Abstract

We have promoted the complex patterned orientation of liquid crystal on polyvinyl cinnamate (PVCi) substrates by a single-exposure technique using the photocuring process. The process involves the polymerization of the polymer simultaneously by optical and thermal means. The information restored in the form of homogeneous or homeotropic orientation of the liquid crystal is nonerasable and permanent.
