Electrically tunable polarisation-independent blue-phase liquid crystal binary phase grating via phase-separated composite films
(Taylor & Francis Ltd, 2017)
A simple method for fabricating polarisation-independent blue-phase liquid crystal phase grating is demonstrated by implementing photopolymerisation-induced phase separation through a binary photomask. The dynamic focusing ...
Investigation of the viscoelastic properties of 4-propoxy-biphenyl-4-carbonitrile
(Taylor & Francis Ltd, 2019)
We report on the temperature-dependent measurements of dielectric permittivity, birefringence, elastic constants and rotational viscosity for 4-propoxy-biphenyl-4-carbonitrile in the nematic region. The temperature dependence ...
Switchable polarisation-independent blue phase liquid crystal Fresnel lens based on phase-separated composite films
(Taylor & Francis Ltd, 2017)
A simple method for fabricating a polarisation independent blue-phase liquid crystal Fresnel lens (BPLCFL) is demonstrated by utilising the photo-polymerisation-induced phase separation. The BPLC/polymer binary Fresnel ...
The influence of diluter system on polymer-stabilised blue-phase liquid crystals
(Taylor & Francis Ltd, 2018)
In the present work, diluter effects on the phase transition temperatures and electro-optical properties of the polymer-stabilised blue-phase liquid crystals with microsecond respond time have been carried out. The temperature ...
High-diffraction-efficiency Fresnel lens based on annealed blue-phase liquid crystal-polymer composite
(Taylor & Francis Ltd, 2019)
We demonstrated a relatively simple and effective method to fabricate a periodically isolated polymer wall of blue-phase liquid crystal Fresnel lens (BPLCFL) by employing a single-masking process of the ultraviolet (UV) ...
Viscoelasticity, dielectric anisotropy, and birefringence in the nematic phase of three four-ring bent-core liquid crystals with an L-shaped molecular frame
(Royal Soc Chemistry, 2013)
Molecular shape is an important factor in determining the material properties of thermotropic liquid crystals (LCs). We synthesized and investigated several LC compounds formed by asymmetrically bent molecules with a rigid ...
