Available in PDF, EPUB and Kindle. Book excerpt: Foaming with Supercritical Fluids, Volume Nine 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 this process are rooted are discussed in detail, with specific attention devoted to the theoretical and experimental aspects of sorption thermodynamics of a blowing agent within a polymer, the effect of the absorbed blowing agent on the thermal, interfacial and rheological properties of the expanding matter, and 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 theoretical points-of-view, including foam formation of the polymer/gas solution to the setting of the final foam Discusses the several processing technologies and applications

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The cell density (bubbles/cm3 of polymer) and bubble size of the intercalated polystyrene nano-clay composite foams are reviewed as a function of concentration and temperature. 5% intercalated polystyrene nano-clay composites were mixed with pure polystyrene and diluted to prepare 3%, 1%, 0.3%, 0.1% and 0.03% intercalated polystyrene nano-clay composites by mechanical blending with a screw rotation speed of 150 RPM and a temperature of 200° C. Once these nano-clay composites were prepared, they were foamed with supercritical carbon dioxide as the foaming agent in a batch foaming process at the temperatures of 80° C, 100° C and 120° C. Different concentrations of these intercalated polystyrene nano-clay composite foams were compared with the pure polystyrene foam at 120° C. Also, 3% intercalated polystyrene nano-clay composite foam at 80° C, 100° C and 120° C were compared. The number of bubbles/cm3 of polymer increased and the bubble size decreased with the increase in concentration of the intercalated polystyrene nano-clay composite foams, other conditions being constant, although the pure polymer was found to have the maximum cell density and the least bubble size. The cell density decreased and the bubble size increased with the increase in temperature at which the intercalated polystyrene nano-clay composite was foamed. Only three samples were used in examining the effect of temperature and there was inconsistency in the results obtained. Hence, a convincing conclusion for the relation between the temperature at which the polymer nanocomposite was foamed and the cell density as well as the bubble size was not obtained.

Book excerpt: Advances in nanotechnology have boosted the development of more efficient materials, with emerging sectors (electronics, energy, aerospace, etc.) demanding novel materials to fulfill the complex technical requirements of their products. This is the case of polymeric foams, which may display good structural properties alongside functional characteristics through a complex composition and (micro)structure in which a gas phase is combined with rigid ones, mainly based on nanoparticles, dispersed throughout the polymer matrix. In recent years, there has been an important impulse in the development of nanocomposite foams, extending the concept of nanocomposites to the field of cellular materials. This, alongside developments in new advanced foaming technologies which have allowed the generation of foams with micro, sub-micro, and even nanocellular structures, has extended the applications of more traditional foams in terms of weight reduction, damping, and thermal and/or acoustic insulation to novel possibilities, such as electromagnetic interference (EMI) shielding. This Special Issue, which consists of a total of 22 articles, including one review article written by research groups of experts in the field, considers recent research on novel polymer-based foams in all their aspects: design, composition, processing and fabrication, microstructure, characterization and analysis, applications and service behavior, recycling and reuse, etc.

Available in PDF, EPUB and Kindle. Book excerpt: SCFs are currently the subjects of intense research and commercial interest. Applications such as the RESS (rapid expansion of supercritical fluid solutions) process are part of standard industrial practice. In view of their ever-growing importance in the polymer industry there is a need to fully comprehend how supercritical fluids interrelate with polymeric materials to realise the potential that can be gained from their use. The authors review the basic principles of SCFs and their application within the polymer industry: characteristics and properties, extraction of unwanted residual products, polymerisation solvents, and polymer impregnation. Processing applications such as plasticisation, foaming and blending are also considered. There is discussion of the potential within the polymer recycling industry for use of SCFs as cleaning agents or within supercritical oxidation processes. Around 400 references with abstracts from recent global literature accompany this review, sourced from the Polymer Library, to facilitate further reading. A subject index and a company index are included.

Available in PDF, EPUB and Kindle. Book excerpt: Polylactide Foams: Fundamentals, Manufacturing, and Applications provides an introduction to the fundamental science behind plastic foams, polylactic acid) and polylactide foaming, giving designers tactics to replace traditional resins with sustainable and biodegradable materials. The book then delves deeper into the technology behind PLA foaming, such as PLA/gas mixture characteristics, solubility, interfacial tension behaviors and crystallization kinetics of various types of PLA and their compounds. The foaming behaviors and mechanisms of various types of PLA and PLA compounds are extensively analyzed and discussed through different manufacturing technologies, namely extrusion foaming, foam injection molding and bead foaming. Interest in Poly(lactic acid) and PLA foams is extremely high – particularly as a potential replacement for styrenic resins – and the price of PLA resin is lower than ever before. This biopolymer has significant potential to improve the sustainability of the plastics industry. Polylactide Foams have a range of potential applications, such as in construction, packaging, insulation, biomedical scaffolds, and others. However, processing and performance of PLA are not at the same level as other non-biodegradable resins. Introduces the concepts behind foaming, poly(lactic acid) and PLA foaming Supports further research and development in PLA foams by covering the state-of-the-art in different manufacturing and processing methods Provides practical guidance for materials scientists and engineers in industry looking to replace traditional polymer resins with a sustainable, biodegradable alternative

Available in PDF, EPUB and Kindle. Book excerpt: The vast majority of plastic products are made from petroleum-based synthetic polymers that do not degrade in a landfill or in a compost-like environment. Therefore, the disposal of these products poses a serious environmental problem. An environmentally-conscious alternative is to design/synthesize polymers that are biodegradable. Biodegradable polymers for industrial applications introduces the subject in part one by outlining the classification and development of biodegradable polymers with individual chapters on polyhydroxyalkanoates, polyesteramides and thermoplastic starch biodegradable polymers and others. The second part explores the materials available for the production of biodegradable polymers. Polymers derived from sugars, natural fibres, renewable forest resources, poly(lactic acid) and protein-nanoparticle composites will be looked at in detail in this section. Part three looks at the properties and mechanisms of degradation, prefacing the subject with a chapter on current standards. The final part explores opportunities for industrial applications, with chapters on packing, agriculture and biodegradable polycaprolactone foams in supercritical carbon dioxide. Biodegradable polymers for industrial applications explores the fundamental concepts concerning the development of biodegradable polymers, degradable polymers from sustainable sources, degradation and properties and industrial applications. It is an authoritative book that will be invaluable for academics, researchers and policy makers in the industry.
