Cellulose nanocrystals: A versatile biobased nano material

Cellulose nanocrystals (CNCs) are a type of bio-based nanomaterial derived from cellulose, the most abundant biopolymer on Earth. CNCs are rod-shaped sustainable nanoparticles with exceptional mechanical strength, high aspect ratio, and high crystallinity, among other special qualities. Due to their potential applications in various domains, including materials science, biomedical engineering, and renewable energy, these nanomaterials have garnered significant attention in recent years. Using acid hydrolysis or other top-down methods, CNCs can be recovered from various cellulosic sources, including cotton, wood, and bacterial cellulose. The surface chemistry of CNCs can be modified to provide specific functions, thereby expanding their range of applications to include energy storage, biomedicine, and nanocomposites. This article outlines CNC production, characteristics, and uses, emphasizing the material's promise as a sustainable nanomaterial for cutting-edge technologies. The importance of CNCs in the creation of high-performance and sustainable materials is emphasized by the discussion of recent developments in CNC-based materials and their possible effects on different industries.
