Foaming with Supercritical Fluids provides a comprehensive description of the use of supercritical fluids as blowing agents in polymer foaming. To this aim, the fundamental issues on which the proper design and control of such a process are rooted are discussed in detail, with specific attention devoted to (1) the theoretical and experimental aspects of sorption thermodynamics of a blowing agent within a polymer, (2) the effect of the absorbed blowing agent on the thermal, interfacial and rheological properties of the expanding matter, and (3) the phase separation of the gaseous phase and of the related bubble nucleation and growth phenomena. Several foaming technologies based on the use of supercritical blowing agents are then described, addressing the main issues in the light of the underlying chemical-physical phenomena. Offers strong fundamentals on polymer properties important on foaming Outlines the use of Supercritical Fluids for foaming Covers several steps leading to the foam formation from a modelling as well as theoretical point of view, including foam formation of the polymer/gas solution to the setting of the final foam Discusses the several processing technologies and applications

Advanced Nanotechnology and Application of Supercritical Fluids

Globalization and industrialization involve a number of reactions, products, extractions, and separations that require the use of organic solvents. These solvents are responsible for a number of ecological concerns, including atmospheric and land toxicity. Conventional organic solvents are regarded as volatile organic compounds; some are even limited due to their

Polymer processing using supercritical fluids

The traditional methods for polymer processing use environmentally hazardous volatile organic solvents and chlorofluorocarbons. Due to the increase of hazardous solvent emission and generation of aqueous waste streams, there is an obvious need of finding new and cleaner methods for the processing of polymers. Supercritical carbon dioxide (scCO2) has attracted

Construction of Novel Tissue Engineering Scaffolds Using Supercritical Fluid Gas Foaming

Three dimensional scaffolds were created from a biodegradable polymer (polylactide) and the mineral silica utilising supercritical fluid (SCF) gas foaming. The effect of silica on the scaffold pore architecture was investigated through X-ray computed microtomography (microCT); the scaffolds were shown to be up to 60% porous with pore diameters in the
