## Abstract A series of 2βnaphthoxymethylβsubstituted polystyrenes (P2NAP) were prepared by the reaction of poly(chloromethylstyrene) with different amounts of 2βnaphthol to investigate the liquidβcrystal (LC) alignment properties of these polymer films. P2NAP with only 2βnaphthoxymethyl side group
We report here uniform and defect-free homeotropic alignment of nematic liquid crystal having negative dielectric anisotropy (ΞΞ΅<0) on cleaned substrates, which can be changed to bright state (homogeneous alignment) by applying an electric field. However, non-uniformity in the bright state would not
