Effects of surface topology and highly anisotropic polymer LB films on liquid crystal alignment

Controlling molecular orientation, especially in liquid crystals, is of particular current interest for example in the development of display technology. Here it is shown, through studying various LCs (e.g. PCH5 or Oil red O, see figure) and orientation techniques, that the alignment of the polymer chains in the alignment layer plays the most important role in controlling the orientation of the liquid crystals. magnified image
