This book explores the rapidly advancing field of cellulose-based hydrogels and aerogels, highlighting their immense potential for sustainable applications in materials science, nanotechnology, biomedicine, tissue engineering, energy, and environmental science. With their highly porous structure, eco-friendly nature, excellent biocompatibility, and biodegradability, these materials offer remarkable versatility for next-generation sustainable technologies.

This book presents cutting-edge research on the design, synthesis, and functionalization of cellulose-based hydrogels and aerogels. It demonstrates how their properties can be fine-tuned through integration with organic and inorganic materials and examines their wide-ranging applications in sustainable technologies. Despite their promise, challenges remain in achieving large-scale production with enhanced mechanical properties, controllable modifications, and functionalization for diverse applications. To address these issues, researchers have developed innovative strategies to refine synthesis methods, improve functionality, and expand potential uses.

A valuable resource for researchers, postdoctoral scholars, PhD students, and engineers, this book serves as a comprehensive guide to the latest advancements and future directions in this growing field.
