Main body of CO₂ supercritical drying equipment
The drying process of gels is an important step. Traditional drying methods have the following adverse effects on the preparation of aerogels: the base particles of the material become coarser, the specific surface area significantly decreases, and the porosity is greatly reduced. The supercritical fluid drying technology developed in recent years does not produce these adverse effects.
Since supercritical fluids possess both gas and liquid properties and have no gas-liquid interface, there is no surface tension present. Therefore, there is no additional pressure caused by surface tension in the capillary pores of the gel. Drying gels under supercritical fluid conditions does not cause the collapse of the gel structure due to additional pressure, avoids shrinkage during drying, maintains the gel network framework, and produces ultrafine aerogels with high specific surface area, uniform particle size distribution, and large pore volume.
Aerogels are porous nanomaterials with high specific surface area and low bulk density. Due to their unique nanostructure, aerogels have broad application prospects in aerospace, catalysis, environmental protection, and other fields. Their preparation technology has become an emerging area of research in chemical engineering. The sol-gel method is a commonly used technique for preparing aerogels, which includes three processes: sol preparation, gel preparation, and gel drying.
