Supercritical drying is a process used to remove solvents from materials, particularly in the creation of aerogels and other porous materials. It involves the use of supercritical fluids, typically carbon dioxide (CO2), which are substances that are held above their critical temperature and pressure, resulting in properties that are intermediary between gases and liquids. Here's a brief overview of the process: 1. **Preparation**: The material to be dried, such as a gel, is first saturated with a solvent.
