The Effect Of Radiation On Properties Of Polymers

The Effect of Radiation on Properties of Polymers examines the effects of radiation on plastics and elastomers. Polymers are required in products or parts for a range of cutting-edge applications that are exposed to radiation, in areas such as space, medicine, and radiation processing. This book focuses on the effects of radiation exposure within that environment, providing in-depth data coverage organized by category of polymer. Aspects such as radiation impact on mechanical and thermal properties, including glass transition and heat deflection temperatures, are described, demonstrating how changes in these properties affect the performance of plastic or elastomer parts. The effect of radiation on electrical properties is also included. Supporting introductory chapters explain the key concepts of radiation, including the physical, mechanical, and thermal properties of plastics and elastomers. This is a vital resource for plastics engineers, product designers, and R&D professionals, working on products or parts for radioactive environments, as well as engineers and scientists in the medical, nuclear, and radiation processing industries. The book also supports researchers and scientists in plastics engineering, polymer processing and properties, polymer and coatings chemistry, materials science, and radiation. Brings together highly valuable data on the effect of radiation on the properties of polymers and elastomers Enables the reader to compare properties and to select the best possible materials for specific applications Supported by detailed explanations and analysis, ensuring that the reader understands how to interpret and utilize the data

Atomic Radiation and Polymers examines the effects of radiation on polymer materials. The title deals with chemical changes that took place when polymers are exposed to radiation, and how these changes affect the physical properties of the polymers. The text first covers the interaction of radiation and matter, along with radiation sources and dosimetry. Next, the selection deals with the general properties of long chain polymers. The text also details the organic molecules and irradiated polymers. Chapters 22 to 24 tackle the radiation-induced changes in nuclear chain reaction, while Chapter 25 discusses the irradiation of polymers in solution where both direct and indirect effects occur. The next series of chapters details the theoretical aspects of reactions between the initial acts of ionization or excitation. The last two chapters cover the conductivity change at low radiation intensities, along with the data on radiation damage at very high intensities. The book will be of great interest to researchers and practitioners from the field of nuclear science and polymer technology.

Radiation Effects in Materials, Volume 1: Atomic Radiation and Polymers considers the theoretical and experimental studies on the association between polymers and atomic radiation. The use of radiation in polymer science constitutes a powerful tool for the quantitative study of macromolecules. This book consists of 31 chapters, and starts with a brief introduction to fundamentals of atomic radiation and polymer structure. The next chapters focus on some aspect of atomic radiation, including radiation units, radiation-matter interaction, and nuclear and electrical sources of radiation. A chapter presents the appropriate methods to study radiation chemistry and polymer. Considerable chapters are devoted to the molecular structure, chemistry, and reactions of polymers. This volume also describes some significant chemical changes of radiation. Other chapters explore the properties and reactions of various irradiated polymers. The remaining chapters deal with radiation protection effects in polymers, which are processes wherein small changes in chemical structure within a molecule or in its neighborhood can exert a disproportionately large influence on the overall chemical reactions. This book is of value to nuclear and solid state physicists, organic and polymer chemists, and nuclear engineers and radiobiologists.

​This book provides an introduction of how radiation is processed in polymeric materials, how materials properties are affected and how the resulting materials are analyzed. It covers synthesis, characterization, or modification of important materials, e.g. polycarbonates, polyamides and polysaccharides, using radiation. For example, a complete chapter is dedicated to the characterization of biodegradable polymers irradiated with low and heavy ions. This book will be beneficial to all polymer scientists in the development of new macromolecules and to all engineers using these materials in applications. It summarizes the fundamental knowledge and latest innovations in research fields from medicine to space.

This text examines the effect of radiation on polymers and the versatility of its industrial applications. By helping readers understand and solve problems associated with radiation processing of polymers, it serves as an important reference and fills a gap in the literature. Radiation processing can significantly improve important properties of polymers, however, there are still misconceptions about processing polymers by using ionizing radiation. This book explains the radiation processing of polymeric materials used in many industrial products including cars, airplanes, computers, and TVs. It even addresses emerging "green" issues like biomaterials and hydrogels.

Biomaterials repair, reinforce or replace damaged functional parts of the (human) body. All mechanical and biological interactions between an implant and the body occur across the interface, which has to correspond as nearly as possible to its particular function. Much of the progress in adapting polymer materials for use in a biological environment has been obtained through irradiation techniques. For this reason the most recent developments in four key areas are reviewed in this special volume: (1) the analysis of the topology and the elemental composition of a functional surface, (2) the chemical modification of the surface which results in highly pure, sterile and versatile surfaces, (3) the sterilisation of implantable devices via ionising radiation and its possible effects on the structural mechanical properties of polymers, and (4) the radiation effects on living cells and tissues which are of particular importance for radiation protection and radiotherapy.

The study of radiation effects has developed as a major field of materials science from the beginning, approximately 70 years ago. Its rapid development has been driven by two strong influences. The properties of the crystal defects and the materials containing them may then be studied. The types of radiation that can alter structural materials consist of neutrons, ions, electrons, gamma rays or other electromagnetic waves with different wavelengths. All of these forms of radiation have the capability to displace atoms/molecules from their lattice sites, which is the fundamental process that drives the changes in all materials. The effect of irradiation on materials is fixed in the initial event in which an energetic projectile strikes a target. The book is distributed in four sections: Ionic Materials; Biomaterials; Polymeric Materials and Metallic Materials.
