中文摘要：
采用离子沉积法在玻璃基板表面制备了十四烷基磺酸盐自组装膜，用带有该自组装膜的基板制成的液晶器件呈现出垂直畈向效果。通过自组装反应过程分析，认为自组装膜表面的纵向沟纹引起了液晶的垂直排列。实验发现，当自组装膜烷烃碳链长度大于11个C原子就可获得垂直取向。这种取向膜制作过程简单、热稳定性好，非常有望应用于多畴垂直取向模式的液晶显示器。
英文摘要：
A self-assembled film of n-tetradecyl sulfosalt was fabricated in aqueous solution. The nematic liquid crystals could be aligned vertically on the glass substrate with the self-assembled film. By analysis of the chemical reaction of film-forming, it indicated that ordered vertical topography induced homeotropic alignment. If the alkyl group length was larger than 11C, the self-assembled film would induce vertical alignment. This type of alignment film can be fabricated easily, and has good thermalstability. It has some potential to be used in multi-domain-vertical （MVA） display.
