The study of polymers by electron microscopy (EM) needs special techniques, precautions and preparation methods, including ultramicrotomy. General characteristics of the different techniques of EM, including scanning force microscopy, are given in this hands-on book. The application of these techniques to the study of morphology and properties, particularly micromechanical properties, is described in detail. Examples from all classes of polymers are presented.

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.

With a focus on structure-property relationships, this book describes how polymer morphology affects properties and how scientists can modify them. The book covers structure development, theory, simulation, and processing; and discusses a broad range of techniques and methods. • Provides an up-to-date, comprehensive introduction to the principles and practices of polymer morphology • Illustrates major structure types, such as semicrystalline morphology, surface-induced polymer crystallization, phase separation, self-assembly, deformation, and surface topography • Covers a variety of polymers, such as homopolymers, block copolymers, polymer thin films, polymer blends, and polymer nanocomposites • Discusses a broad range of advanced and novel techniques and methods, like x-ray diffraction, thermal analysis, and electron microscopy and their applications in the morphology of polymer materials

A practical guide to the study and understanding of the structure of synthetic polymer materials using the complete range of microscopic techniques. The major part of the book is devoted to specimen preparation and applications. New applications and additional references provide a critical update.

Scope of the Book Synthetic and natural polymers exhibit a complex structural and morphological hierarchy on multiple length scales [1], which determines their performance. Thus, research aiming at visualizing structure and morphology using a multitude of microscopy techniques has received considerable attention since the early days of polymer science and technology. Various well-developed techniques such as optical microscopy and different forms of electron microscopy (Scanning Electron Micr- copy, SEM; Transmission Electron Microscopy, TEM; Environmental Scanning Electron Microscopy, ESEM) allow one to view polymeric structure at different levels of magni?cation. These classical techniques, and their applications to po- mers, are well documented in the literature [2, 3]. The invention of Scanning Tunneling Microscopy (STM) inspired the devel- ment of Atomic Force Microscopy (AFM) and other forms of scanning proximity microscopes in the late 1980s [4, 5]. AFM, unlike STM, can be used to image n- conducting specimens such as polymers. In addition, AFM imaging is feasible in liquids, which has several advantages. Using liquid imaging cells the forces between specimen and AFM probe are drastically reduced, thus sample damage is prevented. In addition, the use of water as imaging medium opened up new applications aiming at imaging, characterizing, and analyzing biologically important systems.

Synthetic polymers make excellent specimens for light microscopy. Despite this, the use of the technique, at least in its advanced forms, is not so widespread as might be expected. Although reliable and relevant data are difficult to find and quantify, it seems that in other fields of materials science and technology there is a greater readiness to tum to the microscope in research, in industrial problem solving, or for quality assessment and control. It also seems that the reasons for the present situation are partly historical, partly the result of the structure of the plastics and rubber industries, and partly the education and training background of senior staff who tend to be chemistry or engineering based. In neither field does light microscopy feature strongly in the basic training. The primary aim of this book is to provide some insight into the range oflight microscopy techniques applicable to polymeric specimens, and to highlight typical applications to commercial polymers and polymer products. Where appropriate, the optical techniques involved are discussed in some detail. However, it has not been the intention to produce a light microscopy textbook dealing with the principles and design of the basic instrument. Many such texts are available, and selected examples are cited in the reference list at the end of most chapters.

Crystalline or, more properly, semi-crystalline polymers continue to present major challenges and opportunities to scientists and technologists alike. On the one hand, scientific understanding of their structure and properties still lags behind that of other economically important, but less complicated materials. On the other hand, there remains very considerable potential for improving properties in systems designed for specific pur poses. Ways are only just being found of transferring inherent molecular properties (such as high modulus) to the macromolecular solid. Beyond these are many possibilities of manipulating the organization of chemical and physical textures towards desired ends. The chapters in this volume are reports, by wen-known and active researchers, on some of the important recent developments ofthese themes. Grubb begins with the fundamental and central problem of determining polymeric microstructure. Polymers sutTer by comparison with other materials in that it has not generany been possible to exploit the high resolution of the electron microscope to determine their microstructure in adequate detail. However, recently, ways have been found of studying representative lamellar textures in melt-crystallized polymers. When fully exploited these must add greatly to our detailed knowledge and provide a firmer fundamental base for future developments. Radiation damage bears the primary responsibility for restricting electron microscopy. In his chapter, Kener recounts how appreciation of this fact led him into a fascinating study of ever deeper aspects of radiation damage in polyethylene over two decades, often controversiany but invariably clarifying the basic understanding of an area now of increasing commercial importance.
