Those who are working in the design of polymers and polymer nanocomposites need to have a thorough understanding of the underlying mechanisms and processes involved in the ageing and degradation of these materials. Aging and Degradation of Polymer Nanocomposites will provide a comprehensive understanding of the processes and mechanisms involved in the aging and degradation of these materials. The book discusses in detail aging and degradation processes and their implications for the design, development, and use of these materials in various applications. It explores the different aspects of aging and degradation and investigates the ways these materials deteriorate over time. Special attention is given to the role of nanofillers, emphasizing their effects on various properties like thermophysical, mechanical, and electrical. The book looks at the various factors that contribute to aging and degradation, including exposure to environmental conditions like heat, light, radiation, and moisture, as well as mechanical stress and degradation due to chemical reactions. It also covers various techniques and approaches used to study aging and degradation, including analytical methods, simulations, and experimental analysis, and provides insights into the mechanisms involved. Additionally, the book covers strategies such as the use of additives, stabilizers, surface treatments and protective coatings, to mitigate or prevent aging and degradation of these materials. The book will be a valuable reference resource for academic and industrial researchers, materials scientists and engineers, and polymer chemists and physicists working in the design of polymers, polymer composites and polymer nanocomposites.
