Brief description of CNC
- Material : dissolving pulp, cotton , Bleaching kraft pulp (soft wood pulp, hard wood pulp), Sisal, Tunicate Cellulose (marine biomass, NEW PRODUCT)
- Preparation of CNC: acidic hydrolysis
- Appearance: blue suspension or white powder
- Various: CNC, chemical modifications of CNC( including: TEMPO oxidation (carboxyl content: 0.3 to 2 mmol/g), cationisation, carboxylation 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
- Solid content: 0.5% to 12%（can be adjusted according to customers’ requirement）

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 functionalisation of CNC improves its dispersability in organic solvents and this greatly expands its potential applications in various sectors.
