1. Overview of bacterial cellulose Bacterial cellulose (BC) is a natural polymer material synthesized by specific microorganisms during the fermentation process. Compared with traditional plant cellulose, bacterial cellulose does not need to undergo complex chemical decontamination steps during the production process and does not contain lignin and hemicellulose. Therefore, it has higher purity, more stable structure and better biocompatibility. At the microstructural level, bacterial cellulose self-assembles from nanofibers with a diameter of about 20–100 nm to form a three-dimensional network structure. This highly uniform and continuous nanonetwork is the structural basis for its high strength, high water retention, and good film-forming properties. 2. Key performance advantages of bacterial cellulose 1. High purity and biosafety Bacterial cellulose is prepared by biological fermentation. The material itself is highly pure, has good biocompatibility and low irritation, and is used in medical, daily chemical and other applications.

As the demand for green materials and high-performance functional materials continues to grow, nanocellulose (Nanocellulose), as a type of nanoscale material derived from natural cellulose, is gradually becoming an important part of the new generation of functional additions and structural reinforcement materials. It combines the advantages of reproducibility, high performance and environmental friendliness, and shows broad application prospects in multiple industrial fields. 1. Basic structure and type of nanocellulose Nanocellulose is a nanoscale fibrous material obtained by defibrillating natural cellulose by physical, chemical or biological methods. It usually has a high aspect ratio structure with a diameter of nanometer level and a length of micron level or more. Depending on the preparation method and structural characteristics, nanocellulose mainly includes nanocellulose (CNF), nanocrystalline cellulose (CNC), and bacterial cellulose (BC). From a microstructural point of view, nanocellulose retains the highly ordered crystal structure of cellulose molecules, and at the same time

The suspension mechanism of nanocellulose and its engineering application in liquid formulations Nanocellulose (Nanocellulose) is a new type of functional material obtained from natural cellulose through nanotechnology. It is being widely used in the daily chemical, food, pharmaceutical and functional materials industries because of its renewable, safety and environmental protection, high stability and other advantages. Among them, 'strong suspension ability, high transparency, and excellent thixotropy' have become one of the most industrially valuable properties of nanocellulose.

1. Introduction to Nanocellulose Nanocellulose is a nanoscale material derived from natural cellulose and prepared through mechanical, chemical or enzymatic methods. Its diameter is between 5–100 nm, which is much smaller than the wavelength of visible light, making it outstanding in terms of optical performance. As a new green, renewable, and degradable functional material, nanocellulose has attracted great attention in fields such as transparent films, flexible displays, and optical devices due to its high transparency and optical stability. 2. Why does nanocellulose have high light transmittance? The reason why nanocellulose can achieve a high transmittance of 85–95% is essentially due to the following three reasons: 1. The diameter of the fibrils is much smaller than the wavelength of visible light. The wavelength of visible light is 400–700 nm, while the diameter of nanocellulose is only a few nanometers to tens of nanometers, which is much lower than the wavelength of light, so that light is almost not scattered in the material, making it transparent

1. Introduction: Bacterial Cellulose (BC), a nanomaterial 'crafted by microorganisms', is a type of high-purity cellulose directly synthesized by Acetobacter genus (such as Komagataeibacter xylinus) through fermentation. Unlike cellulose derived from plants, BC skips the long and complex lignification process in nature and achieves highly ordered nanofiber assembly from the level of microbial metabolism. It does not contain lignin, hemicellulose and ash impurities, and its fiber diameter is generally 20-100 nm. It is a typical 'natural nanocellulose (NFC)'. Against the background of surging research fields such as sustainable materials, biomedical materials, flexible electronics, and energy storage, BC is becoming an important basic material for multidisciplinary research because of its precisely controllable microstructure, strength, and biocompatibility. 2.

1. What is nanocellulose? Nanocellulose is a nanoscale functional material obtained from natural cellulose after mechanical, chemical or enzymatic treatment. The fiber diameter is usually 5-50 nm. It has natural advantages such as high crystallinity, high aspect ratio, renewable and degradable, and is known as the 'super material in the green era'. Nanocellulose is mainly divided into three categories: CNF (cellulose nanofiber): obtained through mechanical or TEMPO oxidation pretreatment, in the form of filaments. CNC (cellulose nanocrystals): obtained after acid hydrolysis, the structure is highly crystalline. BC (bacterial cellulose): synthesized by bacterial fermentation and has extremely high purity. 2. Core performance advantages 1. Ultra-high mechanical strength and modulus The strength of nanocellulose can reach 1–2 GPa, and the Young’s modulus can reach 100–150 GPa, which is an order of magnitude higher than conventional wood pulp fibers and is comparable to high-strength fibers such as Kevlar.
