Due to its high specific surface area characteristics, aerogels have broad application prospects in aerospace, catalysis, environmental protection, and medical applications. Aerogel preparation and drying technology has become an emerging field in chemical engineering research.
Since the supercritical fluid has both gas and liquid properties, there is no gas-liquid interface, and therefore there is no surface tension. At this time, there is no additional pressure generated by the surface tension in the capillary pores of the gel. Therefore, the use of the gel under the conditions of supercritical fluids does not cause collapse of the gel structure caused by the additional pressure, avoids the shrinkage of the gel during the drying process, and maintains the gel network framework structure. An ultra-fine aerogel with high specific surface area, uniform particle size distribution and large pore volume.
