Advanced application of nanocellulose in the aviation field - Nanjing Tianlu Nano Technology Co., Ltd. promotes innovation in green aviation materials. As the global aviation industry moves towards a development stage of lighter weight, safer, greener and high-functional integration, aviation equipment manufacturing is facing an important turning point in the upgrading of material systems. Although traditional metal materials and carbon fiber composite materials have experienced multiple generations of evolution, they still have bottlenecks in terms of sustainability, manufacturing energy consumption, and functional compatibility. Nanocellulose (Nanocellulose), as a new generation of advanced composite material reinforcement technology, is widely considered to be an important direction for future aviation material innovation due to its ultra-high specific strength, functionalizable interface, and green and sustainable characteristics. In the classification, cellulose nanocrystals (CNC) are widely used in

1. Introduction As the global demand for sustainable materials and green manufacturing technologies continues to grow, traditional petrochemical-based materials are facing the challenge of upgrading. In recent years, bacterial cellulose (BC), as a high-purity nanoscale polysaccharide material self-synthesized by microorganisms, has become a research hotspot in the field of polymer materials science and biomanufacturing due to its excellent structural controllability, biocompatibility and degradability. Nanjing Tianlu Nanotechnology Co., Ltd. has long been focusing on the research, development and application of nanocellulose, bacterial cellulose and their composite materials. Relying on a sophisticated biological fermentation platform and material characterization system, the company has established a full-chain R&D system from laboratory research to pilot scale-up, and is committed to promoting the industrial application of bacterial cellulose in the fields of medical care, flexible electronics, packaging and functional film materials. 2. Scientific characteristics at the molecular and structural levels Bacterial cellulose is composed of β-1,4-glucose units

With the further advancement of the concept of green materials and sustainable development, nanocellulose (Nanocellulose) is becoming a research hotspot in the field of new materials worldwide due to its excellent mechanical properties, biocompatibility and environmental friendliness. As a high-performance nanomaterial derived from natural cellulose, the optimization of its preparation process directly determines the performance and application scope of the product. Nanjing Tianlu Nanotechnology Co., Ltd. has continuously explored more efficient and stable nanocellulose preparation technologies during many years of R&D and industrialization, providing reliable technical support to the industry. 1. Preparation principle of nanocellulose The preparation of nanocellulose mainly relies on dissociating the microstructure of natural cellulose to reduce the cellulose molecular chain from the micron level to the nanometer level, thereby obtaining nanofibers with high specific surface area and high crystallinity. According to different preparation methods, common processes can be divided into mechanical methods, chemical methods, enzymatic methods, and composite methods. two
