The cellulose aerogel market has broad development space and related research is continuing to deepen.

Cellulose aerogel refers to an aerogel product prepared based on cellulose materials. According to different raw materials and production processes, it can be divided into pure cellulose aerogel directly generated from pure cellulose as raw material and cellulose aerogel based on cellulose water. There are two categories of cellulose composite aerogels, which are raw materials modified by adding inorganic materials. Cellulose aerogels have the advantages of high porosity, high specific surface area, biodegradability, chemical stability, reproducibility, easy surface modification, high temperature resistance, etc., following inorganic aerogels and polymer aerogels. The third generation aerogel product developed.

Cellulose airgel raw materials come from a wide range of sources, and the industry has a good foundation for development. Cellulose is the core raw material of cellulose aerogels. It can be extracted not only from wood, cotton, cotton linters, wheat straw, rice straw, bagasse and other plants, but also from wastes such as newspapers and cartons, and Acetobacter xylinum. Extracted from bacterial fermentation.

According to the “2023-2028 Cellulose Airgel Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center It shows that in recent years, the application fields of cellulose aerogels are continuously expanding. In the early days, cellulose aerogels were widely used in aerospace, national defense, precision instruments and other fields due to their excellent thermal insulation effect; as adsorption, degradation capabilities and other excellent properties gradually emerged, the application fields gradually expanded to petrochemical, biological and other fields. Medicine, rail transit, electronic appliances, water treatment, environmental protection and other fields.

As research continues to deepen, a research team from the University of Colorado in the United States has used methods such as colloidal self-assembly and compatibility with roll-to-roll processing to prepare a new type of highly transparent cellulose aerogel, which provides advanced solutions for door and window glass with high transparency and high thermal insulation functions. Technical solutions. In addition, a research team from the University of Science and Technology of China developed a super-elastic cellulose aerogel, and a research team from the Chinese Academy of Forestry developed a lignocellulose aerogel. In the future, cellulose aerogel products are expected to play an important role in building energy conservation, industrial insulation, oil pollution adsorption and other fields, and the market development space is broad.

Industry AnalysisPersonnel said thatCellulose aerogel is one of the new aerogel materials. The production process is relatively complex and the production cost is high. Large-scale commercial mass production has not yet been achieved. However, there are many companies laying out cellulose aerogel research and development tracks. For example, Audemars Piguet and New Materials signed a “Project Development Cooperation Agreement” with the Swiss Federal Institute of Materials abroad to jointly develop a large-scale production process for cellulose aerogels. . In the future, as relevant research institutions and enterprises continue to increase their research and development efforts on cellulose aerogels, its market development space will gradually expand and the industrialization process will continue to accelerate.
