Engineering of Natural Polymeric Gels and Aerogels for Multifunctional Applications brings together detailed information on gels, hydrogels, and aerogels derived from natural polymers, covering materials, processing, fabrication techniques, structure-property relationships, and novel applications. The book begins by introducing polymeric gels, hydrogels, and aerogels, the different types and properties, advantages and disadvantages, manufacturing techniques, production and scalability, and the possible applications. This is followed by thorough coverage of processing methods for obtaining natural polymer-based gels and hydrogels, with separate chapters focusing on physical processes, chemical processes, green processes, and processing for aerogels. The final chapters of the book focus on the preparation of natural polymer-based gels, hydrogels, and aerogels for many state-of-the-art applications, including biomedical, absorbent, energy saving, filtration, and sensing areas. Engineering of Natural Polymeric Gels and Aerogels for Multifunctional Applications is an essential resource for all those with an interest in polymeric gels and natural polymers, including researchers and scientists in polymer engineering, polymer chemistry, sustainable materials, biomaterials, materials science and engineering, and chemical engineering. In industry, this book supports scientists, R&D, and engineers looking to utilize novel bio-based materials for advanced applications.
