There are many types of polymer-based aerogels, and energy saving and high-end development are important development directions.

Aerogel is a nanoscale porous solid material. There are many types of aerogels, which can be divided into inorganic aerogels, organic aerogels, hybrid aerogels and composite aerogels. Organic aerogels are divided into aldehyde series, urea derivatives, polymer bases, etc. Polymer-based aerogels are organic compounds with a porous network structure formed by combining polymer molecules with colloidal particles through hydrogen bonds or van der Waals forces.

There are many types of polymer-based aerogels, including polyurethane aerogels, polyimide aerogels, polyurea aerogels, etc. In recent years, as research continues to deepen, more and more new polymer-based aerogels Adhesives have emerged, such as syndiotactic polystyrene polyvinylidene fluoride aerogels, polybenzoxazine aerogels, polychiro composite aerogels, etc. At present, polymer-based aerogels have developed into the third generation, namely natural polymer-based aerogels, which are degradable and renewable.

my country’s aerogel market started late, and there is still a gap compared with the European and American markets in terms of material research and development, production, application and market development. However, in recent years, driven by national policy support and preparation technology progress, my country’s aerogel market has developed strongly and the industrial scale has continued to expand. In 2021, the aerogel production capacity will be around 200,000 square meters. Production companies include China National Chemical and Zhonghe Technology , Guangdong Alison, Pan-Asia Microtransmission, etc. Domestic aerogels are mainly carbon aerogels, polymer-based organic aerogels, and silica aerogels.

According to the “2022-2027 China Polymer-based Airgel Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center 》 shows that polymer-based aerogels have the characteristics of flexible design and adjustable performance, and have good application prospects in aerospace, flexible electronics, energy systems, industrial insulation, construction materials, automobiles, environmental protection, petrochemicals and other fields. In the context of the country’s vigorous advocacy of energy conservation, the demand for polymer-based airgel applications will continue to be released, and industry development will shift towards high-end, low-carbon, and energy-saving directions.

The type of polymer affects the performance of aerogels. For example, polyimide aerogels have the advantages of high thermal stability, good chemical stability, and high strength. However, they also have shortcomings such as poor liquid permeability, low mechanical properties, and poor flexibility. The earth limits its market application. In order to meet the market demand for high-quality materials, improving the performance of polymer-based aerogels has become one of the hot topics among researchers.

Industry analysts said that there are many types of polymer-based aerogels, and as research continues to deepen, polymer-based aerogels The variety is constantly expanding. Polymer-based aerogels have a wide range of applications. Under the dual-carbon background, the market demand for energy-saving, low-carbon, and high-quality aerogel materials will continue to grow. Relevant companies should increase research on the performance of polymer-based aerogels to promote the industry Develop in the direction of high-end and low-carbon development.
