Special Issue Information
Ferroelectric and ferromagnetic liquid crystals (FLC) are smart materials with numerous structural puzzles that may one day be applied to industry. They are extremely useful, because they have a several-orders-of-magnitude-higher response time than traditional liquid crystals used in displays. For example, the field sequential colour technique could be potentially used for the creation of the full colour displays based on FLC, in which an arbitrary colour could be obtained as a red-green-blue (RGB) average over the time in each pixel and not over the space of three sub-pixels. The FLC displays could therefore have better resolution, brightness, and colour gamuts.
Manipulation by FLC structures requires lower energy consumption. The structures of many ferroelectric and ferromagnetic phases are easily memorized. FLC materials can be multistable, and therefore the memorisable greyscale can also be organized on the level of a single pixel. As a result, high-resolution images can be memorized using FLC materials for an infinite period of time (until the new image is rewritten by the new energy pulse).
The staircases of intermediate phases observed in the temperature interval between ferroelectric and antiferroelectric liquid crystal phases provide a great field for new inventions. The non-trivial structural organization of complex FLC phases provides the existence of several switchable states at different values of electric field. The existence of two kinds of periodicity in the intermediate phases (one at nano-scale and another one at micro-scale) provides a correlation between the micro and nano-structures, and therefore the nano-world can be potentially visualized by FLC materials. This could be very important for sensing devices, for example.
Finally, the FLC materials are brilliant materials for investigation of the matter creation in general, because they have are highly organized but, at the same time, are fluids in nature. This combination of properties makes them very useful materials for the investigation of micro-droplets creation, coalescence, and collective behaviour. These processes are very important for oil-recovery, food production, and cosmetics. They are actively studied in the microgravity conditions, in particular, at the International Space Station.
The potential topics include, but, again, are not limited to, the following:
- Novel FLC Phases, Structure, and Phase Behaviour
- Design and Synthesis of FLC Materials
- Photonic, Electro-, and Photo-Responsive FLC Systems
- Theory and Simulations of FLC Systems
- Hybrid and Nanostructured FLC Systems
- Antiferroelectric, Intermediate, and Re-Entrant Phases
- Memory Effects in FLC Materials
- Confined FLC Systems and Defects
- Self-Assembling of FLC Materials
- Applications of Ferroelectric and Ferromagnetic Liquid Crystals
