基于LB技术的液晶分子定向研究

RESEARCH ON LIQUID CRYSTAL ALIGNMENT BY LB FILM TECHNIQUE

液晶分子定向不仅具有重要的实用价值,而且也是一个非常重要的理论问题。本文综述LB膜诱导液晶分子垂面、沿面、倾斜排列和液晶在LB膜上锚定转变等方面的研究进展。

Liquid crystal alignment is not only of great importance for industrial applications, but also a crucial problem from a scientific point of view. In recent years, the employment of the Langmuir-Blodgett (LB) film technique to align liqiud crystals has attracted great attention. In this paper, the hemeotropic alignment, the homogeneous alignment and the tilted alignment of liquid crystals induced by LB films are reviewed along with the recent advancement of anchoring transition of liquid crystals on LB films.
