ABSTRACT In this paper, by utilising the photoinitiated cationic polymerisation of liquid crystalline epoxide in LC solvents, the epoxy-based polymer stabilised liquid crystals (EPSLCs) were fabricated. The effects of the liquid crystalline epoxide content, UV intensity, polymerisation temperature, and initiator content on the network morphology of liquid crystalline epoxy polymers (LCEPs) and electro-optical characterisations of EPSLC samples were studied. The results suggested that the preparation conditions had a dominant effect on the morphology of the LCEP and the void size in the EPSLC sample. The increase of liquid crystalline epoxide content, UV intensity, and initiator content induced that the density of LCEP network became larger and the void size decreased, which resulted in that the stabilising effect from the LCEP network on the mesogenic solvent molecules was strengthened. Conversely, the increase of polymerisation temperature induced that the stabilising effect from the LCEP network on the LC molecules was weakened. Graphical abstract

环氧基聚合物稳定液晶的网络形态和光电特性

摘要在本文中，通过利用液晶环氧化物在液晶溶剂中的光引发阳离子聚合，制备了环氧基聚合物稳定液晶（EPSLCs）。研究了液晶环氧化物含量、紫外线强度、聚合温度和引发剂含量对液晶环氧聚合物 (LCEP) 网络形态和 EPSLC 样品光电特性的影响。结果表明，制备条件对 LCEP 的形态和 EPSLC 样品中的空隙尺寸有主要影响。液晶环氧化物含量、UV强度和引发剂含量的增加导致LCEP网络密度变大，空隙尺寸减小，这导致 LCEP 网络对介晶溶剂分子的稳定作用得到加强。相反，聚合温度的升高导致 LCEP 网络对 LC 分子的稳定作用减弱。图形概要
