In the field of outdoor building materials, traditional wood is easy to rot and crack, ordinary plastic plates have poor weather resistance, and metal plates are easy to rust and consume high energy. The industry is in urgent need of new materials that are environmentally friendly, durable, and high-strength. Nanocellulose outdoor panels (NCT panels for short) use nanocellulose extracted from plant fibers as the core raw material. With the advantages of nanoscale structure and composite modification technology, they are perfectly adapted to complex outdoor working conditions and have become the first choice for upgrading the outdoor panel market, promoting the transformation of the building materials industry into a low-carbon, long-term, and safe direction. 1. Nanocellulose: Nanocellulose, the core hard-core material of outdoor boards, is a nanoscale fiber material extracted from natural plant fibers such as wood, straw, and bamboo through mechanical dissociation, enzymatic hydrolysis, and other processes. It has a diameter of only 1-100 nanometers, but has core properties that far exceed those of traditional materials. Ultra-high strength: The tensile strength of nanocellulose is more than 5 times that of steel, and the Young's modulus is close to that of carbon fiber, providing stability for outdoor boards.

As counterfeiting methods continue to escalate and traditional anti-counterfeiting technologies are easily cracked, the market has an increasingly urgent need for anti-counterfeiting solutions that are highly secure, difficult to counterfeit, and green and environmentally friendly. Nanocellulose (with cellulose nanocrystalline CNC and nanofibrillated cellulose CNF as the core) is a green nanomaterial derived from natural biomass. With its unique chiral self-assembly structure, dynamic iridescent optical properties, and nanometer-level non-replicable precision, nanocellulose is becoming the core material in the field of high-end anti-counterfeiting, providing new solutions for 'physical-level anti-counterfeiting and green applications' for documents, currency, luxury goods, high-end packaging and other scenarios. Nanjing Tianlu Nanotechnology Co., Ltd. is deeply involved in the field of nanocellulose, specializing in the research and development, production and application promotion of nanocellulose. It has large-scale preparation and stable modification technology, and is committed to promoting the industrialization of green nanomaterials in high-end anti-counterfeiting, functional coatings, green packaging and other fields. 1.
