제목 Enhanced, Parallel Orientation of Liquid Crystal on Phthalimide Substituted Polystyrene Film
초록 We synthesized phthalimide substituted polystyrene (PPH#) series, where # is the molar ratio of phthalimidoyl moiety, by substitution reaction to investigate liquid crystal (LC) orientation behaviors. The PPH# films exhibited good optical transparency in visible light region than polyimide (PI) film, commercialized in display industry. The LC cell made from pristine polystyrene film showed perpendicular orientation with respect to rubbing direction, whereas the LC cells fabricated with PPH# films exhibited parallel orientation when the substitution ratio was more than 20 mol%, respectively. Additionally, long-term stability of the LC cells made from PPH# series were remarkably enhanced as well as ultraviolet stability than those of LC cell made of polystyrene. Therefore, this study contributes to the technology of producing planar and parallel LC orientation on polystyrene derivatives and can be applied to next-generation display industry including flexible display.
