含液晶(LC)的全息聚合物纳米复合材料由于其独特的电开关光学性质而引起了人们的极大关注。本文将三种类型的多面体低聚倍半硅氧烷(POSS)掺杂到全息聚合物纳米复合材料中，以调节其有序结构和电光性能。这些POSS掺杂剂是具有8个反应性双键的甲基丙烯酰基POSS、具有1个反应性双键的甲基丙烯异丁基POSS和具有非反应性基团的氨丙基异丁基POSS。有趣的是，甲基丙烯酰基POSS主要与构造区内的聚合物网络化学键合，这会由于有序结构的抑制而降低衍射效率和电光性能。相比之下，甲基丙烯异丁基POSS对全息聚合物纳米复合材料的衍射效率和电光性能的影响可以忽略不计，同时显著提高了全息聚合物纳米复合材料的热稳定性，尽管它在化学上也与构造区内的聚合物网络相连。显然，氨丙基异丁基POSS主要位于破坏区域，明显改善了全息聚合物纳米复合材料的电光性能和热稳定性。
Holographic polymer nanocomposites containing the liquid crystal (LC) have garnered a great deal of attention primarily because of their unique electric-switchable optical properties. Herein, three types of polyhedral oligomeric silsesquioxane (POSS) are doped into the holographic polymer nanocomposites to tune their ordered structure and electro-optical performance. These POSS dopants are methacryl POSS with eight reactive double bonds, methacrylisobutyl POSS with one reactive double bond, and aminopropylisobutyl POSS with nonreactive groups. Interestingly, methacryl POSS is primarily chemically bonded to the polymer network within the constructive regions, which deteriorates the diffraction efficiency and electro-optical performance due to the depressed ordered structures. In contrast, methacrylisobutyl POSS displays a negligible effect on the diffraction efficiency and electro-optical performance while significantly improving the thermostability of holographic polymer nanocomposites, although it is also chemically linked to the polymer network within the constructive regions. Distinctively, aminopropylisobutyl POSS mainly locates in the destructive regions and clearly improves the electro-optical performance and thermostability of holographic polymer nanocomposites.
