AI Technical Summary
Traditional aerogel preparation methods are costly, using large amounts of organic solvents and supercritical drying technology, resulting in low production efficiency and easy decomposition of the product at high temperatures. Furthermore, hydrophobic aerogels have poor interaction with other materials, limiting their applications.
By employing direct suspension dispersion technology and modified sol-gel synthesis technology, the use of organic solvents and surfactants is reduced. Low-cost, high-purity aerogel powder with low thermal conductivity is prepared through hydrolysis, condensation and suspension dispersion steps. Atmospheric pressure drying technology is used to replace supercritical drying.
It enables low-cost and high-efficiency production of high-purity aerogel powder, improves its stability in high-temperature environments and its interaction with other materials, and expands its application temperature range and compatibility.
