Processing of polymer nanomaterials in supercritical fluids: bright commercial avenues, entrepreneurial opportunities, and only success

Supercritical fluids (SCFs) present the transient state of liquefiable gases and polar liquids above their critical point wherein the phases separating boundaries are unified into a single phase called SCFs. This state demonstrates unique diffusivity like gases combined with liquid like density. Applications of SCFs as an alternative media in food processing , chromatography, energy production and drug development was recognized till beginning of 19^th century, has now well accepted in processing of nanomaterials . The most preferred SCFs are the supercritical carbon dioxide (SCC) and supercritical water (SCW).SCFs offers a series of unique opportunities synthesis of nanomaterials, development of nanostruuctured polymer blends_, functional nanostructures and polymer nanocomposites. Size, shape and aspect ratios, infusion, deposition, dispersion of nano fillers are well controlled through tuning of physical variables of SCFs. Present keynote shall address the salient features of SCC and SCW in nanoparticle fabrication, synthesis and processing of nanocomposites, nanohybrids and functional nanostructures for antimicrobial, biomedical, anticorrosive, nano-electronic, structural, and energy storage, applications. Concluding remarks will be presented on simplicity, diversity, economics, market potential, entrepreneurship avenues and commercial viability of SCFs assisted processing of nanomaterials.
