Nanjing Tianlu Nano Technology Co., Ltd. is a high-tech enterprise specializing in the research, development, production and sales of nanocellulose dispersions . The company is located in Jiangning District, Nanjing City, equipped with advanced nano-processing equipment and a complete quality testing system. We have long provided high-dispersion and strong suspension stability nanocellulose aqueous dispersion products for food packaging, coatings, medical materials, new energy and other fields, and are committed to promoting the industrial application of green and environmentally friendly materials.
With the continuous advancement of the concept of green and low-carbon, nanocellulose dispersion (Nanocellulose Dispersion) is attracting high attention from various industries as a new generation of biodegradable materials. It uses natural cellulose as raw material and nano-treated aqueous suspension, which has high dispersion, suspension stability, mechanical enhancement and environmentally friendly and degradable properties. It is widely used in food packaging, coating additives, biomedical materials, cosmetics and new energy materials .
The nanocellulose dispersion is a stable colloid system formed by uniformly dispersing The fiber diameter is usually 5-50 nanometers and can reach a length of several microns, forming a high aspect ratio network structure. This structure gives it nano-scale cellulose in water. light weight, high strength and excellent suspension stability。
According to the preparation method, the nanocellulose aqueous dispersion is mainly divided into:
CNF (Cellulose Nanofibrils) dispersion : network-like structure, good flexibility, suitable for reinforced composite materials.
CNC (Cellulose Nanocrystals) dispersion : rigid rod-like structure, high crystallinity, mostly used in functional coatings and optical applications.
Bacterial cellulose dispersion : obtained by microbial fermentation, high purity, stable three-dimensional structure, suitable for medical materials.
High dispersion and suspension stability : It is evenly distributed in an aqueous system for a long time, and is not easy to settle or agglomerate. It is suitable for food packaging coatings, cosmetic emulsions and other systems.
Degradable nanocellulose materials : derived from plant fibers or bacterial cellulose, environmentally friendly and non-toxic, without microplastic pollution after degradation.
Significant improvement in mechanical properties : adding a small amount can significantly improve the strength, barrier properties and thermal stability of the matrix material.
Surface functionalization : chemical modification can introduce hydrophobic, conductive, antibacterial and other functions to meet the needs of multiple fields.
