What are the advantages of TEMPO-oxidized nanocellulose? How should one choose among different carboxyl contents?
TEMPO-oxidized nanocellulose, in English TEMPO-oxidized Cellulose Nanofibrils, abbreviated as TOCNF or TO-CNF, is a type of cellulose nanofiber with carboxyl groups on its surface. TEMPO oxidation can preferentially convert the primary hydroxyl groups at the C6 position of cellulose into carboxyl groups. In neutral or slightly alkaline aqueous dispersion systems, the carboxyl groups usually exist in the form of —COO⁻ or —COONa, giving the fiber surface a negative charge.
What Are the Differences Between CNC, CNF, and BC? How Should You Choose?
Although CNC, CNF, and BC/BNC are all classified as nanocellulose, they exhibit significant differences in microstructure, aspect ratio, network-forming capability, product form, and application suitability. This article compares the characteristics of these three types of nanocellulose in terms of material structure, key properties, and typical applications, helping research and industrial users quickly select the most suitable material based on their specific objectives.

Why Does CNF Thicken and Stabilize Suspensions at Low Dosages?
This article explores how nanocellulose (CNF) delivers effective thickening and suspension stabilization at low addition levels, focusing on its high aspect ratio, fiber entanglement, and three-dimensional network formation, while examining the effects of rheological behavior, dispersion state, dosage, and formulation environment.
How to Achieve Better Nanocellulose Dispersion? A Practical Guide to CNC and CNF Dispersion Methods
The dispersion state of nanocellulose directly affects its performance in reinforcement, thickening and rheological control, suspension stabilization, film formation, and composite applications. Since CNC, CNF, and surface-functionalized nanocellulose products may require different dispersion approaches, this article presents practical procedures covering solvent selection, addition sequence, concentration control, stirring, ultrasonication, and high-shear dispersion.
