Abstract
Composite films of polystyrene/polyimide onto ITO glass prepared with disperse domain of polystyrene in the polyimide matrix align liquid crystals in multi-domain by single rubbing process. The size of the polystyrene domain was controlled by varying the rpm of spin coating and weight ratio of polystyrene in polyimide film. When the films were rubbed, polyimide forced liquid crystals to orient to a rubbing direction, while polystyrene forced to the perpendicular direction. After the rubbing process, multi-domain structured films aligned the liquid crystals with various directors.
