| Abstract: | Supercritical fluid impregnation is a new and developing technology. Recently there has been a great deal of interest in using supercritical fluid as a solvent and/or swelling agent to aid in modifying polymer substrate, preparing some medical materials and special functional polymer composite. The study and applications of this technology were reviewed. Involved study is the competition theory of different component in ternary system during the impregnation process. Mentioned applications include modification of polymer materials, preparation of slow-released materials and polymer blends, etc. Future development and outlook of the technology was also addressed. |
