Surface electroclinic effect in ferroelectric liquid crystal

Surface electroclinic effect in chiral nematic IN") phase of high-tilt-angle ferroelectric liquid crystal has been studied by dielectric relaxation and electro-optical method in a homogeneously aligned, thin samples in the frequency range of 400 Hz to loo kHz at different temperatures. The electroclinic effect in the N* phase observed in the surface layers is due to the effect of surface anchor...

Dielectric relaxation in a ferroelectric liquid crystal

2014 We present an analytic calculation of the normal modes of distortion induced by a small transverse A.C. electric field on a ferroelectric liquid crystal close to its transition temperature Tc between the smectic A and C* phases. These normal modes are superpositions of electric polarization and angular molecular distortion. Compared to a previous work of Blinc and Zeks, we assume that the ...

Ferroelectric liquid crystalline polyoxetanes bearing chiral dimesogenic pendants

Two new polyoxetanes bearing dimesogenic pendants were prepared and their liquid crystalline properties were studied by differential scanning calorimetry (DSC), polarizing microscopy, and X-ray diffractometry. The dimesogens consist of cholesterol and biphenyl moieties connected through polymethylene spacers. Their biphenyl ends were attached to the oxetane monomer through a hexamethylene unit ...
