TEMPO-modified cellulose nanocrystals (CelluloseNanocrystal(CNC)modified byTEMPO Medium) are usually obtained by acid hydrolysis and TEMPO oxidation hydrolysis of cellulose amorphous region, retaining the crystalline region and obtaining a needle-like crystalline cellulose with a length of several hundred nanometers and a diameter of 3-7nm. TOCNC has a special nano-size, high mechanical strength and Young's modulus, high crystallinity and special optical properties, and its dispersion is light blue translucent.

Product parameters:

Raw materials: dissolving pulp, cotton pulp, bleached kraft pulp (coniferous wood pulp and hardwood pulp), bamboo pulp, etc.

CNC preparation method: TEMPO/NaBr/NaClO system, sulfuric acid hydrolysis, hydrochloric acid hydrolysis (optional)

Appearance: light blue suspension or white powder/particle size distribution: 90-300nm

Crystallinity:> 90%

Carboxyl content: 1.0-3.0mmol/g

Supply form: liquid dispersion: concentration of 0.9-1.5%.

TOCNC applications: can be used as a template agent, drug release, material enhancement, membrane materials, carriers, daily chemical, coatings, food, emulsion dispersion, optical materials and other applications.
