Textbook in PDF format This book explores the innovative landscape of functionalized cellulose materials, emphasizing sustainable manufacturing practices and their wide-ranging applications. Advanced functional materials have seen extensive utilization across various sectors, including food processing, pharmaceuticals, cosmetics, electronics, textiles, environmental management, healthcare, and energy, all of which align with the Sustainable Development Goals (SDGs). These materials can be synthesized from both organic (primarily plant-based) and inorganic sources, utilizing sustainable biomass such as wheat, rice straw, wood fibers, and other renewable resources, with or without the incorporation of polymers and nanomaterials. Featuring contributions from leading international researchers, this book provides a comprehensive overview of current challenges and advances in materials science and advanced manufacturing across diverse industries, including cellulose films, aerospace, automotive, marine, and biomedical fields. It covers state-of-the-art topics such as additive manufacturing, 3D printing, bio-manufacturing, and intelligent manufacturing systems. The book highlights key innovations and practical applications of cellulose-based functionalized materials, such as hydrogels, drug delivery platforms, and biomaterials. This field continues to expand through interdisciplinary collaboration, fostering advancements in green chemistry, sustainable manufacturing practices, and materials engineering while addressing pressing challenges in sustainability and circular economy frameworks.
