1. Overview of materials: natural nanomaterials with high purity, biosafety and controllable structure

Bacterial cellulose ( Bacterial Cellulose ，BC ) is produced by microorganisms such as Acetobacter in a fermentation system, forming a three-dimensional network with high crystallinity and nanoscale fiber structure. Its fiber diameter is usually between 20-100 nm , its purity exceeds 99% , and it does not contain common impurities in plant fibers such as lignin and hemicellulose. Therefore, it is significantly better than traditional plant cellulose in terms of structural uniformity, performance stability and biocompatibility.

As an enterprise that has long been focused on the research and development and industrialization of nanocellulose materials, Nanjing Tianlu Nanotechnology Co., Ltd. has established a complete technical system and product system in the fields of bacterial cellulose, nanocellulose and their derivative materials. Relying on advanced fermentation technology, green preparation processes and stable production capacity, the company is able to provide high-purity, high-performance bacterial cellulose raw materials and customized solutions to meet the needs of multiple industries such as medical, cosmetics, food packaging and functional materials.
