摘　　要：本文研究了液晶和聚酰亚胺分子在聚酰亚胺LB膜上的取向效果。聚酰亚胺链在LB膜中的取向程度低于强摩擦膜表面聚酰亚胺链的取向,这可能由于聚酰亚胺分子的结构线性不好所致。9或11层LB膜可以很好地排列液晶分子,但液晶在聚酰亚胺LB膜上的取向效果劣于强摩擦膜表面的情形。The orientational effect of liquid crystal and Polyimide molecules on the LB films was studied. The orientation degree of Polyimide chain in the LB films is less than that in the strong rubbing films. Thin result maybe due to bad linear structure of Polyimide. The 9 or 11 LB film layers may well align liquid crystals, but the orientation effect of liquid crystals on the Polyimide LB films is worse than that on the strong rubbing films.
