Processes in Photoreactive Polymers

Processes in Photoreactive Polymers

Their comprehensive model provided the explanation for the formation of
inhomogeneities in polymer distribution; however, it did not take into account the
mobility of the reactants and light intensity changes during the polymerization

The development of photosensitive materials in general and photoreactive polymers in particular is responsible for major advances in the information, imaging, and electronic industries. Computer parts manufacturing, information storage, and book and magazine publishing all depend on photoreactive polymer systems. The photo-and radiation-induced processes in polymers are also active areas of research. New information on the preparation and properties of com mercially available photosensitive systems is constantly being acquired. The recent demand for environmentally safe solvent-free and water-soluble materials also motivated changes in the composition of photopolymers and photoresists. The interest in holographic recording media for head-up displays, light scanners, and data recording stimulated development of reconfigurable and visible light sensitive materials. Photoconductive polymerizable coatings are being tested in electrostatic proofing and color printing. The list of available initiators, poly meric binders, and other coating ingredients is continually evolving to respond to the requirements of low component loss (low diffusivity) and the high rate of photochemical reactions.

Photochemical Processes in Polymer Chemistry-2 contains invited lectures presented at the Second IUPAC Symposium on Photochemical Processes in Polymer Chemistry held at Leuven, Belgium on June 2-4, 1976. This book contains 11 papers separated as chapters. Topics include energy transfer processes; photoinitiation of polymerization; solid-state polymerization mechanisms; photoinduced ionic polymerizations; and photoconductive polymers. This text also discusses energy transfer phenomena in high polymer systems; laser spectroscopical methods for the study of primary processes during the photodegradation; photooxidation of high polymers; and reaction selectivity and molecular association in photochemical reactions of nucleic acids and their constituents. New developments in photochromic polymers and related phenomena, as well as the design of photoreactive polymer systems for imaging processes are also explained.

Laser ablation describes the interaction of intense optical fields with matter, in which atoms are selectively driven off by thermal or nonthermal mechanisms. The field of laser ablation physics is advancing so rapidly that its principal results are seen only in specialized journals and conferences. This is the first book that combines the most recent results in this rapidly advancing field with authoritative treatment of laser ablation and its applications, including the physics of high-power laser-matter interaction. Many practical applications exist, ranging from inertial confinement fusion to propulsion of aerostats for pollution monitoring to laser ignition of hypersonic engines to laser cleaning nanoscale contaminants in high-volume computer hard drive manufacture to direct observation of the electronic or dissociative states in atoms and molecules, to studying the properties of materials during 200kbar shocks developed in 200fs. Selecting topics which are representative of such a broad field is difficult. Laser Ablation and its Applications emphasizes the wide range of these topics rather than - as is so often the case in advanced science – focusing on one specialty or discipline. The book is divided into four sections: theory and modeling, ultrafast interactions, material processing and laser-matter interaction in novel regimes. The latter range from MALDI to ICF, SNOM’s and femtosecond nanosurgery to laser space propulsion. The book arose from the SPIE series of High Power Laser Ablation Symposia which began in 1998. It is intended for a graduate course in laser interactions with plasmas and materials, but it should be accessible to anyone with a graduate degree in physics or engineering. It is also intended as a major reference work to familiarize scientists just entering the field with laser ablation and its applications.

Soft matter (polymers, colloids, surfactants and liquid crystals) are an important class of materials in modern technology. They also form the basis of many future technologies, for example in medical and environmental applications. Soft matter shows complex behaviour between fluids and solids, and used to be a synonym of complex materials. Due to the developments of the past two decades, soft condensed matter can now be discussed on the same sound physical basis as solid condensed matter. The purpose of this book is to provide an overview of soft matter for undergraduate and graduate students in physics and materials science. The book provides an introduction to soft matter (what it is, and what are the characteristics of such materials), and also provides the reader with the physical basis for understanding and discussing such characteristics in more detail. Many basic concepts, which are required in advanced courses of condensed matter physics, such as coarse graining, scaling, phase separation, order-disorder transition, Brownian motion, and fluctuation-dissipation theorem, are explained in detail with various forms of soft matter used as examples.

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 materials Manipulation of liquid crystalline by external constraints Advances in liquid crystal display screen technology Physical and electromagnetic properties of elastomers and magnetic gels Computer simulations and theory of liquid crystal polymeric networks and elastomers Side-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-dimensional structure in the molecular order and capture it created a number of compelling application possibilities because it provided necessary control of the molecular order. This book advances the understanding of basic science behind these systems, accelerates some of the proposed applications to the marketplace, and hopes to inspire generations of scientists to think broadly about these exciting and useful materials.
