1. Supercritical Fluid

   Linked via "Supercritical Drying"

   SCFs are utilized as porogens or reaction media in polymer science. The high diffusivity of SCFs allows monomers and cross-linking agents to penetrate polymer matrices rapidly.
   In the synthesis of porous materials, such as aerogels, the process of Supercritical Drying is paramount. If a wet gel is dried conventionally (below $\text{P}_c$), the liquid/vapor interface generates immense [capillary pressures](/entries/capillary-pressur…
