聚合物LB膜定向铁电液晶的特性

利用新近合成的聚酰亚胺ＬＢ膜定向铁电液晶分子,通过原子力显微镜对经不同亚胺化温度处理的聚酰亚胺ＬＢ膜进行扫描探测,发现相应的ＬＢ膜具有不同的形貌结构,认为高温亚胺化的ＬＢ膜可以提高较高的势垒,这为铁电液晶双稳记忆性的出现提供了可能,而ＬＢ膜的超薄特性有利于开关过程中表面聚积电荷的中和与释放,保证了器件优良的双稳记忆性的最终获得以及微秒量级快速响应的实现。     

PREPARATION OF STRIPE-SHAPED DOMAIN STRUCTURE IN FERROELECTRIC LIQUID CRYSTAL AND THE FABRICATION OF SPATIAL LIGHT MODULATOR

The stripe-shaped domain (SSD) structure was prepared in the initial ferroelectric liquid crystal (FLC) alignment without the application of an external electric field, which was realized by the aligning layer modification through the doping of tin tetra-2, 4-dimethyl phenoxy phthalocyanine (SnPc) into the rubbed polyimide films. Atomic force microscopy was used to investigate the alignment films and the corresponding aligning ability was evaluated through the pre-tilt angle measurement. The memory capability and the contrast ratio of thus aligned SSFLC cells have been enhanced and improved with the appearance of the SSD structure. The electrically controlled 64×64 FLC spatial light modulator was fabricated using the improved ligning method, which proves valuable for the practical device fabrication.
