A Study on the Molecular Orientation of Nematic Liquid Crystal Monolayers on the water Surface

네마틱 액정의 수면상 단분자막에서의 분자 배향 연구

In this study, we used both displacement-current method and BAM(Brewster-Angle Microscope) to study on the molecular orientation of monolayer on the water surface. The displacement-current method measured behaviors of molecules by current and BAM was shown to be sensitive to film anisotropy even when the molecules were not tilted as long as the unit cell was anisotropic. Every transition was visible with BAM technique, either as a dramatic change in decree of contrast or as a sudden alteration of the mosaic domain texture.
