摘要: Supercritical fluids have a unique and valuable potential for the enhanced processing of many mate- rials. This review describes research in applications supercritical to polymer processing. The ability carbon dioxide swell plasticize polymers is crucial impregnation, extraction, modification polymeric materials. plasticization also reduces viscosity facilitates due lower shear stresses. Spectroscopy plays an important role probing these interactions at molecular level follow situ processes CO 2 -induced crystallization poly- mers. Opportunities exist improving polymeric-based materials ranging from textile food biomaterials. implications between drying, dyeing, foaming extrusion are discussed with outlook further opportunities this related areas
