| 中文摘要 | an alignment study of a liquid crystalline copolyether tpp-7/11(5/5) thin films has been carried out in a 10 kv . cm(-1) electrostatic field parallel to the thin film surface normal. this copolyether possesses a negative dielectric anisotropy. the chain molecules are homogeneously aligned in the electric field and they form two-dimensionally ordered lamellae in a tilted columnar phase when the samples were cooled to room temperature. it is observed that the chain molecules are splayed to form bent lamellae and the chain direction is perpendicular to the tangential direction of the lamellar surfaces. these lamellae thus become replicas of the chain orientation, due to the flexoelectric effect and density fluctuation on the thin film free surface, disclinations having topological strength s = 1, c = pi /4 and defect walls form. these s = 1 disclinations possesses both left- and right-handednesses. discussion of the defect formations have been attempted. |
