Paper Abstract

The experimental results on thermo- and electro-optical properties of two liquid crystalline model dimers: disiloxane and disilazane and their blends with polyester resin (Polimal 192) are reported. The effects of temperature, voltage, and frequency of alternating electric field on electro-optical and switching results are discussed. Siloxane dimer shows a tendancy to planar orientation of molecules in (ac) electric field resulting from its negative dielectric anisotropy. Silazane dimer shows the trend toward homeotropic orientation of molecules, which is disturbed by the occurrence of an electrodynamic instability involving turbulent flow (at 2 kHz applied voltage.
