Smart Windows Based on Polymer Stabilized or Dispersed Liquid Crystal

  • 摘要: 文章介绍了聚合物稳定液晶(polymer stabilized liquid crystal,简称PSLC)和聚合物分散液晶(polymer-dispersed liquid crystal,简称PDLC)的研究现状,包括聚合电场频率、不同单体配比、聚合网络的锚定作用、单体浓度、聚合电场波形、单体BAB6和手性剂含量对聚合物稳定胆甾相液晶光电性能的影响和不同醇、表面活性剂、阻聚剂、紫外光固化时间、纳米掺杂、液晶含量和引发剂含量、聚氨酯基对聚合物分散液晶电光特性的影响.通过研究液晶单体浓度、PI膜厚度、二色性染料浓度和二色性染料的种类对PSLC器件光电性能的影响,表明液晶单体浓度为3%、PI膜厚度为80nm、二色性染料浓度为0.6%时, PSLC器件的光电性能最好.基于聚合物稳定液晶的智能调光玻璃在车窗玻璃,家居玻璃窗等方面有着良好的应用前景.

     

    Abstract: This review summarizes the works of PSLC(polymer stabilized liquid crystal,PSLC) and PDLC(polymer-dispersed liquid crystal,PDLC), including the effects of polymerization field frequency, monomer ratio, anchoring effect of polymerization network, monomer concentration, polymerization electric field, monomer BAB6 and chiral agent content on the photoelectric properties of PSLC and the effect of different alcohols, surfactants, inhibitors and UV curing time, nano-doped, liquid crystal content and initiator content, Polyurethane on electro-optic characteristics of PDLC. The effects of the concentration of liquid crystal monomer, PI film thickness, dichroic dye concentration and dichroic dye on PSLC performance were investigated. The results show that the optimized condition of photoelectric properties of PSLC are that the concentration of liquid crystal monomer is 3%, the thickness of PI film is 80nm and the dichroic dye concentration is 0.6%. The intelligent dimming glass based on polymer stabilized liquid crystal has a good application prospect in buildings, automobiles and so on.
