Description
TEMPO-oxidized cellulose nanocrystals (TOCNCs) constitute a novel class of engineered, rod-shaped, nano-sized particles derived from cellulose fibers through TEMPO-mediated oxidation. This chemical modification introduces carboxyl groups onto the cellulose chains, significantly enhancing their dispersibility and reactivity. These added carboxylate groups notably improve the hydrophilicity of cellulose nanocrystals, rendering them more dispersible in water and other solvents— an advantage of considerable significance for various applications.

APPLICATIONS
TEMPO-oxidized cellulose nanocrystals are characterized by their high aspect ratio, nearly perfect crystalline structure, and the presence of functional groups on their surface. These features endow TOCNCs with exceptional mechanical properties, a large surface area, and the ability to form stable aqueous dispersions. Their unique surface chemistry has paved the way for their use across a wide range of fields.
In biomedical engineering, they find utility in drug delivery systems, tissue engineering scaffolds, and wound healing materials, benefiting from their biological compatibility. In materials science, their reinforcement capabilities are leveraged in polymer nanocomposites to enhance mechanical attributes such as tensile strength and stiffness. Moreover, their biocompatibility and biodegradability align with the growing demand for sustainable and eco-friendly materials, rendering them suitable for applications in packaging, coatings, and functional textiles, where they improve barrier properties and impart functional attributes. Overall, TOCNCs offer a promising platform for advanced materials with a myriad of applications.
