With the deep integration of materials science and optical engineering, nanocellulose has become the core substrate for building high-performance structural color materials by virtue of its natural nanoscale, excellent self-assembly properties and green sustainable attributes, bringing revolutionary breakthroughs to the fields of anti-counterfeiting, optical films, flexible displays and other fields. As a natural polymer material derived from biomass such as wood, cotton, and straw, nanocellulose not only inherits the environmental protection genes of biomass, but also solves the industry pain points of traditional chemical dyes that are easy to fade, highly polluted, and difficult to control with its unique microstructure. 1. Nanocellulose: Natural green nanomaterial Nanocellulose is a nanoscale cellulose material prepared from natural biomass through physical, chemical or biological methods. It is mainly divided into two categories: cellulose nanocrystals (CNC) and cellulose nanofibers (CNF). Its core characteristics lay the foundation for structural color construction: Nanoscale and high aspect ratio: CNC diameter is about 5-50

In the wave of global green and low-carbon transformation and new material technology innovation, a new type of material derived from nature, high performance and environmentally friendly, nanocellulose, is gradually entering the public eye and becoming the 'green key' to promote the upgrading of many industries. As the most abundant natural polymer material in nature, cellulose, after being modified at the nanoscale, has excellent properties that far exceed those of traditional materials. It shows broad application prospects in many fields such as lithium batteries, packaging, biomedicine, and papermaking, and also injects new momentum into the high-quality development of enterprises. 1. Understanding nanocellulose: The 'nanomiracle' gifted by nature, nanocellulose (Nanocellulose), is a linear material with a diameter of several nanometers to tens of nanometers, a length of tens of nanometers to several micrometers, and a certain aspect ratio. It is made from natural cellulose as raw material and processed through physical, chemical or biological methods [1]. Its English name is nanocellulose, as

Currently, the world is advocating green development. As a natural material synthesized by microbial fermentation, bacterial cellulose (BC) has become a core material for innovation in many fields due to its advantages of being natural, efficient, and degradable. Nanjing Tianlu Nanotechnology Co., Ltd. is deeply involved in the field of nanomaterials and specializes in the research and development, production and sales of nanocellulose products such as bacterial cellulose. This is also an important direction for us to lay out green new materials and help industrial upgrading. What is bacterial cellulose? Bacterial cellulose is natural cellulose produced by fermentation of specific microorganisms. It has similar composition to plant cellulose, but has better performance. It has high purity, no impurities, and a fine nanoscale network structure. It is not only tough in texture, but also naturally degrades and harmless to the human body. The production process is low-energy consumption and environmentally friendly, and does not require cutting down trees, which is in line with the concept of green development. Multi-field applications of bacterial cellulose With its unique advantages, bacterial cellulose has achieved industrial application in many fields. Nanjing Tianlu Nano Technology
