Supercritical Drying Experimental Device

Supercritical Drying Experimental Device

The drying process of the gel is crucial for the preparation of aerogels. Traditional methods lead to coarsening of the base particles, a significant decrease in specific surface area, and a large reduction in porosity. However, supercritical fluid drying technology, due to the supercritical fluid's combined gas-liquid properties, absence of surface tension, and additional pressure, can prevent gel structure collapse and shrinkage, maintaining the network framework structure. This results in ultrafine aerogels with high specific surface area, uniform particle size distribution, and large pore volume. Aerogels, as porous nanomaterials with high specific surface area and low bulk density, have broad application prospects in aerospace, catalysis, environmental protection, and other fields due to their unique nanostructure. Their common preparation method, the sol-gel process, includes three stages: sol preparation, gel preparation, and gel drying.
