Properties and applications of nanocellulose

With the continuous advancement of green materials and sustainable development concepts, nanocellulose ( Nanocellulose ) is becoming an important direction for global new material research and industrialization due to its unique structure and excellent performance. As a high-performance nanomaterial extracted from natural cellulose, it is not only renewable, non-toxic and environmentally friendly, but also lightweight, high-strength, transparent and flexible, and has brought technological innovation to many industries.

1. Core performance advantages of nanocellulose

Excellent mechanical properties
The specific strength and specific modulus of nanocellulose are comparable to steel. Its strength comes from the dense hydrogen bonding between cellulose molecules and the nanoscale fiber structure. This high-strength property makes it an ideal reinforcement material that can significantly improve the structural stability of composite materials.

Excellent dispersion and film-forming properties
After surface modification such as TEMPO oxidation, nanocellulose shows excellent dispersion and stability in the aqueous phase, and can self-assemble to form a highly transparent film. Nanjing Tianlu Nano Technology Co., Ltd. uses self-developed modification technology to greatly improve the compatibility of its products in coatings, inks and functional film materials.

Good biocompatibility and degradability
As a natural organic polymer, nanocellulose is completely biodegradable and will not cause environmental pollution. It also has good biocompatibility and is suitable for biomedical materials such as medical dressings and tissue scaffolds.

High specific surface area and adsorption performance
Its nanostructure gives a huge specific surface area and abundant surface active groups, which can achieve efficient adsorption of metal ions, organic dyes and gas molecules, providing a new direction for environmental management and energy storage materials.

Main application areas of nanocellulose

Green packaging and degradable plastic replacement
Nanocellulose has high mechanical strength and barrier properties. It can be compounded with starch, bio-polylactic acid ( PLA ) and other materials to prepare degradable packaging films to reduce white pollution.

Functional coating and ink additives
have good dispersion and film-forming properties, making them useful as environmentally friendly coating thickeners and stabilizers. The nanocellulose dispersion developed by Nanjing Tianlu Nano Technology Co., Ltd. has demonstrated significant thickening and wear-resistant effects in water-based ink and paper coating.

Biomedical material
nanocellulose has excellent biocompatibility and hygroscopicity, and can be used to prepare high value-added products such as medical dressings, artificial skin, and drug sustained-release carriers, helping the medical industry transition to biodegradability.

The transparent conductive properties of electronic and energy materials
enable them to be used in flexible display films, supercapacitor separators and lithium battery electrolyte carriers, demonstrating the huge potential of ' green electronic materials ' .
