This book provides a didactic derivation of the main theories of thermotropic and lyotropic liquid crystals, revealing the common molecular-theoretic framework that underpins both theories. This unified context will help young researchers in coming to grips with the basics of the simplest of liquid crystals, being uniaxial nematic liquid crystals, easing them into the intricacies of more complex forms of such materials irrespective of whether they are thermotropic or lyotropic. The coverage provides a theoretical understanding of the phase behaviour, that is, what drives molecules and particles to spontaneously align themselves, as well as an appreciation of the role of entropy, energy and so on. The focus here is on the main theories for the isotropic-nematic transition, being the Maier-Saupe and the Onsager theories, and how they are derived from a common description, known as (classical) density functional theory (DFT). This book will be a valuable resource for senior undergraduate and graduate students, and experimentalists and engineers who feel intimidated by more formal or rigorous theoretical accounts and textbooks. Exercises at the end of each chapter help the reader to apply the basic concepts also to other types of liquid crystal, in particular the smectic liquid crystal.

Über Autor(innen)

Paul van der Schoot
is a soft matter theorist in the research group Theory of Polymers and Soft Matter at the Eindhoven University of Technology. Since 2009 he is (part-time) Lorentz professor of Theoretical Physics at the Institute for Theoretical Physics of Utrecht University. Van der Schoot is working on the boundary between physics, chemistry, biology and nanoscience. His research includes the application of statistical mechanical theory to problems in soft biological matter and in nanoscience and technology, and the description and interpretation of experiments in these fields. Application areas are, among others, synthetic and natural supramolecular assemblies, liquid crystals, proteins, polymers and colloidal particles. Although predominantly focused on theory development, his research has led to three granted patents. Van der Schoot has been active in the field of theoretical virus physics for over ten years. He has, based on experimental data, developed formal models describing the design principles and self-assembly behaviour of virus proteins.
