Abstract

Electrodes and alignment layers are major components of practically any liquid crystal device. Typically, indium-tin oxide films serve as electrodes (to apply an external voltage across the liquid crystal layer) whereas polyimide-based polymers (alignment layers) provide the required alignment of liquid crystals. Conducting polymers can combine the afore-mentioned two functions thus serving as both electrodes and alignment layers. In the majority of the reported studies, highly conducting polymers were used. On the contrary, in this paper, we report on electro-optics of liquid crystal cells utilizing weakly conducting polymers. Both static and time electro-optical response are analyzed. The designed cells are characterized by some interesting electro-optical features including the dependence of the effective threshold voltage on the frequency (0-1000 Hz) of the applied electric field. The model of this frequency dependence of the effective threshold voltage is discussed. Our results suggest that weakly conducting polymers are very promising materials for the development of flexible and wearable liquid crystal devices.
