Liquid crystals / S. Chandrasekhar

Public ISBD Titre : Liquid crystals Type de document : texte imprimé Auteurs : S. Chandrasekhar, Éditeur scientifique Editeur : Cambridge : Cambridge University Press Année de publication : 1992 Importance : 460 p. ISBN/ISSN/EAN : 978-0-521-42741-8 Langues : Anglais (eng) Catégories : Matériaux Tags : LIQUID CRYSTALS Index. décimale : B-G Résumé : "This is a new and greatly revised edition of Professor Chandrasekhar s classic book Liquid Crystals, first published in 1977. The subject of liquid crystals has grown into an exciting interdisciplinary research field with important practical applications. This book presents a systematic and self-contained treatment of the physics of the different types of thermotropic liquid crystals - the three classical types, nematic, cholesteric and smectic, and the newly discovered discotic type. Included is a description of the structures of these four main types and their polymorphic modifications, their thermodynamical, optical and mechanical properties and their behaviour under external fields. The basic principles underlying the major applications of liquid crystals in display technology and in thermography are also discussed. This book will be of great value to advanced students and researchers in condensed matter physics, chemical physics, materials science and technology with an interest in the physics, chemistry and applications of liquid crystals."

Thermotropic and lyotropic liquid crystals for the formation of zinc oxide nanohybrids / Sarmenio Saliba  

Public ISBD Titre : Thermotropic and lyotropic liquid crystals for the formation of zinc oxide nanohybrids Type de document : texte imprimé Auteurs : Sarmenio Saliba, Auteur ; Jean Daniel Marty, Directeur de thèse ; Kahn, Myrtil, Directeur de thèse Année de publication : 2011 Langues : Anglais (eng) Tags : NANOPARTICLES  LIQUID CRYSTALS  ANISOTROPIC GROWTH  ZINC OXIDE Résumé : "The work presented in this manuscript describes the incorporation of inorganic materials inside organic hosts. Our ambition was to successfully hybridize ZnO nanostructures with liquid crystals. This was achieved using different strategies, the choice of which depended on the desired properties of the final material. The objective was not only the synthesis and stabilization of the nanoparticles within, but also their organization in the LC medium. One approach was the functionalization of preformed ZnO spherical nanoparticles by thermotropic LC ligands. This was made possible using a ligand exchange mechanism. Due to a dynamic equilibrium at the surface of ZnO NPs, the mesogenic molecules could exhibit order at the molecular level, giving rise to novel LC/NP hybrids with enhanced LC properties. The organization of NPs could also be induced by the use of lyotropic liquid crystals. In this case, the NPs were not simply doped into a LC material, but synthesized directly inside the lyotropic phases. The synthesis of ZnO was therefore confined to domains of defined size and shape which can directly control the organization of the nanostructures growing within. Apart from organization of NPs, our constant objective was the fabrication of anisotropic nanoobjects via LC-assisted synthesis. Thermotropic liquid crystals consisting of novel low molecular weight branched mesogens have proved to be remarkable templates for anisotropic growth of ZnO nanocrystals. This anisotropic growth was also found to be influenced by the size of the LC molecules as observed with the fabrication of ZnO inside LC polymers. This work has shown the possibility of integrating inorganic material in LCs providing that the two constituents are able to sufficiently interact with one another."
