It has achieved breakthroughs in papermaking, composite materials, biomedicine and other fields, and has become a key force in promoting the green transformation of the industry.

As an R&D and industrialization enterprise focusing on the field of nanocellulose, Nanjing Tianlu Nanotechnology Co., Ltd. (hereinafter referred to as ' Nanjing Tianlu ' ) is based in Nanjing. Relying on regional resources and technological advantages, it deeply cultivates this field and promotes nanocellulose from laboratory to large-scale application. It provides professional and efficient green material solutions to various industries and assists the high-quality development of the industry.

1. Nanocellulose: a ' green super material ' derived from nature

Nanocellulose ( Nanocellulose ) is a new biomass material that disassembles natural cellulose fibers to a scale of 1-100 nanometers through physical, chemical or biological methods. It is widely found in agricultural and forestry wastes such as wood, cotton and linen, and straw. It is one of the most abundant natural polymer materials on the earth.

According to differences in preparation methods and structures, nanocellulose is mainly divided into three categories: cellulose nanocrystals ( CNC ), cellulose nanofibrils ( CNF ), and bacterial nanocellulose ( BNC ). Each has unique properties and is suitable for different high-end application scenarios:

• Cellulose Nanocrystal ( CNC ): Rod-like crystal structure, strong rigidity, high crystallinity, modulus up to 100-150GPa , it is the core reinforcing component of high-end composite materials;

• Cellulose nanofibrils ( CNF ): fibrillar structure, excellent flexibility, large specific surface area, can form a dense three-dimensional network, suitable for the preparation of degradable films, coatings and other products;

• Bacterial nanocellulose ( BNC ): synthesized by microbial fermentation, has high purity and excellent biocompatibility, and is suitable for sensitive scenarios such as biomedicine and high-end daily chemicals.

Compared with traditional petroleum-based materials, the biggest advantage of nanocellulose is that it is ' green and sustainable ' - it is made from nature, can be completely degraded after use, and leaves no environmental residue. It perfectly fits the ' double carbon ' goal and the development trend of environmental protection. It is also lightweight, high-strength, and has customizable functions. It is hailed as the ' super material of the green era ' in the industry.。
