The primary goal of this program was to develop a promising new technique for the electrical monitoring of polymerizations based on a device called the charge-flow transistor, and its related device, the floating-gate charge-flow transistor. The program was directed toward the development of the instrumentation capabilities of the device and toward the research use of the method for the study of selected polymer systems.
A new technique for the electrical monitoring of polymerization reactions such as resin cure is described. The technique is based on the charge-flow transistor, which resembles a conventional MOSFET, but with a portion of the metal gate replaced by the resin under study. Electrical signals obtained from several resins undergoing cure are presented, along with an electrical circuit model that can account for the principal features of these signals. The dramatic change in signal shape during cure can be related to corresponding changes in both the real and imaginary parts of the dielectric constant. (Author).
This book covers properties, processing, and applications of conducting polymers. It discusses properties and characterization, including photophysics and transport. It then moves to processing and morphology of conducting polymers, covering such topics as printing, thermal processing, morphology evolution, conducting polymer composites, thin films
In the last 10 years there have been major advances in fundamental understanding and applications and a vast portfolio of new polymer structures with unique and tailored properties was developed. Work moved from a chemical repeat unit structure to one more based on structural control, new polymerization methodologies, properties, processing, and applications. The 4th Edition takes this into account and will be completely rewritten and reorganized, focusing on spin coating, spray coating, blade/slot die coating, layer-by-layer assembly, and fiber spinning methods; property characterizations of redox, interfacial, electrical, and optical phenomena; and commercial applications.
viii The danger is that the result so obtained may be an experimental artifact. Another approach is to examine in as much detail as possible the principles underlying the operation of a new device. This may not lead to a new sensor immediately, but those developed along these lines tend to be more reliable. The accent in this book is therefore on the principles behind the operation ("the trade") rather than on a description of applications ("the tricks of the trade") of individual sensors. In this respect it is written for students at both graduate and upper undergraduate levels. Approximately one semester's worth of material is presented. The book may also be useful for scientists and engineers involved in the development of new types of chemical sensors or for those who discover that "somebody else's sensor just does not work as it should" and wish to know why. The book is divided into five sections dealing with the four principal modes of transduction: thermal, mass, electrochemical, and optical, as well as a general introduction common to the four types. I have included five appendixes, which are intended as a quick reference for readers who may not possess sufficient background in some areas covered in the main text. I have run out of symbols in both the Latin and Greek alphabets. In order to avoid confusion and ambiguity I have confined the use of a set of symbols to each chapter and provided glossaries at the end of each chapter.
Hybrid Nanofillers for Polymer Reinforcement: Synthesis, Assembly, Characterization, and Applications provides a targeted approach to hybrid nanostructures, enabling the development of these advanced nanomaterials for specific applications. The book begins by reviewing the status of hybrid nanostructures, their current applications, and future opportunities. This is followed by chapters examining synthesis and characterization techniques, as well as interactions within nanohybrid systems. The second part of the book provides detailed chapters each highlighting a particular application area and discussing the preparation of various hybrid nano systems that can potentially be utilized in that area. The last chapters turn towards notable state-of-the-art hybrid nanomaterials and their properties and applications. This book is a valuable resource for researchers and advanced students across polymer science, nanotechnology, rubber technology, chemistry, sustainable materials, and materials engineering, as well as scientists, engineers, and R&D professionals with an interest in hybrid nanostructures or advanced nanomaterials for a industrial application. Provides synthesis methods, characterization techniques, and structure-property analysis for hybrid nanostructures Offers in-depth coverage that focuses on specific applications across energy storage, environment, automotive, aerospace, construction and biomedicine Includes the latest novel areas, such as elastomeric hybrid nano systems, hybrid ceramic polymer nanocomposites, and self-assembled structures
