Supercritical carbon dioxide (scCO

2

) as a green solvent has attracted much attention in the academic community and industrial sector. In the last decade

new polymerization techniques related to scCO

2

such as carbon dioxide hybrid mediums and continuous stirred reactor tank

have been developed. Moreover

various functional polymer materials including fluoroplastics

fluoroelastomers

core-shell composites

porous materials

and perfluorosulfonic acid membranes

have been prepared using the technology of supercritical carbon dioxide. The above mentioned recent developments in the area are introduced briefly in this article.
