摘要： A liquid crystal light composite in which discrete volumes of a liquid crystal material are dispersed in a matrix material is produced by a process in which a reactive additive formulation is added and photopolymerized. The reactive additive formulation includes mono- and multifunctional compounds in specified proportions and a photoinitiator. The reactive additive formulation reduces the operating field and may also improve other electro-optical properties.

摘要： A composite material (22) includes droplets (24) of a liquid crystal material dispersed within a matrix (26) of a photopolymerized polymer. The material (22) is prepared by forming a solution of the liquid crystal material and a monomer, and then polymerizing the monomer with light. The solubility of the liquid crystal material in the polymer is less than in the monomer. As polymerization progresses, a portion of the liquid crystal material separates as a second phase in the polymer matrix (26). The liquid crystal can be any suitable such material that is soluble in the monomer and less so in the polymer, and the monomer is a polymerizable acrylate or methacrylate. Liquid crystal devices are prepared by forming the composite material between two electrically conducting substrates.

摘要：一种PDLC薄膜的制备方法，通过将液晶（11）与石墨烯纳米粒子（12）混合形成第一溶液（1），采用柠檬酸（21）与1,8-辛二醇（22）制备成预聚物，或者采用柠檬酸（21）、1,8-辛二醇（22）、及1,2-丙二醇（23）制备成预聚物（20），将预聚物（20）溶解于无水乙醇（30）中，形成第二溶液（2），之后将第一溶液（1）与第二溶液（2）混合搅拌均匀，得到聚合物分散液晶与石墨烯纳米粒子（12）的混合体预聚物，将该混合体预聚物聚合数天后，制得PDLC薄膜。通过将聚合物分散液晶与石墨烯纳米粒子（12）结合，间接改变了聚合物基体的介电性，进而增强了聚合物分散液晶的反应速度、降低了聚合物分散液晶的驱动电压，且通过该制备方法所制得的PDLC薄膜的大小及厚度可调，应用更加便捷。
