Handbook of Thermosetting Foams, Aerogels, and Hydrogels: From Fundamentals to Advanced Applications presents the latest on the preparation, characterization, properties and applications of thermoset foams, aerogels and hydrogels. The book begins by introducing each of these concepts and their characteristics, current applications, potential for further development, and environmental impacts. This is followed by three sections, each focusing on foams, aerogels and hydrogels developed from a specific thermosetting polymer category, covering polyurethane, epoxy resins and formaldehyde. In each section, detailed coverage includes preparation, structure, characterization, properties, processing and applications based on material, along with key challenges in design, processing, implementation and solutions. This is a valuable resource for researchers and advanced students with an interest in thermoset lightweight materials across the disciplines of polymer science, chemistry, nanotechnology, materials science and engineering. The book will also be of interest to R&D professionals, engineers and scientists working with foams, hydrogels and aerogels for a range of applications and industries.
