向列液晶分子在L—B膜上取向的测量及锚泊强度的估计

向列液晶分子在L—B膜上取向的测量及锚泊强度的估计 MEASUREMENTS OF THE ORIENTATIONS OF NEMATIC LIQUID CRYSTAL MOLECULES ON L-B FILMS AND ESTIMATION OF THE ANCHORING INTENSITY 张富良 Zhang Fuliang first-author 本文介绍一种新的测量表面倾角的方法,即通过测量样品的体双折射来测定指向矢在盒壁表面的取向。我们用此方法测量了向列液晶（5CB）分子在单分子层和双分子层山萮酸L-B膜上的取向,定性估计了锚泊强弱。 In this paper we present a new method determining surface tilt angle, i.e. determining the director orientations at the surface of the cell wall through the measurements of the bulk birefringence of the sample. Experim-entally the orientations of nematic liquid crystal（SCB）molecules on L-B films of monomolecular layer behenic acid and double-molecular layer behenic acid are measured with this method, and the anchoring status is qualitatively estimated. 向列液晶 山萮酸 指向矢取向 锚泊 体双折射 nematic liquid crystals behenic acid director orientation anchor bulk birefringence 1988-03-01 2021-04-01 3
