Polymer Processing with Supercritical Fluids
Supercritical fluids have a unique and valuable potential for the enhanced processing of many materials. This review describes research in the applications of supercritical fluids to polymer processing. The ability of supercritical carbon dioxide to swell and plasticize polymers is crucial to the impregnation, extraction, and modification of polymeric materials. This plasticization also reduces...

متن کاملElectrochemistry in supercritical fluids
A wide range of supercritical fluids (SCFs) have been studied as solvents for electrochemistry with carbon dioxide and hydrofluorocarbons (HFCs) being the most extensively studied. Recent advances have shown that it is possible to get well-resolved voltammetry in SCFs by suitable choice of the conditions and the electrolyte. In this review, we discuss the voltammetry obtained in these systems, ...
متن کاملApplication of Supercritical Fluids
Many advantages of supercritical fluids come from their interesting or unusual properties which liquid solvents and gas carriers do not possess. Such properties and possible applications of supercritical fluids are reviewed. As these fluids never condense at above their critical temperatures, supercritical drying is useful to prepare dry-gel. The solubility and other important parameters as a s...
متن کاملSupercritical Fluids as Processing Media for Nanostructured Devices
Supercritical fluids including carbon dioxide offer a combination of properties that are uniquely suited for device fabrication at the nanoscale. Liquid-like densities, favorable transport properties, and the absence of surface tension enable solution-based processing in an environment that behaves much like a gas.These characteristics provide a means for extending “top-down” processing methods...
