摘要
通过羟基聚酰亚胺与肉桂酸的接枝反应合成了具有光敏性的聚酰亚胺 ,并且通过红外、核磁确定了光敏性聚酰亚胺的结构。将合成的聚酰亚胺作为液晶取向层用在液晶显示器件中 ,证明其有良好的热稳定性。
A new photo-sensitive polyimide was synthesized through the hydroxyl-containing polyimide OPDA-BAPAF grafted with cinnamoyl group.The structure of the synthesized polyimide was characterized by IR and NMR,and was used as alignment layer in liquid crystal displays.It is proved that the alignment layer has good thermal-stability.
