Nematic liquid crystals possess a degree of orientational order of their constituent molecules (or particles) along a direction termed the director (𝑛 ̂) and are widely exploited in display technology {ref}. It had long been considered that nematic phases, even when comprised of extremely polar molecules, do not show a preference for bulk polar order; the molecular electric dipole vectors have an equal probability of orientation parallel or antiparallel with the director (i.e. 𝑛 ̂= -𝑛 ̂ ,Fig ). A nematic phase with polar ordering would also be ferroelectric; having the vast majority of its constituent electric dipole moments oriented along a single direction (-𝑛 ̂ ≠ -𝑛 ̂, Fig ). In 2017 Mandle et al. and Nishikawa et al. simultaneously and independently reported highly polar liquid crystalline materials that exhibited multiple nematic phases. The lower temperature nematic phase is now understood to be polar and is termed the ferroelectric nematic (NF) phase. The NF phase is of special scientific interest as the presence of polar order in a fluid system coupled with a strong linear electrooptical response and large polar domains . The NF phase may also be aligned using existing alignment techniques originally developed for conventional nematics , and potential applications are beginning to emerge e.g. electrostatic actuators.
