We investigated dielectric properties of a hockey-stick-shaped liquid crystal (HLC). Two dielectric relaxation modes were observed at 0.91 kHz and 4.51 MHz. The low frequency relaxation modes in isotropic, smectic, and nematic phases are related to the motion of ions, collective tilt fluctuation, and rotation around the long molecular axis, respectively. Meanwhile, the high frequency relaxation modes in nematic and smectic phases was due to the rotation around the short axis of the molecules and hindered by the resistance of the ITO layers. We also examined the electrooptical response of the 5.0 wt% HLC-doped commercial nematic liquid crystal (LC) mixtures. The birefringence of the LC mixture was slightly increased, while the falling time and the rotational viscosity was decreased in the nematic phase.

我们研究了曲棍球棒状液晶（HLC）的介电性能。在0.91 kHz和4.51 MHz处观察到两种介电弛豫模式。各向同性，近晶和向列相的低频弛豫模式分别与离子的运动，集体倾斜波动和绕长分子轴的旋转有关。同时，向列相和近晶相的高频弛豫模式是由于绕分子短轴的旋转，并受到ITO层电阻的阻碍。我们还检查了5.0 wt％的HLC掺杂商用向列液晶（LC）混合物的电光响应。在向列相中，LC混合物的双折射略有增加，而下降时间和旋转粘度降低。
