement is obtained. As the electric field frequency increases, Kerr constant decreases and the associated dielectric heating effect gradually increases. These results will undoubtedly affect...
