Various types of side‐chain liquid crystal polymers with ferroelectric, photoactive, thermochromic, hydrogen‐bonded, and ionized properties have been synthesized by many research groups, and their physicochemical properties and orientational behavior have been studied. These studies have established the relationship between the structure and the physicochemical properties. This chapter describes the design and synthesis of a conventional side‐chain liquid crystal polymer in which mesogenic side groups are attached to the polymer chains.

“…Doping of nematics with strongly polar ferroelectric NPs also leads to an increase of their dielectric constant and enhances the electro-optic response [7][8][9][10][11]. In nanocomposites based on side-chain liquid crystal polymers, the semiconductor quantum dots may positionally order in self-assembled periodic structures [12,13].…”

A molecular field theory and coarse grained computer simulations with dissipative particle dynamics have been used to study the spontaneous orientational ordering of anisotropic nanoparticles in the lamellae and hexagonal phases of diblock copolymers and the effect of nanoparticles on the phase behaviour of these systems. Both a molecular theory and computer simulations indicate that strongly anisotropic nanoparticles are ordered orientationally mainly in the boundary region between the domains, and the nematic order parameter possesses opposite signs in adjacent domains. The orientational order is induced by the boundary and by the interaction between nanoparticles and the monomer units in different domains. In simulations, sufficiently long and strongly selective nanoparticles order also inside the domains. Nematic order parameter and local concentration profiles of nanoparticles have been calculated numerically using the model of a nanoparticle with two interaction centres and also determined using the results of computer simulations. A number of phase diagrams have been obtained which illustrate the effect of nanoparticle selectivity and molar fraction of the stability ranges of various phases. Different morphologies have been identified by analysing the static structure factor and a phase diagram has been constructed in coordinates nanoparticle concentration -copolymer composition. Orientational ordering of even a small fraction of nanoparticles may result in a significant increase of the dielectric anisotropy of a polymer nanocomposite which is important for various applications.

“…In particular, doping of nematic liquid crystals (LCs) with various NPs affects many important properties of nematic materials, resulting, for examples, in an improvement of switching voltages and switching times of LC displays (see [1][2][3][4][5]). Also doping of nematics with ferroelectric NPs is known to enhance dielectric and optical anisotropy of nematic materials and to crease their electro-optic response [6,7] Metal NPs have been also used to increase the temperature range of LC blue phases [8] while a small admixture of semiconductor quantum dots in smectic LC-polymers may result in the positional ordering of nanosize particles [9,10].…”
