چکیده

Ultrasmall-angle synchrotron X-ray scattering measurements showed that a three-dimensional polymer lattice of a few 100 nm order with body-centered cubic O(8-) symmetry was formed in a polymer-stabilized blue phase liquid crystal. We obtained clear experimental evidence that the polymer chains condensed selectively in the disclinations within the blue phase during photo-polymerization of monomers in the blue phase.

Electrically switched color with polymer-stabilized blue-phase liquid crystals.

We report an electrical-field switched color device using a polymer-stabilized blue-phase (PSBP) liquid crystal in which the Bragg-reflected color of the blue phase (BP) can be switched to reflect a second color. The phase-separated three-dimensional polymer network transcribes the cubic structure of a BP liquid crystal and restrains the deformation of cubic lattice by the external electric fie...

Emerging Polymer-Stabilized Blue Phase Liquid Crystal Display

Polymer-stabilized blue-phase liquid crystals hold great potential for future display applications. Some technical challenges, such as blue-phase temperature range, operation voltage, hysteresis, and voltage holding ratio remain to be overcome before widespread commercialization can be realized. In this paper, we review recent advances in this emerging technology.

Polymer-Stabilized Blue-Phase Liquid Crystal Cured with a Visible Laser

We report a polymer-stabilized blue-phase liquid crystal (PSBPLC) cured with a visible laser in an in-plane-switching (IPS) cell. Its electro-optic properties are compared with those of a conventional PS-BPLC cured by ultraviolet (UV) light. Besides, a PS-BPLC grating is fabricated using visible-laser holography. Author

Polymer-stabilized blue-phase liquid crystal grating cured with interfered visible light.

In this paper, we demonstrate a holographic polymer-stabilized blue-phase liquid crystal grating fabricated using a visible laser. As blue phase is stabilized by the interfered light, polymer-concentration gradient is achieved simultaneously. With the application of a uniform vertical electric field, periodic index distribution is obtained due to polymer-concentration gradient. The grating exhi...
