Preparation of Cellulose Nanocrystals from α-Cellulose and Optimization of its Isolation Conditions

Cellulose nanocrystals (CNC) are new class of cellulose materials that find wide applications in various research areas over the past two decades. These nanoparticles are usually made by acid hydrolysis of cellulose substances such as wood, cotton, Starch etc. The main aim of this study is to find t...
