Extensive uses of polymers are because of their variety of physical properties including their electrical and thermal properties. Further, they have become ubiquitous materials in modern manufacturing processes and offer a wide variety of chemical and mechanical prope-rties applicable to numerous problems. The polymer properties depend on their structural characteristics brought about by chemical methods. Changes in the chemical and physical properties of polymer at the surface region may be easily derived by chemical and/or structural modifications which can be achieved by variation of chemical functionality, and surface texture. However, rough and/or damaged surfaces (through) bond scission, carbonization, cross-linking, etc are produced by the above methods. Therefore, new surface modification methods are required to obtain polymer surfaces free of surface damage.

Polymer materials are used in different fields of industries, from microelectronice to medicine. Ion beam implantation is method of surface modification when surface properties must be significantly changed and bulk properties of material must be saved. Ion Beam Treatment of Polymers contains results of polymer investigations and techniques development in the field of polymer modification by high energy ion beams. This book is intended for specialists in polymer science who have interest to use an ion beam treatment for improvement of polymer properties, for specialists in physics who search a new application of ion beam and plasma equipment and also for students who look for future fields of high technology. Chapter 1-3 are devoted to overview of the basic processes at high energy ion penetration into solid target. The historical aspects and main physical aspects are covered. A basic equipment principles and main producers of equipment for ion beam treatment are considered. Chapter 4 contains chemical transformations in polymers during and after high energy ion penetration. The modern methods and results of experimental and theoretical investigation are described. Chapters 5-10 are devoted to properties of polymers after ion beam treatment, regimes of treatment, available applications, in particular: increase of adhesion of polymers and a mechanism of an adhesion increase, wetting angle of polymer by water and its stability, adhesion of cells on polymer surface, drug release regulation from polymer coating and others. Chapter 11 contains our last results on polymerisation processes in liquid oligomer composition under high vacuum, plasma and ion beam conditions as simulation of free space environment. * By scientists working in polymer chemistry, physics of ion beam implantation and in development and production of ion beam equipment * Covering industrial and scientific applications of ion beam implanted polymers * Also for students with an interest in future fields of high technology

Presented in two parts, this first comprehensive overview addresses all aspects of energetic ion irradiation of polymers. Earlier publications and review articles concentrated on selected topics only. And the need for such a work has grown with the dramatic increase of research and applications, such as in photoresists, waveguides, and medical dosimetry, during the last decade. The first part, Fundamentals of Ion Irradiation of Polymers covers the physical, chemical and instrumental fundamentals; treats the specific irradiation mechanisms of low- and high-energy ions (including similarities and differences); and details the potential for future technological application. All the new findings are carefully analyzed and presented in a systematic way, while open questions are identified.

The second volume, Transport Processes in Ion Irradiated Polymers deals with transport processes in both unirradiated and irradiated polymers. As both a review and a stimulus, this work seeks to contribute substantially to the literature and advancement of polymeric devices, from both the low- and high-energy regimes.

This conference consisted of 15 oral sessions, including three plenary papers covering areas of general interest, 22 specialist invited papers and 51 contributed presentations as well as three poster sessions. There were several scientific highlights covering a diverse spectrum of materials and ion beam processing methods. These included a wide range of conventional and novel applications such as: optical displays and opto-electronics, motor vehicle and tooling parts, coatings tailored for desired properties, studies of fundamental defect properties, the production of novel (often buried) compounds, and treating biomedical materials. The study of nanocrystals produced by ion implantation in a range of host matrices, particularly for opto-electronics applications, was one especially new and exciting development. Despite several decades of study, major progress was reported at the conference in understanding defect evolution in semiconductors and the role of defects in transient impurity diffusion. The use of implantation to tune or isolate optical devices and in forming optically active centres and waveguides in semiconductors, polymers and oxide ceramics was a major focus of several presentations at the conference. The formation of hard coatings by ion assisted deposition or direct implantation was also an area which showed much recent progress. Ion beam techniques had also developed apace, particularly those based on plasma immersion ion implantation or alternative techniques for large area surface treatment. Finally, the use of ion beams for the direct treatment of cancerous tissue was a particularly novel and interesting application of ion beams.

Materials science is the prime example of an interdisciplinary science. It - compasses the ?elds of physics, chemistry, material science, electrical en- neering, chemical engineering and other disciplines. Success has been o- standing. World-class accomplishments in materials have been recognized by NobelprizesinPhysicsandChemistryandgivenrisetoentirelynewtechno- gies. Materials science advances have underpinned the technology revolution that has driven societal changes for the last ?fty years.

All fall in the technology domain. In every case proposed solutions begin with new forms of materials, materials processing or new arti?cial material structures. Scientists seek new forms of photovoltaics with greater e?ciency and lower cost. Water purity may be solved through surface control, which promises new desalination processes at lower energy and lower cost. Revolutionary concepts to extend the information revolution reside in controlling the “spin” of electrons or enabling quantum states as in quantum computing. Ion-beam experts make substantial contributions to all of these burgeoning sciences.

Ion Beam Treatment of Polymers, Second Edition presents the results of polymer investigations and technique development in the field of polymer modification by high-energy ion beams. It shows how to use ion beam equipment in the polymer industry, as well as how to use it to produce new polymer materials. The authors, scientists and researchers active in the field, provide analysis and data from their work, and give an overview of related work by others. The authors focus on wetting, adhesion, hardness, chemical activity, environmental stability, biocompatibility, new synthesis methods, and space flight construction. The technologies of material modification by a beam of high energy ions have wide applications in different fields, from microelectronics to medicine. Historically, ion beam treatment of polymers had fewer applications due to high costs of ion beam equipment and low costs of polymer materials. The modern development of new pulse sources with a high current density and wide ion beams increase the effectiveness of ion beam technology for polymers. Collates data from many scientists working in polymer chemistry, physics of ion beam implantation, and in development and production of ion beam equipment Covers industrial and scientific applications of ion beam implanted polymers Integrates physical and chemical aspects of the processes in polymers treated by ion beams.
