Genre: Science

Liquid crystals are partially ordered systems without a rigid, long-range structure. The study of these materials covers a wide area: chemical structure, physical properties and technical applications. Due to their dual nature -- anisotropic physical properties of solids and rheological behavior of liquids -- and easy response to externally applied electric, magnetic, optical and surface fields liquid crystals are of greatest potential for scientific and technological applications. The subject has come of age and has achieved the status of being a very exciting interdisciplinary field of scientific and industrial research. This book is an outgrowth of the enormous advances made during the last three decades in both our understanding of liquid crystals and our ability to use them in applications. It presents a systematic, self-contained and up-to-date overview of the structure and properties of liquid crystals. It will be of great value to graduates and research workers in condensed matter physics, chemical physics, biology, materials science, chemical and electrical engineering, and technology from a materials science and physics viewpoint of liquid crystals.

Introduction to Liquid Crystals

Genre: Science

This text relies on only introductory level physics and chemistry as the foundation for understanding liquid crystal science. Liquid crystals combine the material properties of solids with the flow properties of fluids. As such they have provided the foundation for a revolution in low- power, flat-panel display technology LCDs. In this book, the essential elements of liquid crystal science are introduced and explained from the perspectives of both the chemist and the physicist.; The text begins with an historical account of the discovery of liquid crystals and continues with a description of how different phases are generated and how different molecular architectures affect liquid crystalline properties. The rest of the book is concerned with understanding and explaining the properties of the various types of liquid crystals, and in the final part of the book, the technology of LCDs is discussed and illustrated.

Liquid crystals are a phase of matter critical both in many recent scientific developments in biology, chemistry, and physics and in applications such as computer displays, electronic books, and new thermometers. This fully illustrated book builds on basic scientific concepts from biology, chemistry, and physics to explore the full range of the broad and interdisciplinary field of liquid crystal science. After a brief introduction to liquid crystals, the text sketches the history of research into this phase of matter, beginning with its discovery.

The behavior of the various liquid crystalline phases is described in detail, with an emphasis on the electrical and optical properties so important for applications. Applications are then covered, with in-depth attention given to how liquid crystals are used in computer-screen displays. Chapters dealing with liquid crystalline phases formed in solutions, the liquid crystal phases of polymers, and the biological significance of liquid crystals explore the huge range of phenomena associated with liquid crystals--from new high-strength fibers to the frontiers of cell-membrane research. Finally, there is a chapter highlighting current theoretical knowledge about why liquid crystals exist and why they have the properties they do. In this second edition, many portions of the highly praised first edition have been thoroughly revised and expanded to incorporate the tremendous theoretical and applied research advances made over the last decade.

Genre: Technology & Engineering

The existence of liquid crystals has been known for nearly a centu ry; yet it is only in the last ten years that their unique optical, electri cal, electro-optic, and thermal properties have been exploited to any significant extent in such technological applications as digital d~ plays and thermography. Digital watches equipped with liquid-crys tal displays (LCD's) have recently made their debut in the electronic watch market, and the large-scale use of LCD's in a variety of other applications requiring reliable, low-power digital displays is immi nent. There is good reason to believe that liquid crystals will be the first electro-optic materials to find widespread commercial use. Apart from applications, liquid crystals are unique among the phases of matter. Lurking beneath their garish display of color and texture is a great complexity of physical and chemical interaction that is only now beginning to unfold in the face of a decade-old resurgence in all aspects of liquid~rystal research. RCA Laboratories has participated in this resurgence from its beginning in the early 1960's and at present maintains active liquid-crystal programs both in basic re search and in device engineering. In view of the widespread interest in liquid crystals at RCA Labo ratories, an in-house weekly seminar devoted to the subject of liquid crystals was organized in the fall of 1973. The resulting lectures were subsequently published in three issues of the RCA Review and, with the incorporation of much additional material, eventually grew into the present volume.
