Recent developments in materials synthesis and processing using supercritical CO2

The chemical and physical properties of carbon dioxide in the liquid or sup ercritical state differ quite strongly from those of conventional liquid or ganic Solvent,. These differences may be exploited in a wide variety of mat erials applications. Here we describe recent research involving the use of dense carbon dioxide in the areas of porous organic materials, coatings and lithography, metal nanoparticle synthesis, and biomaterials processing.
