Abstract : The increasing demand for sustainable materials has prompted extensive research on cellulose nanocrystals (CNCs) derived from various plant fibers. CNCs exhibits exceptional properties, like high aspect ratio, biodegradability, and biocompatibility. However, the tendency of CNC to form agglomerates limits its applications. Ultrasonication is commonly employed to disperse CNC in water and break the agglomerates. This review offers an overview of CNC isolation methods from different plant sources, emphasizing the influence of factors like fiber source and hydrolysis conditions on CNC characteristics. Acid hydrolysis, enzymatic hydrolysis, mechanical treatment, and ionic liquid treatment are among the methods explored for CNC isolation. The review also outlines the various steps involved in CNC isolation, including biomass source selection, pre-treatment, acid hydrolysis, removal of alkali-soluble components, bleaching, centrifugation, dialysis, ultrasonic treatment, and characterization of CNC properties. The physical and chemicalproperties of CNCs as morphology, crystallinity, and surface chemistry, differ dependent on the plant resource and methodof isolation. The findings contribute to a better understanding of sustainable CNC production from various biomass sources. Keywords - CNC Isolation, Plant Fibers, Plant Oil CNC, Plant Seed CNC, CNCs Properties, Reinforcement Applications.
