In this chapter, effects of total dose of gamma-ray irradiation on tracking failure of polymer materials are described. The results reveal that the tracking failure properties are greatly changed by gamma-ray irradiation.

    By the UV-irradiation the absorption coefficient x ofthe illuminated polymer material is strongly increased [7][9] due to the photochemical formation of absorption centers like double bondings C=C. In the context of cancer treatment, gold nanoparticles (AuNPs) are considered as very promising radiosensitizers. Here, well-defined polymer-grafted AuNPs were synthesized and studied under gamma irradiation to better understand the involved radiosensitizing mechanisms. First, various water-soluble and well-defined thiol-functionalized homopolymers and copolymers were obtained through atom.

      Ionizing radiation can induce some kinds of reactions, other than polymerization, such as dimerization, oligomerization, curing, and grafting. These reactions occur through a regular radical chain causing growth of polymer by three steps, namely, initiation, propagation, and termination. To understand ionizing radiation-induced polymerization, the water radiolysis must be taken into .   THE interaction of high-energy radiation with various forms of matter has been shown to produce a variety of chemical effects, depending upon the system. These effects fall into various classes Cited by:

Cross-linking is the new bond formation in polymer chains, i.e., intermolecular bond formation (Fig. ).A long time ago, polyethylene was the first polymer that was cross-linked with irradiation [39].Cross-linking is a very important parameter that affects with the polymer irradiation as it can generally improve the thermal and mechanical characteristics and environmental and chemical.

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 Book Edition: 1.

For example, a complete chapter is dedicated to the characterization of biodegradable polymers irradiated with low and heavy ions.

Natural polymers like cellulose (carboxy methyl cellulose) and other marine based polysaccharides (chitin/chitosan, alginates, carrageenans) are predominantly chain-scissioning polymers, and irradiation results in substantial decrease in molecular weight.

This is accompanied with the formation of oxidation products and reduction in crystallinity. Here is the most extensive resource on polymer radiation effects to be available in more than a decade.

This new volume reviews the fundamental chemistry and physics of polymer-radiation interaction and examines recent progress in most major areas of the field.

Its 38 chapters, written by leading experts from around the world, cover: fundamentals of polymer radiation chemistry; technological. The topics covered in this book may be divided into radiation effects on polymers, test methods, radiation processing and other applications of ionizing radiation.
