本文提出了一种压敏聚合物分散液晶（PDCLC）器件，该器件通过紫外光聚合诱导相分离的方法将液晶（ChLC）封装在聚合物网络中。研究了丙烯酸酯单体浓度和官能度对PDCLC网络形貌和器件电光性能的影响。结果表明，随着ChLC液滴尺寸的增加，压敏器件的电光特性（包括反射率和对比度）得到改善。系统中适当的网络密度限制了ChLC的流量，并允许在设备上绘制高分辨率线。此外，还研究了器件从焦锥态到平面态的临界压力切换。该器件在柔性显示器件、光学传感器等领域具有广阔的应用前景。
We present a pressure-sensitive polymer dispersed cholesteric liquid crystal (PDCLC) device, in which a cholesteric liquid crystal (ChLC) is encapsulated by a polymer network via an ultraviolet photopolymerization induced phase separation method. The effects of the acrylate monomer concentration and functionality on the network morphology, and the electro-optic behaviour of the PDCLC device were studied. The results demonstrated that the electro-optic properties, including reflectivity and the contrast ratio of the pressure-sensitive device, were improved as the ChLC droplet size increased. An appropriate network density in the system limited the flow of the ChLC and allowed high-resolution lines to be drawn on the device. Additionally, the critical pressure switching of the device from a focal conic state to a planar state was investigated. The device developed in this study has promising applications in many fields such as flexible display devices and optical sensors.
