摘　　要：在直流电场下,将柔性氧化铟锡聚酯(ITO-PET)膜浸于丙烯酸水溶液中进行电聚合,从而在柔性膜表面实现聚合物的凹凸结构。文章用偏光显微镜研究了不同聚合物浓度稳定的胆甾相液晶形成的聚合物网络的织构和形貌,并对其反射光谱及阈值电压进行了测试,分析得出了表面凹凸结构对双稳态胆甾相液晶显示特性的影响。The ITO-PET films were immerged in acrylic acid aqueous solution under the DC electric field,to form the concave convex structure in their surface.Bistable cholesteric liquid crystal displays which stabilized by different polymer net were obtained.The reflected spectrum and the threshold voltage of them were tested and analyzed.One found the influence of the concave convex structure formed by this way to the electrooptical characteristics.
