The Effect of Polymer Structures on Polymer Stabilized Blue Phase Liquid Crystals
Journal Title: Cumhuriyet Science journal - Year 2017, Vol 38, Issue 4
Abstract
In the present work, the effects of polymer structures on blue phase liquid crystals were carried out. Blue-phase liquid crystal samples with wide temperature range including room temperature were obtained by means of the polymer network formation. The temperature range of each sample with polymer-stabilized blue phase liquid crystal is at least C. The experimental results show that the electro-optical performances of blue phase are influenced by the interaction energy between the liquid crystal molecules and polymer network structure. As the anchoring energy of polymer network increases, the operating voltage increases. The response time of samples with high anchoring energy is faster and the kerr constant and hysteresis of those are smaller. In addition, the Kerr values of all samples are at least two orders of magnitude larger than that of nitrobenzene.
