Nanocellulose aerogel has not yet achieved commercial mass production, and research and development efforts need to be increased in the future.

Cellulose aerogel refers to aerogel products prepared based on cellulose materials. According to different structures, cellulose aerogels can be divided into three categories: nanocellulose aerogels, regenerated cellulose aerogels, and cellulose derivative aerogels. Nanocellulose aerogel refers to an aerogel product prepared from nanocellulose materials with a diameter of 2-100 nanometers and a length of several hundred nanometers or microns.

Nanocellulose is the key raw material for the production of nanocellulose aerogels, which is mainly prepared from cellulose derived from wood, cotton, sugarcane bagasse and other plant sources. Common wood cellulose has a width of about 0.03 mm and a length of 1-3 mm. The cellulose material needs to be physically ground and purified first, and then degraded through high-pressure homogenization, mechanical ball milling or acid hydrolysis. Finally, Only in this way can the nanoscale cellulose materials required for composites be generated. The nanocellulose aerogel raw material market has the advantages of a wide range of sources and the disadvantage of difficulty in manufacturing. The number of companies that have achieved mass production in the world is still relatively small, and the market supply is insufficient.

According to the “2023-2028 Nanocellulose Airgel Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research CenterIt shows that nanocellulose aerogels have the excellent properties of nanocellulose such as easy modification, high transparency, renewable, degradable, good biocompatibility, strong mechanical stability, etc., as well as the high porosity and high porosity of aerogels. Special properties such as large specific surface area have made it one of the third-generation aerogel products with great development potential. It has broad applications in adsorption, energy storage, electromagnetic interference, biomedicine, aerospace, industrial insulation, building energy conservation and other fields. prospect.

At present, nanocellulose aerogels have become a hot area of ​​research and development by domestic and foreign enterprises and research institutions. For example, the research team of Qingdao University of Science and Technology developed nanocellulose hybrid silica aerogels, which have great application in construction, industry, aviation and other fields. Huge application potential; a research team from the Holy Land University of Ganshung in India has developed nanocellulose aerogels combined with curcumin, which can play an important role in the treatment of chronic wounds. However, due to the difficulty of production technology and insufficient supply of raw materials, nanocellulose aerogels have not yet achieved large-scale commercial mass production. In the future, relevant companies and research institutions need to increase research and development efforts and accelerate the research and development process to realize nanofibers as soon as possible. The industrialization process of plain airgel.

​

Industry AnalysisPersonnel said thatnanocellulose aerogel is one of the segmented products with great development potential in the third-generation aerogel market. It has now become a key material required in high-precision fields and has great application prospects. relatively broad. However, due to limitations in raw materials and technology, nanocellulose aerogels have not yet achieved large-scale commercial mass production. In the future, local companies will need to increase product research and development efforts and strive to occupy the first-mover advantage in the market. There is huge room for industry growth.
