“…In our simple model, in the ferroelectric liquid crystal suspension, the dependence of the angular distortion on the electric field is similar to that in the pure system with effective dielectric function anisotropy given by voltage [6]. We shall present elsewhere a more complete general effective medium theory for ferroelectric liquid crystal suspension.…”

“…Such systems have been fabricated by Reznikov et al [6], who have shown that at low concentrations, at least in some cases, these submicron colloids appear similar to a pure liquid crystal. In particular, the colloidal particles do not scatter light in the manner that we might expect, and are therefore invisible.…”

A key liquid crystalline property for electro-optic applications is the Frederiks threshold electric field. There has been recent experimental interest in liquid crystal-based colloidal suspensions in which the colloidal nanoparticles both possess a permanent electric polarization and provide strong director anchoring on the particle surface. Such suspensions are sometimes known as Filled Liquid Crystals. Our calculations suggest, in qualitative agreement with experiment, that filling the nematic liquid crystal with ferroelectric nanoparticles can significantly decrease the electric Frederiks transition threshold field.

“…carbon nanotubes, silica microbeads, nanoparticles and various collides exhibit remarkable new physical phenomena. Experiments have shown that nanoparticles and ferroelectric nanoparticles can greatly enhance the physical properties of nematic and smectic liquid crystals [1][2][3][4][5][6][7][8][9][10][11].…”

INTRODUCTIONFor many years the science of liquid crystals mostly served the needs of liquid crystal display (LCD) industry; vast majority of funds and human resources were directed to development of numerous LCD modes in nematic liquid crystals (LCs). It was the needs of LCD industry that initiated rapid development of surface LC science, deep studies of correlation between the molecular structures and macroscopic properties of nematic LCs. Studies of more complicated LCs phases and composite LC materials to a large extent have also been initiated by numerous attempts to propose competitive alternative to the traditional nematic LCDs (e.g. PDLCs, bistable LCDs, ferroelectric LCDs). By the beginning of the last decade, the LCD industry has reached such a high level that its further progress has become determined mainly by development of the technology of non-LC components (for example, by fabrication of gigantic highquality glass substrates for the last generation LCDs). This initiated some kind of rebooting of the scientific and mercantile interests of the LC scientific community. There are many sectors of hi-tech industry where LCs have great potentials, such as biotech, telecommunication, and optical processing. The new applications require new materials, sometimes with rather exotic properties, and new technologies. For example, LC materials for telecommunications usually require LCs with strong birefringence but low refractive index, adaptive LC optics needs materials with huge birefringence and low viscosity. Many promising applications of LC for terahertz region are suppressed by a strong absorption of LCs in this region; biotech needs replacement of thermotropic LCs to water-based lyotropic LCs. Tiny and precise patterning of LC alignment over the boundary surfaces becomes crucial for developing new optical elements. All of these new industry needs changed the priority points of LCs science; a number of LCD-related publications steadily decrease in expense of publications on application of LCs in photonics, optical processing, biosensors, and magneto-optics.One of the directions of the development of the modern LCs science is design and study of numerous LC composite materials. Long-distance orientation interaction in mesophase leads to extremely strong influence of a dispersed material on the mesogenic properties of the LC and vice versa; the LC matrix can effectively arrange the positional and translational ordering of the inclusions in the matrix. Therefore, combination of the orientational ordering and relative translation freedom in LCs with properties of the dispersed materials allows scientists to give unique properties to the composite, which are not inherent to its components. In order to obtain synergetic properties, part of the dispersion material in a LC matrix should not be high. Apparently, Brochard and de Gennes [1] first suggested that doping of a nematic LC with elongated submicron ferromagnetic particles in very low volume fraction (f n 10 À3 ) should result in drastic increase of the LC ...
