Description

超支化聚芳醚酮及其制备方法与应用、 薄膜晶体管液晶显示器的基板 技术领域
本公开涉及一种超支化聚芳醚酮及其制备方法与应用、 薄膜晶体管液晶 显示器的基板， 尤其涉及羟基封端超支化聚芳醚酮和腈基封端的超支化聚芳 醚酮及其制备方法与应用。 背景技术
液晶显示要求液晶分子在电场作用下显示图形时必须按照一定方向取 向。 能使液晶分子有序排列的是涂覆在液晶盒内表面的取向膜， 形成这种膜 的材料就是液晶取向膜。 现在工业生产上用作液晶取向膜的材料都是高分子 聚合物材料， 且绝大多数都是线性聚合物材料， 线性高分子聚合物在分子量 过大后会存在溶解性的问题， 同时为了锚定液晶分子需要在线性分子主链上 尽可能多的引入功能基团， 从而导致合成难度和成本较高。 为了改善聚酰亚 胺类取向膜材料的溶解性问题使用了前驱体聚酰胺酸材料， 但聚酰胺酸的保 存和使用都受时间和环境的影响很大,很大程度上制约了其实际应用的范围。 发明内容
本公开的一个目的是提供一种溶解性能良好， 成膜性好， 与液晶分子之 间的作用力增强的超支化聚芳醚酮。
本公开的一个方面所提供了一种超支化聚芳醚酮， 包含数均分子量 27500 ~ 45000、 分子量分布 1.45 ~ 1.84的下述通式化合物：
其中， R为 -OH或
Figure imgf000003_0001
。
本公开的另一个目的是提供一种制备超支化聚芳醚酮的方法。
本公开的另一个方面所提供了一种制备超支化聚芳醚酮的方法， 包括如 下步骤：
使 2,4 ',6-三氟-二苯酮与对苯二酚发生缩聚反应生成羟基封端超支化聚芳 醚酮； 所述 2,4',6-三氟 -二苯酮与所述对苯二酚的摩尔比 1 : ( 2.1-2.25 )。
例如本公开的超支化聚芳醚酮的方法， 还可以包括所述羟基封端超支化 聚芳醚酮与 4-硝基邻苯二腈反应生成腈基封端的超支化聚芳醚酮。
例如，所述 2,4',6-三氟 -二苯酮与所述对苯二酚在 140-150°C成盐 2-2.5小 时， 升温到 170-220 °C反应 6-8小时。
例如，所述 2,4',6-三氟 -二苯酮与所述对苯二酚在无水碳酸钾和 N-曱基吡 咯烷酮存在的条件下进行反应。
例如， 所述羟基封端超支化聚芳醚酮与所述 4-硝基邻苯二腈在无水碳酸 钾和 N, N-二曱基曱酰胺存在的条件下进行反应。
本公开的再一个方面还涉及上述的超支化聚芳醚酮在制备液晶取向膜中 的应用。
本公开的又一个目的是提供一种薄膜晶体管液晶显示器（TFT-LCD ) 的 基板。
本公开所提供的 TFT-LCD 的基板， 包括液晶取向膜， 该液晶取向膜包 括上述的超支化聚芳醚酮。
超支化聚合物（hyper-branched )可以简单的描述为具有高度支化结构的 聚合物， 它既与支化聚合物不同， 也与树形分子有别。正是这样独特的结构， 使其具有不同于线形聚合物的分子运动， 表现出许多线形聚合物所不具有的 特殊性能。 本公开的超支化聚芳醚酮， 由于在超支化结构中引入叛基六元环 结构， 而引入更多与液晶分子产生相互作用的基团， 可以更好的提供液晶分 子与液晶取向膜之间的作用力。 本公开的超支化聚芳醚酮溶解性能良好， 成 膜性好。
同时， 羟基封端的超支化聚芳醚酮还可以进一步功能化引入腈基等与液 晶分子相似的结构， 增强对液晶分子的作用力。 附图说明
