中文摘要：
制备了不同单体浓度的聚合物稳定铁电液晶器件，测试了震动实验和热稳定实验前后样品的排列织构、电光特性和对此度．用原子力显微镜研究了各样品的聚合物形貌，表明在器件内部形成了沿摩擦方向延伸的聚合物网络，并且随着单体含量的增加聚合物网络更加致密．由于聚合物网络体锚定的引入，使得铁电液晶分子在外力和温度场下的运动受到限制，聚合物体锚定的增强使聚合物稳定铁电液晶的稳定性也逐渐提高．实验结果表明，单体含量为4％时，聚合物稳定铁电液晶的抗震性和热稳定性良好，电光曲线为无阈值“V”字型，对比度达150：1．
英文摘要：
To investigate the effect of the monomer concentration on the stability of polymer-stabilized ferroelectric liquid crystal. Polymer-stabilized ferroelectric liquid crystal devices were fabricated with 1wt%, 2wt%,4wt% monomer. The alignment structure ,electro-optic properties and contrast ratio were analyzed before and after mechanical shock test and thermal shock test . The AFM（atomic force microscope） study shows the difference in morphology of the polymer fibrils. It is indicated that the polymer-net parallels the rubbing direction and the polymer-net is dense with the increasing of monomer and the stability of ferroelectric liquid crystal is enhanced. Because of anchoring induced by polymer-net the ferroelectric liquid crystal is restricted when the mechanical and thermal shock occur. The stability of ferroelectric liquid crystal devices are enhanced , when the anchoring of polymer-net are increased. The results show that Polymer-stabilized ferroelectric liquid crystal devices with 4wt% monomer has good mechanical and thermal shock tolerance, it exhibits V-shaped electro-optic performance with a high contrast ratio of 150 ： 1.
