氢键组装PVA侧链液晶高分子材料的合成

Synthesis of Hydrogen-bond Assembling PVA Side Chain Type Liquid Crystal Polymer Materials

本文在对氢键组装PVA侧链液晶高分子材料的合成分析研究过程中,以异烟酸及硝基苯酚作为基础材料,构建液晶基元异烟酸,进而对PVA电子受体进行分析研究。异烟酸与硝基苯酚应用有相同的氮原子,借助氢键对PVA侧链液晶高分子材料特征进行了解。在对PVA侧链液晶高分子材料特征分析研究过程中,借助介晶基元异烟酸氢键组装方式,在热台偏光显微镜度对PVA侧链液晶高分子材料进行液晶行为分析。在分析研究之后认为,异烟酸在合成之后,氢键组装PVA侧链液晶高分子及硝基苯酚脂都呈现出液晶性能。

In the analysis and study process of hydrogen-bond assembling PVA side Chain type liquid crystal polymer synthesis, taking the isonicotinic acid and nitrophenol as the basic materials to build the mesogenic unit isonicotinic acida and then take analysis and study of PVA electron acceptor. The application of isonicotinic acid and nitrophenol has same nitrogen-atoms, in this paper, with the help of hydrogen bond to know the features of PVA side chain type liquid crystal polymer materials. In the process of analysis and study process of PVA side Chain type liquid crystal polymer materials, with the help of mesogenic unit isonicotinic acida hydrogen bond assembling method to take liquid crystalline behaviour of PVA side Chain type liquid crystal polymer materials by the thermal platform microscope. After the analysis and study, we think that after the isonicotinic acid synthesis, hydrogen-bond assembling PVA side Chain type liquid crystal polymer and nitrophenol perform the liquid crystal property.
