Abstract:
Liquid crystalline materials are ubiquitously applied to display devices in modern electro-optical technology. The dispersion of nanomaterials in liquid crystals (LCs) has created tremendous attention among various scientific communities due to the unique physical, mechanical and electrical properties of nanomaterials with liquid crystalline materials. These nanomaterials doped in liquid crystals have been studied for enhanced physical properties for display applications.
In the present work, very small concentration of one dimensional CdS nanoparticles (0.0, 0.1 and 0.3 wt./wt.%) was dispersed into ferroelectric liquid crystal material. The composites were prepared and studied between two indium tin oxide (ITO) coated glass substrates and separated by 4Aμm thickness mylar spacer. It was noticed that CdS nanoparticles have good coupling with FLC molecules because of the same structural behavior and a considerable impact on the spontaneous polarization and switching time has been investigated at the expense of increasing CdS nanoparticles concentration. The effect of bistability (memory effect) in doped samples has also been analyzed. A long lasting memory behaviour has been observed in doped samples even after the removal of bias voltage. Such kind of devices may be helpful in many display as well as non-display applications.
