Subcritical and supercritical carbon dioxide (CO2), as an alternative solvent, is one of the unique fluids playing an important role in the development of environmentally favorable technologies. It acts as not only a good solvent to dissolve many low molecular substances, but also a good plasticizing agent for polymeric materials. Plasticization is the underlying principle in various polymer processing technologies with high-pressure CO2, such as low-temperature molding, polymer foaming, impregnation and surface modification. The purpose of this article is to review recent advances in polymer processing using CO2 fluid.
