高分子膜の表面形状と液晶分子配向特性 (II)

抄録

Liquid crystal(LC) molecular alignment on polymer surfaces with some microscopic morphology was studied. Experiments were carried out by pulling the substrate, which was previously prepared by SiO 60° oblique evaporation, out of the PVA aqueous solution. The state of LC alignment of directors and pretilts depended strongly on the concentration of PVA, the pull-up speeds and Pull-up directions related to the direction of oblique evaporation. Then, by controlling these parameters, the areas of differently aligned LC textures could be clearly obtained on the same substrate.
