Book Synopsis Polyurethane Elastomers by : Cristina Prisacariu
Download or read book Polyurethane Elastomers written by Cristina Prisacariu and published by Springer Science & Business Media. This book was released on 2011-07-03 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive account of the physical / mechanical behaviour of polyurethanes (PU ́s) elastomers, films and blends of variable crystallinity. Aspects covered include the elasticity and inelasticity of amorphous to crystalline PUs, in relation to their sensitivity to chemical and physical structure. A study is made of how aspects of the constitutive responses of PUs vary with composition: the polyaddition procedure, the hard segment, soft segment and chain extender (diols and diamines) are varied systematically in a large number of systems of model and novel crosslinked andthermoplastic PUs. Results will be related to: microstructural changes, on the basis of evidence from x-ray scattering (SAXS and WAXS), and also dynamic mechanical analyses (DMA), differential scanning calorimetry (DSC) and IR dichroism. Inelastic effects will be investigated also by including quantitative correlations between the magnitude of the Mullins effect and the fractional energy dissipation by hysteresis under cyclic straining, giving common relations approached by all the materials studied. A major structural feature explored is the relationship between the nature of the hard segment (crystallising or not) and that of the soft segments. Crystallinity has been sometimes observed in the commercial PUs hard phase but this is usually limited to only a few percent for most hard segment structures when solidified from the melt. One particular diisocyanate, 4,4’-dibenzyl diisocyanate (DBDI) that, in the presence of suitable chain extenders ( diols or diamines), gives rise to significant degrees of crystallinity [i-iii] and this is included in the present work. Understanding the reaction pathways involved, in resolving the subtle morphological evolution at the nanometre level, and capturing mathematically the complex, large-deformation nonlinear viscoelastic mechanical behaviour are assumed to bring new important insights in the world basic research in polyurethanes and towards applied industrial research in this area.

Book Synopsis Thermoplastic Elastomers by : Chapal Kumar Das
Download or read book Thermoplastic Elastomers written by Chapal Kumar Das and published by BoD – Books on Demand. This book was released on 2015-11-26 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermoplastic elastomers (TPEs), commonly known as thermoplastic rubbers, are a category of copolymers having thermoplastic and elastomeric characteristics. A TPE is a rubbery material with properties very close to those of conventional vulcanized rubber at normal conditions. It can be processed in a molten state even at elevated temperatures. TPEs show advantages typical of both rubbery materials and plastic materials. TPEs are a class of polymers bridging between the service properties of elastomers and the processing properties of thermoplastics. Nowadays, the best use of thermoplastics is in the field of biomedical applications, starting from artificial skin to many of the artificial human body parts. Apart from these, thermoplastic elastomers are being used for drug encapsulation purposes, and since they are biocompatible in many cases, their scope of applications has been broadened in the biotechnological field as well. The present book highlights many biological and biomedical applications of TPEs from which the broader area readers will benefit.

Book Synopsis Polymer/POSS Nanocomposites and Hybrid Materials by : Susheel Kalia
Download or read book Polymer/POSS Nanocomposites and Hybrid Materials written by Susheel Kalia and published by Springer. This book was released on 2018-11-27 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of polymer nanocomposites and hybrid materials with polyhedral oligomeric silsesquioxanes (POSS). Among inorganic nanoparticles, functionalized POSS are unique nano-building blocks that can be used to create a wide variety of hybrid and composite materials, where precise control of nanostructures and properties is required. This book describes the influence of incorporation of POSS moieties into (organic) polymer matrices on the mechanical, thermal and flammability behavior of composites and hybrid organic-inorganic materials. Importantly, POSS-containing materials can be bio-functionalized by linking e.g. peptides and growth factors through appropriate surface modification in order to enhance the haemo-compatibility of cardiovascular devices made of these materials. This volume includes descriptions of synthesis routes of POSS and POSS-containing polymeric materials (e.g. based on polyolefines, epoxy resins and polyurethanes), presentation of POSS’ role as flame retardants and as biocompatible linker, as well as the depiction of decomposition and ageing processes.

This book was released on 1984 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Segmented poly(ether-b-urethanes) have been synthesized with 2000 MW polypropylene oxide coupled with diisocyanates and diol type chain extenders. The diisocyanates used were symmetric rigid 4,4'-diphenylmethane diisocyanate (MDI), linear aliphatic hexamethylene diisocyanate (HDI) and unsymmetric rigid toluene-2,4-diisocyanate (TDI). The chain extenders were symmetric N, N'-bis(2-hydroxyethyl) terephthalamide (BT) and N, N'-bis(2-hydroxyethyl)-hydroquinone (BH) unsymmetric N, N'-bis(2-hydroxyethyl)isophthalamide, and linear aliphatic butanediol. Hard segment contents ranged from 20 to 40 wt %. The thermal behavior of these materials is consistent with phase separation into separate hard and soft domains.
