- Abstract
- Blue phases (BPs) of liquid crystals are highly valued in electro-optics for their fast, polarization-independent response and the advantage of not requiring alignment layers. While BP lattices do not need to be aligned to substrates, doing so can improve their electro-optic performance. Traditionally, rubbed polyimide films have been the preferred method for inducing monodomains in BPs. This study, using polarized optical microscopy, explores various BP compositions with different nematic hosts, chiral dopant concentrations, and alignment layer combinations, including polyimide, surfactants, and obliquely evaporated SiOx. The results show that while rubbed polyimide is effective for many BP compositions, it is not always the optimal choice for inducing monodomains. The research highlights that inorganic alignment methods can be more effective for BP compositions consisting of specific nematic hosts.
