This book was released on 2013-01-30 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results in this dissertation set the ground to answer a fundamental question in data-driven polymer material science: "Why don't prepared composites show less fatigue than the pure plastics?" A simultaneous analysis of mechanical testing and small angle X-Ray scattering from the DESY source in Hamburg has been applied to approach this question, which is also central to the European research project "Nanotough", and the results are clearly presented in this book. The evolution of the materials structure is visualized and quantitatively analyzed from exhaustive sequences of scattering images. Three different classes of polymer composites are presented as typical and illustrative examples. The obtained results illustrate that the interactions of their components can cause unpredictable structural effects, ultimaltely leading to a weakening of the material, where a reinforcement was expected.

Download or read book Nanostructured Polymer Blends written by Robert A. Shanks and published by Elsevier Inc. Chapters. This book was released on 2013-11-28 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many nanostructured materials have been and are being prepared with increasing control over molecular configurations, conformations, and supramolecular assembly. These nanomaterials place an increasing challenge for characterization techniques to confirm the proposed structure and morphology. Several techniques are widely available, with increasing degrees of sophistication. Ideal techniques are those where the natural scale of the technique, such as radiation wavelength, matches that of the size scale of features in the material. In the case of nanostructured polymer blends the features are dispersed polymer phases, filler particles, and interphases. Immediately electron microscopies and X-ray techniques are apparent. Adaptions of these and related techniques extend their capabilities for the nano range. In addition to experimental observations, methods for quantifying the images or data are needed for comparison between materials and modeling via theoretical equations, which in the limit may become molecular modeling. As needs arise instruments have been improved in detection, resolution, accuracy, and precision. Development of any nanomaterial requires support from a suite of increasingly capable instrumentation. This review concentrates on techniques that directly probe nanostructures with mention of related techniques that apply to any dimension scale, though provide important secondary data.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been a great deal of research on the subject of nanostructured materials. Structure across a range of length scales has been of particular interest. Theoretical modeling of nanostructured formation in polymer blends has gained considerable momentum due to the increased interest in nanostructures, such as nanoparticles, nanotubes, nanopores, and so on. Polymers show universal behavior on long length and time scales. Usually, the size of an ideal polymer is calculated from the freely jointed polymer chain model. The solubility and interaction parameters in nanostructured polymer blends are reviewed. Several computer simulation models for predicting mechanical, electrical, and thermal properties of semicrystalline polymer and nanostructured polymer blends are discussed. Modeling of polymer in solution and the morphological control of nanostructured blends are also reviewed. Further development of nanostructured polymer blends depends on the fundamental understanding of their hierarchical structure and behavior, which requires multiscale modeling and simulation to provide various lengths and time scales. Atomistic-based simulation such as molecular dynamics, Monte Carlo, and molecular mechanics are addressed for the multiscale modeling of nanostructured polymer blends for material design. A mathematical model based on the Cahn–Hilliard nonlinear theory of phase separation is also discussed.

Download or read book Nanostructured Polymer Blends written by Juan Rodríguez-Hernández and published by Elsevier Inc. Chapters. This book was released on 2013-11-28 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of polymer blends constitutes an interesting alternative to obtaining micro- and nanostructured surfaces. The cost is reasonable and it is free from time-consuming procedures. Blending of polymers can yield materials with unprecedented properties that cannot be provided otherwise by using a single polymer. The free surface topography of polymer blend films, often related to phase domain structure, is critical to the applications. Two main aspects need to be considered in the preparation of multistructured blends: the interfaces involved and the morphology to be obtained. The control of these two aspects depends further on materials-related parameters involving the composition of the blend, the interfacial tension or viscosity ratio, and the processing conditions related to the temperature, time, or intensity of mixing, among others. Both domain structure and topography of the blend films have garnered increasing interest over the past decade. This chapter describes the nanomicrostructures formed at the polymer surface from polymer blends. Despite the crucial role that surfaces play in the final application of the material, up to now most of the studies concerning polymer blends have been related to the control of the mechanical properties (toughness, stiffness, thermal expansion, etc.), their barrier properties, or the electrical conductivity. This chapter focuses on the analysis of the structured polymer surfaces and thin films, giving an overview of the role of these structures on the final application. The principles of phase separation and the resulting structures formed are briefly discussed, followed by a wide overview of the possibilities of producing stimuli-responsive interfaces by introducing, among other things, pH- or temperature-responsive polymers within the blend. Finally, we look at how using particular preparation conditions and/or self-assembly of block copolymers, the formation of films and surfaces with hierarchical order length-scales can be induced. We also examine the main areas in which multiscale-ordered interfaces obtained from polymer blends have been applied.

Available in PDF, EPUB and Kindle. Book excerpt: Great progress has been made in the science and technology of polymer-based nanomaterials over the last decade. Nanostructured polymer systems have attracted much scientific and applied research interest. The last two decades have witnessed significant advances in polymer science and technology generally, but more so for polymer blends. The idea of blending two (or more) polymers, especially immiscible blends, has come with a lot of challenges. Achieving this has brought to the fore the art and science (and engineering) of compatibilization. During the last few decades, the addition of nanoparticles, nanowires, nanotubes, and so on has advanced even further the creation of blends, alloys, and composites with different polymers. In making these blends, intermediaries such as compatibilizers, coupling agents, and other additives are often employed to bring about blends that are satisfactory for the purposes they are intended to serve. Nanostructured polymer blends formation has strongly improved the properties and structural integrities of polymer blends, by employing compatibilization as a tool to achieve such properties and structural integrities of polymer blends. Reinforcing compatibilized polymer blends with nanosize additives has further strengthened the properties and integrities of polymer blends, alloys, and composites.

Download or read book Micro and Nanostructured Epoxy Rubber Blends written by Sabu Thomas and published by John Wiley & Sons. This book was released on 2014-11-03 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epoxy resins are polymers which are extensively used as coating materials due to their outstanding mechanical properties and good handling characteristics. A disadvantage results from their high cross-link density: they are brittle and have very low resistance to crack growth and propagation. This necessitates the toughening of the epoxy matrix without impairing its good thermomechanical properties. The final properties of the polymer depend on their structure. The book focuses on the microstructural aspects in the modification of epoxy resins with low molecular weight liquid rubbers, one of the prime toughening agents commonly employed. The book follows thoroughly the reactions of elastomer-modified epoxy resins from their liquid stage to the network formation. It gives an in-depth view into the cure reaction, phase separation and the simultaneous development of the morphology. Chapters on ageing, failure analysis and life cycle analysis round out the book.

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.
