Nanocellulose is a new functional material made from nano-treated natural cellulose. It has advantages such as high specific surface area, high strength, and biodegradability. In recent years, it has received widespread attention in the fields of composite materials, energy, medicine, electronics, etc. Among them, the thermal stability of nanocellulose is one of the key parameters that determine whether it can be used in high temperature or thermal processing environments. 1. Thermal stability of nanocellulose Overview Thermal stability of nanocellulose mainly depends on its source, surface chemical modification method and dispersion state. Generally speaking, natural cellulose begins to pyrolyze above 200°C, while nanocellulose after TEMPO oxidation, acid hydrolysis or enzymatic lysis may reduce or increase the pyrolyze temperature, depending on the introduction of surface functional groups and changes in crystal structure. Studies have shown that the thermal decomposition temperature of unmodified nanocellulose in the air is usually at 250.

1. Overview of Nanocellulose Nanocellulose is a new green polymer material obtained by nanoscale dissociation treatment using natural cellulose as raw material. It not only has excellent properties such as light weight, high strength, and large specific surface area, but also has environmentally friendly characteristics such as renewability, biocompatibility and degradability, and has become an important research direction for sustainable high-performance materials. Compared with traditional micro-scale cellulose, nanocellulose has performed better in transparency, mechanical properties, suspension stability, etc., and is widely used in many fields such as high-performance materials, biomedicine, food packaging, electronic devices, etc. Among them, cellulose nanocrystals (CNC) are the most widely studied category and are usually prepared by acid hydrolysis. The process is mature and easy to control, and has become one of the key process routes in laboratory and industrial research. 2. Principle of acid hydrolysis method Natural cellulose consists of highly ordered crystallization regions and disordered

1. Introduction to Nanocellulose Nanocellulose is a nano-scale fiber material obtained by mechanical, chemical or enzymatic treatment of natural cellulose. Its unique nanostructure gives it high strength, high specific surface area and good dispersion, becoming an important boost to the performance improvement in the adhesive field. 2. The mechanism of action of nanocellulose in adhesives enhances structural strength. Nanocellulose has high Young's modulus and tensile strength. After being added to the adhesive system, it can form a fine nanonetwork structure, effectively improving the overall mechanical properties of the adhesive. Improve rheological properties The high specific surface area and surface activity of nanocellulose can adjust the viscosity and fluidity of the adhesive, achieving better construction performance and coating uniformity. Enhance the interface binding force Nanocellulose is rich in hydroxyl groups, which can form hydrogen bonds or chemical bonds with the surface of the substrate, enhance the interface binding force between the adhesive and the attached material, and improve bond strength and durability.

With the popularity of global environmental protection concepts and the growth of demand for biomedical materials, Nanocellulose, as a green and sustainable nanobiomaterial, is leading the wave of innovation in materials science due to its unique biocompatibility and degradability. This article will deeply analyze the two core advantages of nanocellulose and reveal its wide application potential in multiple fields. 1. Nanocellulose biocompatibility: natural friendly, promoting life and health 1.1 Definition and importance of biocompatibility Biocompatibility refers to the ability of materials to maintain a good coexistence state when they come into contact with biological tissues or cells, and does not cause immune rejection, toxicity or inflammatory reactions. For medical materials, food contact materials and other fields, biocompatibility is a basic evaluation indicator. 1.2 Natural advantages of nanocellulose. Natural source, structural stability. Nanocellulose is derived from plant cellulose. It is the richest natural polymer on the earth.

What is bacterial cellulose? Bacterial Cellulose (BC) is a high-purity cellulose produced by specific microorganisms such as Gluconacetobacter xylinus and other acetates under contamination conditions. Compared with traditional plant cellulose, bacterial cellulose does not contain impurities such as lignin and hemicellulose, and the fibers are arranged in order and have higher crystallinity, so they have natural advantages in physical properties and functionality. Principle of the formation of nanoscale three-dimensional network structure One of the core characteristics of bacterial cellulose is its automatically formed nanoscale three-dimensional network structure during growth. The formation of this structure originates from the conversion of carbon sources such as glucose into a single cellulose microfiber filament with a diameter of about 20 to 100 nanometers through extracellular synthesis pathways, and is continuously superimposed and interwoven on the surface of the growth liquid, and finally constructed a highly versatile one.

Nanocellulose: With film-forming and transparency, it leads a new direction for green functional films. What is nanocellulose? Nanocellulose is a nano-scale fiber material prepared by physical, chemical or enzymatic methods using natural cellulose as raw materials. The fiber diameter is generally 5 to 50 nanometers and the length can reach several microns. Compared with traditional cellulose, nanocellulose not only retains green characteristics such as renewable and degradable, but also shows excellent mechanical, optical and processing properties because of its nanostructure, making it a globally recognized new generation of high-performance bio-based material. Where does excellent film-forming and transparency come from? 1. The dense network brought by the nanoscale nanocellulose has an extremely high specific surface area. The fibers are tightly wound by hydrogen bonds, and can be self-assembled into a continuous and dense three-dimensional network in the aqueous phase, making it easy to prepare a uniform membrane layer with flat surfaces and no holes. 2. The light scattering is extremely small and transparent

The diameter is usually 5 to 50 nanometers and the length can reach more than several microns. It not only retains the renewability and degradability of cellulose itself, but also shows high strength, low density and excellent optical properties because of its nanostructure. It is one of the green and sustainable materials that have attracted much attention in the field of new materials in recent years. 2. Core advantages of nanocellulose film-forming and transparency 1. Strong self-assembly capability Nanocellulose can form a dense three-dimensional network structure through hydrogen bonding and physical cross-linking in an aqueous system, making it easy to form a continuous, uniform and dense film on the surface of the substrate. 2. High light transmittance Since the fiber diameter is much smaller than the visible light wavelength, it can effectively reduce light scattering. The prepared nanocellulose film still has
