Cellulose nanofibers (CNF) are one type of cellulose nanomaterials which are made purely from cellulose molecules. The diameters of CNFs are less than 100 nm and lengths vary from a few microns to several microns. They have shown remarkable mechanical properties compared with other natural fibers as well as glass and carbon fibers. Excepting abundance, renewability and biodegradation, CNF possesses other outstanding advantages such as excellent mechanical properties, well light transparency, large surface area and high reactivity, and is one of the study hotpots in biomass nanomaterials.
Catalytic oxidation using TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical) has opened a new field of efficient and selective conversion chemistry of alcoholic hydroxyl groups to aldehydes, ketones and carboxyl groups under mild conditions. Alfa Chemistry cellulose nanofibers (by chemical method) are obtained by TEMPO-mediated oxidation and successive mild disintegration in water.

Alfa Chemistry cellulose nanofibers can be used in coatings and films as well as paints, foams and packaging. They also have applications in hygiene and absorbent products such as antimicrobial films, super absorbent polymers, non-woven products, super water absorbent material, tissues and absorbent structures. In addition, they can find applications in manufacturing highly scattering material for ultra-white coatings, high-flux membranes, battery separators, reinforcement of conductive materials, loud-speaker membranes, computer components, lightweight body armor and ballistic glass, capacitors and corrosion inhibitors.
