Liquid crystal displays were discovered in the 1960s, and today we continue to enjoy the benefits of that fundamental discovery and its translation into a wide variety of products. Like liquid crystals, polymers are unusual materials, and have similarly enjoyed a great deal of research attention because of their vast applications and uses and complex fundamental properties. The combination of liquid crystal and polymer properties produces a broad array of new effects—spanning from densely crosslinked, rigid polymer networks to weakly crosslinked elastomers—that are not simply manifestations of either native liquid crystals or polymers alone. Cross-Linked Liquid Crystalline Systems brings together liquid crystal and polymer systems and their variations. The field, much like traditional liquid crystals, is one of an interdisciplinary nature with a broad spectrum, from the very fundamental questions of nature to a myriad of practical uses. There seems to be no shortage of unusual properties and far-reaching applications in densely crossed-linked liquid crystal systems and liquid crystal elastomers. These systems provide a rich new avenue for both fundamental and applied research and continue to fascinate scientists and engineers. Specifically, this book covers: Cross-linked networks created from reactive mesogen materialsManipulation of liquid crystalline by external constraintsAdvances in liquid crystal display screen technologyPhysical and electromagnetic properties of elastomers and magnetic gelsComputer simulations and theory of liquid crystal polymeric networks and elastomersSide-on nematic liquid-crystalline elastomers for artificial muscle applications Liquid crystal display technology has driven much of the fundamental research in crosslinked liquid crystalline systems. The systems’ ability to enforce three-di

Liquid Crystal Sensors discusses novel applications of liquid crystals that lie beyond electrically driven optical switches and displays. The main focus is on recent progress in the area of sensors based on low molar mass and polymer liquid crystals. This area of research became "hot" in recent years since the possibilities for applications of liquid crystal sensors are growing in many areas, ranging from the detection of mechanical displacements to the detection of environmental pollutants and chemical agents.This book is well-suited for students, as well as scientists from different backgrounds. For students and researchers new to the field, it gives a thorough introduction. For experienced researchers it shows the latest breakthroughs and serves as an inspiration for solving problems or sparking new ideas.Key Features:Emphasizes how liquid crystals are extremely sensitive to external stimuli and therefore can be used for the construction of stimuli-responsive devices, such as sensors Includes the contributions of editors who are deeply involved in the field and author chapters on hot topics such as the sensitivity of liquid crystals to pollutants, UV light, and strainProvides an exclusive on LC sensors where having the data in one place will be very useful to the community Gives more information on sensors and broadens the scope by having a contributed volume rather than authored Combines recent data on advances in the area of liquid crystal sensors that includes many types of liquid crystal materials

Flexible Flat Panel DisplaysA complete treatment of the entire lifecycle of flexible flat panel displays, from raw material selection to commercializationIn the newly revised Second Edition of Flexible Flat Panel Displays, a distinguished team of researchers delivers a completely restructured and comprehensive treatment of the field of flexible flat panel displays. With material covering the end-to-end process that includes commercial and technical aspects of the technology, the editors have included contributions that introduce the business, marketing, entrepreneurship, and intellectual property content relevant to flexible flat panel displays.This edited volume contains a brand-new section on case studies using the Harvard Business School format that discusses current and emerging markets in flexible displays, such as an examination of the use of electronic ink and QD Vision in commercial devices.From raw material selection to device prototyping, manufacturing, and commercialization, each stage of the flexible display business is discussed in this insightful new edition. The book also includes: Thorough introductions to engineered films for display technology and liquid crystal optical coatings for flexible displaysComprehensive explorations of organic TFT foils, metallic nanowires, adhesives, and self-healing polymer substratesPractical discussions of flexible glass, AMOLEDs, cholesteric displays, and electronic paperIn-depth examinations of the encapsulation of flexible displays, flexible batteries, flexible flat panel photodetectors, and flexible touch screensPerfect for professionals working in the field of display technology with backgrounds in science and engineering, Flexible Flat Panel Displays is also an indispensable resource for professionals with marketing, sales, and technology backgrounds, as well as senior undergraduates and graduate students in engineering and materials science.
