Adhesives Sealants And Coatings For Space And Harsh Environments

New technologies constantly generate new demands for exotic materials to be used in severe environments. The rapid developments of aerospace industries during the last two decades have required new materials to survive extreme high and low temperatures and various radiations. The exploration of new energy sources, e.g., solar and geothermal, has led us to develop new solar collectors and geothermal devices. Even the search for new oils has demanded that we study the corrosive environment of oil fields. In the telecommunication industries, optical fibers have been adopted broadly to replace metallic conductors. However, none of the optical fibers can survive abrasion or corrosion without the application of a coating material. For microelectronics, protection in terms of coatings and encapsulants is deemed necessary to prevent corrosion. One of the major causes of corrosion has been shown to be water which appears to be abundant in our earthly environments. Water can attack the bulk adhesive (or sealant), the interface, or the adherend. Water can also cause delamination of coating film, and it is definitely the major ingredient in causing cathodic or anodic corrosion. Thus, water becomes the major obstacle in solving durability problems of various materials in harsh environments.

This classic reference examines the mechanisms driving adhesion, categories of adhesives, techniques for bond formation and evaluation, and major industrial applications. Integrating recent innovation and improved instrumentation, the work offers broad and comprehensive coverage. This edition incorporates several new adhesive classes, new application topics, and recent developments with nanoadhesives and bio-based adhesives. Existing chapters are thoroughly updated, revised, or replaced and authored by top specialists in the field. Abundant figures, tables, and equations appear throughout the work.

The specialist properties of polysulfide polymers were immediately recognised on discovery, and technology was soon developed to convert these materials into useful products. In this Rapra Review Report, the author describes the factors controlling the structure of polysulfide polymers and the properties which influence their use and performance in products. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.

This book presents the applications of high-energy beam radiation for synthesis and processing of polymeric materials. It addresses fundamental nature of high energy i.e., ionizing radiations and interaction with monomers and polymers leading to a wide variety of products such as tyres, textiles, shape memory polymers, polymers for aviation and space applications, polymeric biomaterials and natural rubber latex. It discusses general principles and techniques of preparation of polymeric materials including polymer blends, composites and nanocomposites. It also includes the topic of radiation-assisted recycling of polymers through breaking of covalent bonds. This book will be useful for students, researchers and professionals in the areas of polymers science and technology, radiation technology, electron beam technology, gamma radiation technology, advanced materials technology, biomaterials technology, nanotechnology, membrane science technology and environmental science.
