TEMPO Oxidized Cellulose Nanofibers (TOCNFs)



Wishlist icon Add to wishlistAdd to wishlist


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.

TEMPO-oxidized cellulose nanofibers (TOCNFs) offer a combination of unique properties: high aspect ratios, large surface area, tunable surface chemistry, robust mechanical strength, and biocompatibility. These characteristics enable their wide-ranging applications across the biomedical, materials science, and environmental sectors, establishing them as a promising material for various innovative technologies.

TEMPO-oxidized cellulose nanofibers are utilized in a wide array of applications. In biomedical engineering, they are used in drug delivery systems, wound dressings, and tissue engineering scaffolds. Their compatibility with biological systems enhances cell adhesion, proliferation, and overall biocompatibility. In materials science, TOCNFs are incorporated into composite materials to enhance their strength, stiffness, and durability. They also serve as effective additives in coatings, offering functionalities like barrier properties and surface modification. Moreover, TOCNFs are employed in producing environmentally friendly packaging materials, as thickeners in cosmetics and food products, and as filtration and absorbent materials. Their biodegradability and minimal environmental impact make them an attractive choice for developing sustainable materials.
