Paper Abstract

We report on dispersion of a small amount of colloids in a blue phase liquid crystal, and the blue-phases were found to exhibit extended temperature range. The stabilized temperature range of the blue phase was a function of their most effective concentration, different sizes of colloid particles and shape of colloidal particles. The temperature range was probed and determined and the temperature range of the blue phases was found to decrease as the colloidal particle size increased. Additionally, the temperature dependent of Bragg wavelength peak was found to redshifted in the colloidal-BP mixtures. The electro-optical results, especially the switching voltage and response time suggested that concentration and size of dispersed colloids modified the elastic energy of the blue phase liquid crystal composites and led to a lower switching voltage.
