brings together the latest advances in phenol-based polymers, composites, and nanocomposites, covering synthesis, preparation, characterization, processing, and applications. Bio-renewable plant phenols represent a diverse class of chemicals with great industrial significance due to their unique structures and high abundance. The depolymerization process of lignin into small bio-based phenols is a relatively new approach and has received considerable attention recently. This process produces key intermediates, phenolic compounds that can be used to develop and design a wide range of high-performance, bio-renewable, and multifunctional polymers and composites. This book will provide materials scientists and engineers with a useful framework to help take advantage of the latest research conducted in this rapidly advancing field, enabling them to develop and commercialize their own products quickly and more successfully. The book will be of practical interest to academic researchers, industrial scientists, engineers, and advanced students in the area of materials science and engineering, particularly those with an interest in high-performance bio-based polymers and composites.
