摘要研究了液晶性和分子聚集态对光取向过程的影响。在有序膜的情况下，光取向受到限制，但是这种限制可以通过使用UV光的光化学预处理或通过入射维斯光的更高功率密度来克服。光学各向异性随间隔基长度或聚合物的有序化趋势而增加。
Abstract The dependence of the Photo-orientation process on the liquid crystallinity and the molecular aggregation is studied. In the case of ordered films the photo-orientation is restricted, but this restriction can be overcome by a photochemical pre-treatment using UV light or by higher power density of the incident Vis light. The optical anisotropy increases with spacer length or the ordering tendency of the polymers.
