Book Description
Structure and morphology determine the properties of polymeric materials. This atlas provides, with well over 2000 high-quality micrographs, a comprehensive overview of the structural/morphological diversity of all classes of polymers. All microscopic techniques from light microscopy through scanning and transmission electron microscopy to atomic force microscopy are covered. Another focus is on the changes in polymer morphology occurring under mechanical stress, i.e. the deformation and fracture structures. The extensive visual material will help professionals in research and application fields to determine structure-property correlations of polymeric materials and also improve training and teaching in universities. The organized structure of the book based on polymer groups--together with helpful tables to guide the reader easily to the appropriate images according to polymer type, morphological detail, deformation structure, or other structural detail--make this a user-friendly reference for all interested in structure and properties of polymeric materials.

Book Description
The aim of the present edited book is to furnish scientific information about manufacturing, properties, and application of clay and carbon based polymer nanocomposites. It can be used as handbook for undergraduate and post graduate courses (for example material science and engineering, polymer science and engineering, rubber technology, manufacturing engineering, etc.) as well as as reference book for research fellows and professionals. Polymer nanocomposites have received outstanding importance in the present decade because of their broad range of high-performance applications in various areas of engineering and technology due to their special material properties. A great interest is dedicated to nanofiller based polymeric materials, which exhibit excellent enhancement in macroscopic material properties (mechanical, thermal, dynamic mechanical, electrical and many more) at very low filler contents and can therefore be used for the development of next-generation composite materials.

Book Description
Comprehensive knowledge on the preparation, characterization, and applications of polymer nanocomposites Chemical Physics of Polymer Nanocomposites examines the state of the art in preparation, processing, characterizing, and applying a wide range of polymer nanocomposites, elucidating nanofiller/polymer interactions, nanofiller dispersion, distribution, filler-filler interactions, and interface properties, with a particular focus on the rheology of this important class of materials. The dependence of the rheological properties on the preparation techniques is discussed in detail, complemented by an overview of the processing approaches using conventional and micro injection molding, extrusion, compression molding, film blowing, pultrusion, and resin transfer molding. The book covers the latest understanding and accomplishments on polymer composites and presents the huge variety of this materials class. Practice-oriented with industry relevance, it also reviews preparation, characterization, morphology, properties, applications, sustainability, and recyclability. The topics covered in Chemical Physics of Polymer Nanocomposites include: Classification of nano fillers, nano-objects, nanomaterials, and polymer nanocomposites based on chemical nature and identity, and synthesis and characterization of nanoparticles General manufacturing methods and processes, including melt and shear mixing manufacturing of polymer nanocomposites 1D nano fillers and polymer nanocomposites, including polymer nanocomposites based on graphite nanoplatelets (GNP) and amphiphilic graphene platelets Polymer nanocomposites based on nano chitin, starch, and lignin, gold nanowires, titanium dioxide, and graphene and graphene oxide Chemical Physics of Polymer Nanocomposites is an essential resource for materials scientists, polymer chemists, chemical engineers, and engineering scientists in industry.

Book Description
The combination of functional polymers with inorganic nanostructured compounds has become a major area of research and technological development owing to the remarkable properties and multifunctionalities deriving from their nano and hybrid structures. In this context, polyhedral oligomeric silsesquioxanes (POSSs) have increasing importance and a dominant position with respect to the reinforcement of polymeric materials. Although POSSs were first described in 1946 by Scott, these materials, however, have not immediately been successful if we consider that, starting from 1946 and up to 1995, we find in the literature 85 manuscripts regarding POSSs; which means that less than two papers per year were published over 50 years. Since 1995, we observe an exponential growth of scientific manuscripts concerning POSSs. It is changing from an annual average of 20 manuscripts for the period 1995–2000 to an annual average of about 400 manuscripts, with an increase of 2800%. The introduction of POSSs inorganic nanostructures into polymers gives rise to polymer nanostructured materials (PNMs) with interesting mechanical and physical properties, thus representing a radical alternative to the traditional filled polymers or polymer compositions.

Book Description
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 Description
The present book focuses on the preparation, properties, characterisation and applications of polymer nanocomposites. The various manufacturing techniques, analysis of morphology, filler dispersion, and interfacial interactions have been described are detail. In the case of polymer nanocomposites, filler dispersion, intercalation/exfoliation, orientation and filler-matrix interaction are the main parameters that determine the physical, thermal, transport, mechanical and rheological properties of the nanocomposites. In this book the ultimate properties of the nanocomposites have been correlated with the key parameters of filler dispersion and filler-matrix interaction. The use of various sophisticated instrument techniques for the characterisation of these nanocomposites are also reviewed.
