——The 'invisible growth engine' in the green materials track 1. Industry background: Nanocellulose enters a high-speed growth cycle Against the background of the 'dual carbon goals' and the continuous advancement of the global sustainable development strategy, nanocellulose (Nanocellulose) is accelerating from laboratory research materials to the industrial application stage. As a natural polymer material that is widely sourced, renewable and degradable, nanocellulose is becoming an important growth point in the field of new materials. According to industry research data, the global nanocellulose market will maintain a compound annual growth rate of more than 20% in the next ten years, and the market size is expected to expand several times. At the same time, demand in composite materials, green packaging, functional coatings and other subdivisions has grown rapidly, further promoting the commercialization of nanocellulose. 2. Capital and industrial trends: Why is nanocellulose rising rapidly? 1. Green materials have become the core investment direction. Driven by the ESG investment concept, the production

1. What is bacterial cellulose? (Basic Science) Bacterial Cellulose (BC) is a natural polymer material produced by microbial fermentation. Compared with traditional plant-derived cellulose, bacterial cellulose has higher purity and a more uniform nanoscale structure. Its typical performance parameters are as follows: Fiber diameter: 20–100 nm Crystallinity: ≥80% Moisture content: up to more than 100 times its own mass Biocompatibility: excellent, non-toxic and non-irritating Since it does not contain lignin and hemicellulose impurities, bacterial cellulose has natural advantages in the field of medical materials. 2. Why have medical dressings become the core application direction? Currently, the field of wound care is upgrading from 'basic coverage' to 'functional repair', and traditional dressings are gradually unable to meet clinical needs. The limitations of traditional dressings include insufficient moisturizing, easy drying and scabbing, and delayed healing of adhesion wounds.

1. What is nanocellulose suspension agent? Nanocellulose (Nanocellulose) is a type of bio-based nanomaterial derived from natural cellulose, mainly including cellulose nanofibrils (CNF), cellulose nanocrystals (CNC) and bacterial cellulose (BC). Among them, CNF is widely used as a new type of nanocellulose suspending agent due to its high aspect ratio and three-dimensional network structure, which shows excellent structural support ability in suspension systems. Compared with traditional thickeners, nanocellulose can not only increase the viscosity of the system, but more importantly, it can achieve stable suspension of particles by building a microscopic network structure, thereby fundamentally solving the problems of settlement and stratification. 2. The mechanism of action of nanocellulose in suspension systems. The core role of nanocellulose in suspension systems is not to simply thicken, but to improve stability through structural regulation. Its mechanism of action is mainly reflected in the following aspects. First, nano
