Liquid Crystal Alignment on Polymer Films: Changes of the Pretilt Angles Due to the Thermal Treatment of Polyalkylene Pyromellitimides

概要
- 論文の詳細を見る
Two polyimides have been cured at different temperatures and some samples further annealed at different temperatures after rubbing. It is found that the pretilt angles on these films increase with increasing curing temperature and/or increasing curing time. There is a further increase in the preiilt angle after annealing, but this effect is dependent on the structure of the polyimide as well as the pretreatment conditions of the sample. All these observations can be explained by considering the change in the alignment of the polyimide and thus the induced in-plane order of the liquid crystalline layer.
