Synthesis and Processing of Porous Polymers Using Supercritical Carbon Dioxide (original) (raw)

The synthesis and processing of porous polymers have been significantly advanced using supercritical carbon dioxide (scCO2) as a solvent. This review outlines the advantages of scCO2, such as its non-toxicity and ability to fine-tune polymer properties by varying density, which enhances control over porosity in macroporous polymers. The application of scCO2 is highlighted through its ability to create polymer beads and monoliths with adjustable pore sizes and surface areas, providing a cleaner and more efficient alternative to traditional solvent-intensive methods.
