This is the first book to provide an in-depth presentation of photosensitive polyimides for electronic and photonic applications. The authors are leading specialists in this field from Japan, Europe and the U.S.
From the Preface
Aromatic polyimides were developed originally as thermostable flexible polymer films for space applications. Now polyimides have found widespread use in the manufacture of electronic devices and have been employed in increasingly diverse areas of electronics and information technology. In addition to their excellent thermal stability and high processability, a wide range of chemical and physical properties provided by molecular engineering makes polyimides highly versatile in the electronics and information industries.
Lithography of polyimides is an inevitable process in using polyimides for microelectronic fields, and hence increasing research has been devoted to developing photosensitive polyimides, which make it unnecessary to use photoresists for patterning polyimides and diminishing markedly the number of steps in fabrication of various electronic devices.
In addition, the development of technology of photosensitive polyimides is expected to play a great role in manufacturing photonic devices in the near future, when the design and control of hyper fine structures . . . including higher thermal stability and better processability would be essential.

Polymer films now play an essential and growing role in sensors. Recent advances in polymer science and film preparation have made polymer films useful, practical and economical in a wide range of sensor designs and applications. Further, the continuing miniaturization of microelectronics favors the use of polymer thin films in sensors.
This new book is the first comprehensive presentation of this technology. It covers both scientific fundamentals and practical engineering aspects. Included is an extensive survey of all types of sensors and applications. The very detailed table of contents in the next pages provides full information on content. More than 200 schematics illustrate a wide variety of sensor structures and their function.

A comprehensive account of the physical / mechanical behaviour of polyurethanes (PUs) elastomers, films and blends of variable crystallinity. Aspects covered include the elasticity and inelasticity of amorphous to crystalline PUs, in relation to their sensitivity to chemical and physical structure. A study is made of how aspects of the constitutive responses of PUs vary with composition: the polyaddition procedure, the hard segment, soft segment and chain extender (diols and diamines) are varied systematically in a large number of systems of model and novel crosslinked andthermoplastic PUs. Results will be related to: microstructural changes, on the basis of evidence from x-ray scattering (SAXS and WAXS), and also dynamic mechanical analyses (DMA), differential scanning calorimetry (DSC) and IR dichroism. Inelastic effects will be investigated also by including quantitative correlations between the magnitude of the Mullins effect and the fractional energy dissipation by hysteresis under cyclic straining, giving common relations approached by all the materials studied. A major structural feature explored is the relationship between the nature of the hard segment (crystallising or not) and that of the soft segments. Crystallinity has been sometimes observed in the commercial PUs hard phase but this is usually limited to only a few percent for most hard segment structures when solidified from the melt. One particular diisocyanate, 4,4'-dibenzyl diisocyanate (DBDI) that, in the presence of suitable chain extenders ( diols or diamines), gives rise to significant degrees of crystallinity [i-iii] and this is included in the present work. Understanding the reaction pathways involved, in resolving the subtle morphological evolution at the nanometre level, and capturing mathematically the complex, large-deformation nonlinear viscoelastic mechanical behaviour are assumed to bring new important insights in the world basic research in polyurethanes and towards applied industrial research in this area.

Discovered in the twentieth century, carbon nanotubes (CNT) were an integral part of science and industry by the beginning of the twenty first century, revolutionizing chemistry, physics, and materials science. More recent advances in carbon nanotube production methods have resulted in a tremendous push to incorporate CNTs into polymer matrices. Although many advances have been made, two major obstacles continue unresolved: the enhancement of interfacial adhesion between CNTs and polymer matrix, and the improvement of dispersion of CNTs in polymers. Both substantial original contributors to the field, the authors present Carbon Nanotubes for Polymer Reinforcement, the first monograph on various conventional and innovative techniques to disperse and functionalize carbon nanotubes for polymer reinforcement, elegantly explaining the basic sciences and technologies involved in those processes. Topics covered include: Use of CNTs in fabricating novel polymer composites Principles and mechanisms behind CNT dispersion and functionalization Methods for the functionalization and dispersion of CNTs in polymer matrices Effects of CNTs on functional and mechanical properties of polymer composites Optimization of CNT/polymer nanocomposite fabrication Carbon Nanotubes for Polymer Reinforcement is a comprehensive treatment and critical review of the new class of polymer nanocomposites, and points to areas of future developments. Composites engineers, scientists, researchers, and students will find the basic knowledge and technical results contained herein informative and useful references for their work, whether for advanced research or for design and manufacture of such composites.

The explosion of plastic material development continues to generate a proliferation of conversion processes and variants of these methods. Unfortunately, most books on plastics conversion focus on a single process, such as injection molding, limiting their usefulness to readers without prior knowledge of the field. Few, if any, single-source texts adequately describe and compare each of the plastic conversion processes together. Plastic Conversion Processes: A Concise and Applied Guide addresses that need. It provides a basic overview of each of the seven major conversion processes, which account for the creation of more than 97 percent of all plastics products today. This detailed guide assembles and integrates the wealth of information scattered throughout various literature, to provide a basic yet complete illustration of plastic conversion processes. Learn Methods to Compare, Evaluate, and Select the Best Process for Your Product This book is unique in that it employs an all-encompassing approach, offering more than a mere overview of basic theory and application related to each major process. Chapters begin with a process-attribute table to serve as a quick guide, and then briefly describe a particular conversion process. To ensure comprehensive understanding of each method and how it works, sections include a short history and detailed explanation of the particular equipment, tooling, and materials used, as well as general piece part design guidelines and case studies gleaned from real-life experience. There is a plastic term for every letter of the alphabet, making it one of the most complex fields in science. A "quick reference" section at the end of the book includes an exhaustive collection of more than 350 terms, definitions, acronyms, and a key process characteristics comparison chart. Supplemented with photos, diagrams, and illustrations t

The purpose of this book is to present in a monographic and systematised form a review of all the literature devoted to polyurethane-based polymeric sorbents in separation chemistry. The primary types of sorbents dealt with are polyurethane foams and open-pore polyurethanes. The structure of the monograph follows this dichotomy. A book of this nature should stimulate thinking and incite its reader to consult the original literature. It will, however, not make such a consultation superfluous. A fair amount of the results described in this monograph constitute the main activity of investigation which took place in the authors laboratories during the past decade.

Functionalized Polysulfones: Synthesis, Characterization, and Applications focuses on polysulfones and their derivatives, which are widely used as functional materials in the biochemical, industrial, and medical fields due to their structural and physical characteristics, such as good optical properties, high thermal and chemical stability, mechanical strength, resistance to extreme pH values, and low creep. Because of their antimicrobial actions, solubility characteristics, water permeability, and separation, the functional groups, which modify the hydrophilicity of polysulfones, are of particular interest for biomedical applications. In addition, the functional groups are an intrinsic requirement for affinity, ion exchange, and other special membranes. In this book, the bioapplications of polysulfones are presented in two categories: blood-contacting devices (e.g., membranes for hemodialysis, hemodiafiltration, and hemofiltration) and cell- or tissue-contacting devices (e.g., bioreactors made by hollow-fiber membrane and nerve generation through polysulfone semipermeable hollow membrane). Surface wettability and hydrophilicity trends, as well as the morphological characteristics of modified polysulfones, are analyzed for semipermeable membrane purposes. Select chapters provide an introduction to chelating units on the modified polysulfone structure to obtain potential applications, such as surface coatings on metals and glasses, adhesives, high-temperature lubricants, electrical insulators, semiconductors, and the reduction of heavy-metal pollution in ecosystems. Featuring recent scientific information, Functionalized Polysulfones: Synthesis, Characterization, and Applications advances the basic knowledge of students and researchers working in the field of polymeric materials, including physicists, chemists, engineers, bioengineers, and biologists.
