Download or read book Ion Etching of Amorphous and Semicrystalline Fibers written by S. B. Warner and published by . This book was released on 1975 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion etching of amorphous and semicrystalline polymeric or graphite fibers produces structures which can be observed in either the transmission electron microscope or the scanning electron microscope. The structures so produced have previously been identified as resulting from the etching process (artifacts), or as representing characteristics of the material, or both. The artifacts can be eliminated or minimized by rotating the sample during irradiation, using a low angle of incidence, and ensuring that the temperature of the sample surface remains low. When such precautions are used, amorphous fibers and semicrystalline fibers which are not oriented remain featureless after ion etching. Oriented semicrystalline fibers, however, develop a striated structure which is oriented perpendicular to the stretch direction. These transverse structural features reflect characteristic features of drawn fibers; but the relation between these features and the lamellar spacing is unclear.

Download or read book Synthetic Fibres written by J E McIntyre and published by Elsevier. This book was released on 2004-10-29 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthetic fibres account for about half of all fibre usage, with applications in every field of fibre and textile technology. Although many classes of fibre based on synthetic polymers have been evaluated as potentially valuable commercial products, four of them - nylon, polyester, acrylic and polyolefin - dominate the market. These four account for approximately 98% by volume of synthetic fibre production, with polyester alone accounting for around 60%.Synthetic fibres: nylon, polyester, acrylic, polyolefin provides a brief history of the early evaluations that led to this situation, then looks in detail at the development and present status of each class in four substantial chapters. Synthesis of chemical intermediates, polymerisation methods, fibre spinning and orientation technology, texturing techniques, production of microfibres, and chemical variants, e.g. for modified dyeability, are considered in detail. This comprehensive and accessible book will appeal to textile technologists in industrial and academic research, chemical and synthetic fibre suppliers, and yarn and fabric manufacturers. - Comprehensive overview of four major fibres

Download or read book Nuclear Science Abstracts written by and published by . This book was released on 1975 with total page 900 pages. Available in PDF, EPUB and Kindle. Book excerpt: NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.

Download or read book Polymer Microscopy written by Linda C. Sawyer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern materials include a vast array of polymers and plastics which are found in applications such as housing, appliances, clothing and household textiles and automotive and aerospace industries. Thus research scientists, engineers and materials science graduate students need to be aware of the methods and techniques required to understand the structure-property relations of polymer materials. This book will review the field of the microscopy of polymers. There is a vast literature which describes the research results obtained by study of polymer materials using microscopy and other complementary analytical techniques and such studies are best left to journals on specific topics. The major objective of this text is to provide the basic microscopy techniques and specimen preparation methods applicable to polymers. The book will attempt to provide enough detail so that the methods described can be applied, and also to reference appropriate publications for the investigator interested in more detail. The selection of two authors for this text came from the desire for a comprehen sive review of polymer microscopy with emphasis on methods and techniques, rather than on research results. The synergism provided by two authors with widely varied backgrounds was thought to be important: one author (LCS) has an industrial focus and a background in chemistry whilst the other (DTG) has an academic environment and offers a background in polymer physics.

Download or read book Polymer Microscopy written by Linda Sawyer and published by Springer Science & Business Media. This book was released on 2008-12-24 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: This extensively updated and revised Third Edition is a comprehensive and practical guide to the study of the microstructure of polymers. It is the result of the authors' many years of academic and industrial experience. Introductory chapters deal with the basic concepts of both polymer morphology and processing and microscopy and imaging theory. The core of the book is more applied, with many examples of specimen preparation and image interpretation leading to materials characterization. Emerging techniques such as compositional mapping in which microscopy is combined with spectroscopy are considered. The book closes with a problem solving guide.
