光聚合时间对液晶高分子红外反射器件光电性能的影响

Effect of Photo-Polymerization Time on the Photoelectric Properties of Infrared Reflectors based on Polymer Liquid Crystals

  • 摘要: 本文基于聚合物稳定胆甾型液晶制备了红外反射器件。在外加电场的作用下,聚合物网络中附着的阳离子朝阴极运动,使得靠近阴极附近的网络被压缩,而靠近阳极附近的网络被拉伸,结果使得整个胆甾相想成一定的螺距梯度,从而使得反射带宽变宽。进一步在不同紫外光聚合时间条件下制备电控红外反射器件,光电性能呈现规律性的变化。本文主要根据红外反射器件的光聚合时间不同来探究其对液晶高分子红外反射器件光电性能的影响。

     

    Abstract: In this paper, an infrared reflector was fabricated based on polymer stabilized liquid crystal. The positive charge impurities in the mixture trapped by the polymer network delocalized on application of a DC electric field causing the polymer network shrink near the cathode, expanding near anode, which leads to pitch gradient, resulting in the reflection bandwidth broadening. The photoelectric properties of the electronically tunable infrared reflectors prepared under the different UV polymerization time was investigated.
