Liquid-crystalline order in polymer systems: Basic models

Author(s): Holyst, R and Oswald, P
Title: Liquid-crystalline order in polymer systems: Basic models
Abstract: The liquid crystalline (LC) order appears in a variety of polymer such as solutions of rod-like molecules (DNA, TMV), solutions semiflexible molecules (long fragments of DNA), block-copolymer main-chain and side-chain liquid crystalline polymer melts etc. LC phases have been observed in these systems: the most common the nematic, cholesteric, smectic or lamellar, hexagonal, and gyroid (in block copolymers) phases. We will discuss in detail of them and give their quantitative description in terms of order We will also present various theoretical models used to LC ordering in the systems. The models discussed in this paper are follows: Onsager model and its extension within the Density Theories (DFT), Khohlov-Semenov model for semiflexible Kratky-Porod model, combination of the Kratky-Porod model and model, self-consistent field theoretical model and finally Landau-Ginzburg models and their connection with the Edwards model polymer systems. We will also briefly discuss the elasticity of systems in the case of nematic ordering. We present in a manner the general ideas which are behind various models and give references to the papers which contain the technical details.
