| Popis: | 98 This study of the use of synthetic lactic acid structures with double chiral centres liquid crystal (LC) material, in the experiment with polarized optical microscopy (POM) observation of the liquid crystal material from the isotropic temperature down to appear chiral smectic A phase (SmA*), it will produce the homeotropic texture of the LC phase; So, we hope that the SmA* phase LC materials by mixing photo-induced vertical alignment (VA) of the negative dielectric anisotropy LC (Nematic type LC)/acrylic monomer mixture systems, in order to auxiliary LC molecules to achieve the overall effect of the vertical arrangement of one of the main purpose of this experiments. The LC mixture systems in this VA mode, we observe the LC molecules arrangement condition by POM and the use of differential scanning calorimeter (DSC) to investigate the LC phase-transition behaviors. Finally, for the preliminary gray-scale characteristics of the LC mixture systems is also being explored. |
