Cross-Linked Liquid Crystalline Systems

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 effectsspanning from densely crosslinked, rigid polymer networks to weakly crosslinked elastomersthat 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.
