Supercritical fluids are used also as an alternative green process to conventional ones to obtain nano- and micro-polymeric particles and even drug-polymer systems with special properties that go towards new future formulations. However, different supercritical fluids processes are recommended depending on the polymer features such as solubility in SCCO2 and final applications. 

A supercritical fluid can be defined as a substance above its critical temperature and pressure. At this condition, the fluid has unique properties, where it does not condense or evaporate to form a
