Frequently Asked Questions
- What is the source of Nano Fibrillated Cellulose?
- The raw material is cotton.
- What is the surface charge of CNF?
- The surface is carboxymethylated. CNF is modified by carboxymethylation before undergoing mechanical processing.
- Is CNF hydrophilic?
- Yes, it is hydrophilic. Using a high-pressure homogenizer (40MPa, 2-3 cycles), it can disperse in water.
- How is CNF dried?
- It is produced using a normal drying process.
- Does CNF have surface functional groups?
- Yes, CNF contains hydroxyl (-OH) and carboxyl (-COOH) groups, with a carboxyl content of 2.5 mmol/g (measured via conductivity titration). These groups are highly stable.
- What is the main functional group in CNF?
- The primary functional group is -OH (hydroxyl group).
Applications of Cellulose Nanofiber
1. Body Armor Applications
The crystal structure of nanocellulose consists of tightly packed needle-like crystals, making it eight times stronger than stainless steel. This incredible strength makes CNF a promising material for future body armor innovations.
2. Flexible Batteries
Traditional battery separators are thick and rigid, making them unsuitable for flexible applications. Nanocellulose combined with graphene can lead to the development of bendable, ultra-thin batteries, revolutionizing the electronics industry.
3. Flexible Screens
Due to its bendability, transparency, lightweight, and high strength, nanocellulose is a prime candidate for replacing plastic or glass in future flexible display technologies.
4. Advanced Filtration Systems
Nanocellulose is an excellent filter material, capable of purifying various liquids, including:
- Desalinating seawater for drinking purposes
- Filtering harmful chemicals from cigarette smoke
- Purifying blood during medical transfusions
5. Absorbent Aerogels
When combined with aerogel foams, nanocellulose creates highly porous, ultra-light absorbent materials. These can be used in advanced wound dressings and hygienic products.
6. Fuel-Efficient Vehicles
Nanocellulose can be obtained from algae, making it a low-cost, sustainable material. Car components made with nanocellulose-reinforced composites are significantly lighter, reducing fuel consumption and enhancing vehicle efficiency.
7. Biofuel Production
By genetically modifying algae, it is possible to produce biofuel alongside nanocellulose. While the resulting material may differ slightly from pure CNF, it represents a breakthrough in sustainable energy production.
