制备出较大微滴聚合物分散胆甾相液晶样品,用偏光显微镜观察到该微滴具有奇特的宝石形貌。提出聚合物分散胆甾相液晶中液晶微滴有垂面和沿面螺旋新构型,与聚合物分散向列相液晶的双极和辐射分布构型相对应,认为宝石形貌可能对应着胆甾相液晶在微滴中呈现沿面螺旋与垂面螺旋构型简并共存多畴形貌。本实验研究具有液晶光学基础研究意义和设计新型液晶器件的实用参考价值。
Polymer dispersed cholesteric liquid crystal samples with large droplets were made
and the droplets had strange "gem" texture by polarizing microscope. The new vertical helix and parallel helix configuration in the polymer disperse cholesteric liquid crystal droplets were proposed. Considering the bipolar and radiation configuration of polymer disperse nematic liquid crystal
the "gem" texture may correspond with degeneracy coexistence of multi domain texture of vertical helix and parallel helix configuration. This experiment had basic research significance for liquid crystal optics and reference value to design the new liquid crystal device.
