Description
TEMPO-oxidized cellulose nanofibers (TOCNFs) represent a new category of ultrafine fibers, generated through a controlled oxidation process of cellulose fibers using the TEMPO reagent. This chemical modification introduces carboxyl groups onto the cellulose chains, thereby transforming the cellulose fibers into nanofibers with enhanced surface chemistry and functionality. The introduction of carboxyl groups on the surface of the fibers enhances their dispersibility in aqueous solutions, compatibility with various matrices, and ability to form strong, flexible films. Moreover, the surface chemistry of these nanofibers can be tailored to specific requirements, offering versatility in various fields.
