Cellulose nanocrystal properties and their applications

The main purpose of this work is to provide an overview of recent research in the area of cellulose nonmaterials production from different sources. Due to their abundance، their renewability، high strength and stiffness، being eco-friendly، and low weight; numerous studies have been reported on the isolation of cellulose nanomaterials from different cellulosic sources and their use in high performance applications. This work covers an introduction into the nano cellulose definition as well as used methods for isolation of nanomaterials (nanocrystals) from various sources. The rod-like cellulose nanocrystals (CNC) can be isolated from sources like wood، plant fibers، agriculture and industrial bio residues، tunicates، and bacterial cellulose using acid hydrolysis process. Following this، the paper focused on characterization methods، materials properties and structure. The current review is a comprehensive literature regarding the nano cellulose isolation and demonstrates the potential of cellulose nanomaterials to be used in a wide range of high-tech applications.
