Polymer‐stabilized liquid crystal (PSLC) devices can realize fast switching between transparent and scattering state, and have been widely applied as smart windows and optical shutters. It has many advantages such as high transmittance, high haze value, fast response speed, and low driving voltage. The electro‐optical response of PSLC devices depends on the properties of the liquid crystal molecules and the influence of the polymer network on the motion of the liquid crystal molecules. In this paper, the effect of polymer network morphology on the performance of PSLC devices is systematically studied. By adding mono‐acrylate monomer into the liquid crystal di‐acrylate monomers, the polymer network became softer and sparser after photopolymerization. The threshold voltage and response time of PSLC devices decreased with increasing the mono‐acrylate monomer concentration, but changed to increase after the concentration exceeds 1.8 wt%. This study provides guidelines to optimize of PSLC based optical devices and windows.

聚合物网络拓扑结构对聚合物稳定液晶（PSLC）器件电光性能的影响

聚合物稳定的液晶（PSLC）器件可实现透明和散射状态之间的快速切换，并已被广泛用作智能窗和光学百叶窗。它具有许多优点，例如高透射率，高雾度值，快速响应速度和低驱动电压。PSLC器件的电光响应取决于液晶分子的特性以及聚合物网络对液晶分子运动的影响。本文系统地研究了聚合物网络形态对PSLC器件性能的影响。通过将单丙烯酸酯单体添加到液晶二丙烯酸酯单体中，光聚合后聚合物网络变得更柔软和稀疏。PSLC器件的阈值电压和响应时间随单丙烯酸酯单体浓度的增加而降低，但在浓度超过1.8 wt％时改变为增加。这项研究提供了优化基于PSLC的光学设备和窗户的指南。
