摘　　要：实验研究了聚合物分散正性和负性向列相液晶的电场诱导定向聚合,给出样品实物照片和偏光显微镜照片。实验结果表明,样品在施加电场和不施加电场的不同区域具有明显区别,在制备聚合物分散液晶样品时施加电场有诱导定向聚合作用。实验结果对于研究聚合物边界条件对液晶微滴构型的影响,对于设计新型液晶显示器件具有一定的启示意义。The field induced stereo regular polymerization of polymer dispersed nematic liquid crystal both positive and negative dielectric character are experimentally studied,the picture in kind and polarizing microscope photograph of samples are given.The experiment results show that there are obvious distinguish with in different area of electric field applied or not,the electric field has the induced stereo regular polymerization action under the polymer dispersed liquid crystal sample preparation process.The experiment results are useful to understand the influence of polymer border condition to liquid crystal micro drop configuration,and are in a sense of gaining a good deal to design a new type liquid crystal display device.
