The SiO2 aerogel composite developed and produced by GAWEE is made by drying the noncrystal silicagel and its substrate blanket with the supercritical CO2 fluid. The process can reduce the intrinsic high brittleness of the aerogel effectively, and strengthen the structure of valence bond between the aerogel and its substrate. The aerogel can be widely used in construction and petrochemical fields.
