Brief description of CNC

  • Material: dissolving pulp, cotton, Bleaching kraft pulp (softwood pulp, hardwood pulp), Sisal, Tunicate cellulose
  • Preparation of CNC: acidic hydrolysis (sulfuric acid, hydrochloride acid, phosphoric acid, organic acid)
  • Appearance: suspension or powder, in blue or brown color
  • Various: CNC, chemical modifications of CNC (including TEMPO oxidation (carboxyl content: 0.3 to 2 mmol/g), cationization, carboxymethylation, and polymer grafting)
  • Distribution of particle size:
    • For pulp or cotton CNC: 10-20 nm width, 50-400 nm length.
    • For tunicate CNC: 10-20 nm width, 500 nm to 2 um length (aspect ratio ~ 75)
  • Crystalline index: >70%
  • Dispersion: no hard agglomeration for CNC suspension, can be redispersed in water after drying with ultrasonic treatment. CNC-OA can disperse in organic solvents.
  • Solid content: 0.5% to 10%

Application of CNC

The properties of CNC make it an interesting material for many applications. CNC can be developed for use in applications ranging from cleaning of oil spills, engineering, pharmaceutical and vessel substitutes to biodegradable food packaging. CNC can also replace some petrochemical-based products and is very likely to be cheaper than most other kinds of high-performance nanoscale materials.

Chemical functionalization of CNC improves its dispersibility in organic solvents and this greatly expands its potential applications in various sectors.
