2C08 混合液晶を用いたポリ4ビニルピリジン配向膜のアンカリング特性(液晶物理・物性,口頭発表,2015年日本液晶学会討論会)

抄録

An easy axis of rubbed polymers with aromatic side-chains depends on liquid crystal (LC) materials. MBBA and some LCs which aligns parallel to the rubbing direction (perpendicular to the slow axis) and other LCs aligning perpendicular to the rubbing direction are mixed. A relationship between alignment direction and mixture ratio of two LCs on the rubbed poly(4-vinyl pyridine) are investigated. An anchoring strength is also measured as a function of the mixture ratio. It is suggested that LC having a polar group is preferentially adsorb to alignment film.
