Cellulose Nanofiber (Cellulose Nanofibril, Nanofibrillated Cellulose, CNFs)
Wide: 10-20 nm, Length: 2-3 ?m, Dry powder
Cellulose Nanofibril is originally generated from wood-derived fibrils with length in the micrometer and width in the nanometric range during the biosynthesis of cellulose.
Today, there is widespread scientific and commercial interest in cellulose nanofibrils (CNF). There have several application areas including foods, cosmetics, pharmaceuticals, paints, drilling muds, paper additives and paperboard barriers, medical products, etc. Our Nanofibrillated Cellulose product competes on price and performance with counterparts.

Applications
Crystal structure of nanocellulose is consisting from packed array of needle-like crystals. These crystal structures are incredibly tough and their strength value is nearly eight times higher than stainless steel. Therefore, nanocellulose can be perfect building material for the future body armor studies.
Generally, separator parts inside batteries made up from thick and stiff material which cannot be used for bendable applications.
Instead of these materials, flexible and thin nanocellulose combined with graphene material, flexible battery as the one of the big dream in electrical industry can be produced.
Nanocellulose is bendable, transparent, light and strong material therefore it can easily take place of the plastic or glass.
In the future, nanocellulose will be one of the best material for bendable screen studies.
Nanocellulose can be used to filter and purify many types of liquids such as purifying saltwater to be drinkable, trapping dangerous chemicals in cigarette and filtering out blood cell during transfusion.
When the nanocellulose are mixed with the aerogel foam, incredibly porous and adsorbent material can be obtained that could make strong and light wound-dressing and tampons.
Nanocellulose can be obtained by algae and actually, this is quite cheap production method. Therefore, it will be possible to use it in serious bulk materials. In the cars, components from stuff to interior trim will be produced from the light composites reinforced with nanocellulose. By this way, decrease in the weight of the components will save the fuel consumption of the cars.
During the production of nanocellulose by algae, it is possible to obtain biofuel at the same time by changing the DNA of the helpful bugs. Result of these process actually will not produce real nanocellulose material, but it will bring into useful byproduct.
Frequently Asked Questions About CNF
The raw material is cotton
Surface is carboxymethylated. CNF is modified by carboxymethylation and then mechanically processed.
Yes, it is hydrophilic, using high-pressure homogenizer 40MPA 2-3 times, it can disperse in water.
It is made by normal dry
- The surface of CNF contains both hydroxyl and carboxyl groups, and the carboxyl content is 2.5 mmol/g (determined by conductivity titration).
- The carboxyl group is relatively stable, and it is difficult to change it under environmental conditions
The main functional group is -OH.
