Nanocellulose is an important green nanomaterial, widely used in high-performance composite materials, medical materials, and environmentally friendly packaging. This paper will focus on introducing the detailed process of preparing nanocellulose by sulfuric acid hydrolysis, and analyze the advantages and disadvantages of the method and the principle of preparing nanocellulose by monosulfate hydrolysis. Sulfuric acid hydrolysis is a common method for extracting nanocellulose from natural cellulose (such as wood pulp, cotton, sugar cane bagasse, etc.). This method uses concentrated sulfuric acid hydrolysis cellulose to decompose the amorphous region in the cellulose, and finally obtains nanocellulose prepared with high crystallinity. The nanocellulose prepared with high crystallinity has good mechanical properties, biodegradability and high specific surface area. It is suitable for a variety of application scenarios.

The high specific surface area characteristics of nanocellulose and its technical application. Introduction Among many new green nanomaterials, nanocellulose (Nanocellulose) has attracted much attention due to its renewable, biodegradable, non-toxic and environmentally friendly advantages. It is also worth mentioning that high specific surface area, as one of its core properties, has greatly expanded the application of nanocellulose in the fields of interface modification of functional material adsorption materials. What is a high specific surface area? Specific Surface Area refers to the total surface area of ​​a unit mass material. The unit is usually m²/g.
