This book explores various aspects of nanocellulose and its composites, beginning with its resources such as bacterial sources, biomass, and other lignocellulosic materials and covering the different types of microfibrillated cellulose (MFC), nanofibrillated cellulose (NFC), and nanocrystalline cellulose (NCC). It also discusses production processes, characterization techniques, and diverse industrial applications. The book outlines multiple extraction methods for producing nanocellulose from various forms and sources, along with an overview of the industries and products that currently employ nanocellulose. Features:Provides comprehensive coverage of nanocellulose, offering readers an in-depth understanding of its sources, classifications, and types. Highlights real-world applications in industries such as cement and polymer nanocomposites. Focuses on scalability and detailed extraction processes. Examines environmental sustainability aspects of nanocellulose-based solutions. Reviews extraction techniques across major nanocellulose categories (MFC, NFC, NCC, and bacterial nanocellulose). This book is intended for researchers and graduate students in chemical engineering, biomaterials, and advanced materials.
