Influence of barium titanate particles on electro-optic characteristics of liquid crystalline mixture H-37

It was shown that the presence of barium titanate particles in H-37 decreases the clearing point, increases the threshold of the Freedericksz effect, and decreases the voltage of the electrohydrodynamic instability formation. A rise time increases and a decay time decreases in comparison with the pure H-37 at Williams' domains formation. First of all, experimental results were explained by appearance of local electric fields near the polarized ferroelectric particles at application of external electric field and also a change of effective viscosity and elastic properties of LC, existence of the additional obstacles (particles) at movement of ions.
