ABSTRACT This contribution investigates the preparation of polymer-dispersed liquid crystal (PDLC) films based on meth(acrylate) monomers containing rigid structures. The current study specifically focuses on comparison of the monomers on the basis of meth(acrylate) side group, flexible/rigid structures and rigidity. We find that methacrylate monomers exhibit more preferable electro-optic properties than that of the acrylate monomers. Furthermore, through the systematic variation of rigidity, composition of the monomers and chain length of crosslinking agents, both the morphologies and electro-optic properties of these films are found to be adjustable. A composite film is demonstrated by employing moderately rigid monomer (tetrahydrofurfuryl methacrylate) with low driving voltage (21.0 V) and high contrast ratio (87.5). Therefore, the studies here provide a new approach to optimize the electro-optical properties of the PDLC films by introducing monomers with rigid structures.

含(甲基)丙烯酸酯单体和不同链长交联剂的刚性结构对聚合物分散液晶薄膜形貌和光电性能的影响

摘要 此贡献研究了基于含有刚性结构的甲基（丙烯酸酯）单体的聚合物分散液晶 (PDLC) 薄膜的制备。目前的研究特别侧重于基于甲基（丙烯酸酯）侧基、柔性/刚性结构和刚性的单体比较。我们发现甲基丙烯酸酯单体比丙烯酸酯单体表现出更优选的电光性能。此外，通过刚性、单体组成和交联剂链长的系统变化，发现这些薄膜的形态和电光性能都是可调的。通过使用具有低驱动电压 (21.0 V) 和高对比度 (87.5) 的中等刚性单体（甲基丙烯酸四氢糠酯）来证明复合膜。所以，
