An indispensable volume detailing the current and potential applications of atmospheric pressure plasma treatment by experts practicing in fields around the world Polymers are used in a wide variety of industries to fabricate legions of products because of their many desirable traits. However, polymers in general (and polyolefins, in particular) are innately not very adhesionable because of the absence of polar or reactive groups on their surfaces and concomitant low surface energy. Surface treatment of polymers, however, is essential to impart reactive chemical groups on their surfaces to enhance their adhesion characteristic. Proper surface treatment can endow polymers with improved adhesion without affecting the bulk properties. A plethora of techniques (ranging from wet to dry, simple to sophisticated, vacuum to non-vacuum) for polymer surface modification have been documented in the literature but the Atmospheric Pressure Plasma (APP) treatment has attracted much attention because it offers many advantages vis-a-vis other techniques, namely uniform treatment, continuous operation, no need for vacuum, simplicity, low cost, no environmental or disposal concern, and applicability to large area samples. Although the emphasis in this book is on the utility of APP treatment for enhancement of polymer adhesion, APP is also applicable and effective to modulate many other surface properties of polymers: superhydrophilicity, superhydrophobicity, anti-fouling, anti-fogging, anti-icing, cell adhesion, biocompatibility, tribological behavior, etc. The key features of Atmospheric Pressure Plasma Treatment of Polymers: Address design and functions of various types of reactors Bring out current and potential applications of APP treatment Represent the cumulative wisdom of many key academic and industry researchers actively engaged in this key and enabling technology

Over the last decade, or so, the growth in the use of adhesives, especially in ever more technically demanding applications, has been rapid and many major developments in the technology of adhesives have been reported. This growth has also led to attention being focused on somewhat more basic studies of the science of adhesion and adhesives, and in recent years our level of fundamental knowledge concerning the formation and mechanical performance of adhesive joints has increased dramatically. Such studies have, of course, been aided greatly by the development of the tools at the disposal of the investigators. For example, specific surface analytical techniques, such as X-ray photoelectron and secondary-ion mass spectroscopy, and the increasingly sophisticated methods of stress analysis and fracture mechanics have been put to good use in furthering our understanding of the science of adhesion and adhesives. The present book attempts to review the multidisciplined subject of adhesion and adhesives, considering both the science and technology involved in the formation and mechanical performance of adhesive joints. The author would like to thank his friends and colleagues for useful discus sions and help in the preparation of this book. I am particularly grateful to P. Cawley, J. Comyn, W. A. Lees, A. C.
