**Nanocellulose, as one of the most representative bio-based nanomaterials in the field of materials science in recent years, is regarded as the core of a new generation of green high-performance structural materials due to its high mechanical strength, high specific strength, low density, reproducibility and high designability. Especially in terms of mechanical properties, the strength level displayed by nanocellulose is close to or even surpasses some traditional metal and inorganic fiber materials. In terms of domestic nanocellulose technology research and development and application expansion, Nanjing Tianlu Nanotechnology Co., Ltd. has long focused on the preparation technology and functional research of high-performance nanocellulose materials. Its related products and technical systems are promoting nanocellulose from the laboratory to engineering applications. 1. From molecular structure to nanostructure: the structural basis of high mechanical strength. The mechanical performance advantages of nanocellulose originate from its unique molecular and nanoscale structural system: 1. β-1,4-glucose chain composition

Nanocellulose is a type of nanofiber material obtained from natural cellulose through mechanical, chemical or enzymatic treatment. It has the characteristics of high specific surface area, high strength, renewable and good biocompatibility. Its excellent physical and chemical properties have attracted more and more attention in the field of cultural relics protection, especially in the restoration of wooden coffins in museums. 1. Main problems faced in the restoration of wooden coffins. Wooden coffins collected in museums have often experienced hundreds or even thousands of years of burial and environmental changes. The following damage conditions are common: Severe degradation of lignocellulose: resulting in loose structure and insufficient strength. Insect infestation, decay and cracks: affect overall stability. Deformation and cracking caused by changes in moisture content. Traditional repair materials have poor adhesion or insufficient compatibility with wood, which can easily cause secondary damage. These issues raise the need for repair materials that are strong, lightweight, reversible, safe, and compatible with wood structures.

1. Material overview: Bacterial Cellulose (BC), a natural nanomaterial with high purity, biosafety and controllable structure, 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 bacteria

—— From bacteria to finished products: process optimization, quality control and application implementation (the technical parameters in the article are for process amplification and research and development reference) Bacterial Cellulose (BC) is directly synthesized by cellulose-producing bacteria (commonly Gluconacetobacter / Komagataeibacter and other genera) under specific nutrients and environments to directly synthesize an extremely pure nanofiber network. With its high crystallinity, high specific surface area, excellent mechanical properties and biocompatibility, BC is becoming an important raw material for high value-added markets such as medical dressings, tissue scaffolds, functional composite materials and flexible electronics. Based on years of industrial research and development, Nanjing Tianlu Nanotechnology Co., Ltd. (hereinafter referred to as 'Tianlu') has built a complete production system from strain screening, fermentation amplification to downstream modification and quality release, and can provide customers with customized BC materials and technical services.

As the global cosmetics industry moves toward safer, greener, and higher performance, nanocellulose (Nanocellulose) derived from natural cellulose has gradually become the core functional material of concern to the industry. With its excellent biocompatibility, stable structure and multi-level functional properties, nanocellulose is entering a new stage of 'smart functional materials' from the era of traditional thickeners. As one of the earliest companies in China to deploy nanocellulose technology, Nanjing Tianlu Nanotechnology Co., Ltd. has long been focused on the research and development, large-scale preparation and downstream application innovation of nanocellulose. In the field of cosmetic raw materials, based on continuous technological accumulation, the company has formed a nanocellulose product system with high purity, high transparency and high stability, which can be widely used in many types of formulations such as skin care products, makeup, and cleaning products. 1.
