[Abstract] Supercritical fluids (SCFs) represent the state of matter that exists whenever pressure of fluids reach above their critical point. This state holds a special diffusivity similar to gases with combined dissolving power comparable to liquids. SCFs provide an effective reaction environment for the synthesis of novel types of polymer materials and their modification into composites, blends, useful nanostructures ,nanocomposites and nanohybrids. Tuning supercritical conditions allows for precise regulation of filler size, shape, aspect ratios, infusion, deposition, dispersion, and exfoliation. Carbon dioxide offers as the source of the most useful supercritical fluid, so called supercritical carbon dioxide. The primary objectives of the talk will pertain to the salient characteristics of SCFs and their applications in the production of technologically valuable polymer materials used to make durable structures, sensors, energy storage, and items of biomedical importance.[1-6]. Final thoughts on simplicity, diversity, and the marketplace of supercritical fluid technology in material science and engineering will be presented.
