The improvement of strength and durability in polymers has implications relevant to industrial, medical, and household applications. Enhanced by the improved knowledge of the interactions between complex hierarchical structures and functional requirements, Mechanical Properties of Polymers Based on Nanostructure and Morphology focuses on new polyme
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.
Micro- and Nanostructured Multiphase Polymer Blend Systems: Phase Morphology and Interfaces focuses on the formation of phase morphology in polymer blends and copolymers and considers various types of blends including thermosets, thermoplastics, thermoplastic vulcanizates, and structured copolymers. The book carefully debates the processing
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.
Polymer composites are materials in which the matrix polymer isreinforced with organic/inorganic fillers of a definite size andshape, leading to enhanced performance of the resultant composite.These materials find a wide number of applications in such diversefields as geotextiles, building, electronics, medical, packaging,and automobiles. This first systematic reference on the topic emphasizes thecharacteristics and dimension of this reinforcement. The authors are leading researchers in the field from academia,government, industry, as well as private research institutionsacross the globe, and adopt a practical approach here, coveringsuch aspects as the preparation, characterization, properties andtheory of polymer composites. The book begins by discussing the state of the art, new challenges,and opportunities of various polymer composite systems. Interfacialcharacterization of the composites is discussed in detail, as isthe macro- and micromechanics of the composites. Structure-propertyrelationships in various composite systems are explained with thehelp of theoretical models, while processing techniques for variousmacro- to nanocomposite systems and the influence of processingparameters on the properties of the composite are reviewed indetail. The characterization of microstructure, elastic,viscoelastic, static and dynamic mechanical, thermal, tribological,rheological, optical, electrical and barrier properties arehighlighted, as well as their myriad applications. Divided into three volumes: Vol. 1. Macro- and Microcomposites;Vol. 2. Nanocomposites; and Vol. 3. Biocomposites.
Volume B forms one volume of a Handbook about Polymer Nanocomposites. Volume B deals with Carbon nanotube based polymer composites. The preparation, architecture, characterisation, properties and application of polymer nanocomposites are discussed within some 25 chapters. Each chapter has been authored by experts in the respective field.
The study of polymers by electron microscopy (EM) needs special techniques, precautions and preparation methods, including ultramicrotomy. General characteristics of the different techniques of EM, including scanning force microscopy, are given in this hands-on book. The application of these techniques to the study of morphology and properties, particularly micromechanical properties, is described in detail. Examples from all classes of polymers are presented.
Over 30% of commercial polymers are blends or alloys or one kind or another. Nanostructured blends offer the scientist or plastics engineer a new range of possibilities with characteristics including thermodynamic stablility; the potential to improve material transparency, creep and solvent resistance; the potential to simultaneously increase tensile strength and ductility; superior rheological properties; and relatively low cost. Nanostructured Polymer Blends opens up immense structural possibilities via chemical and mechanical modifications that generate novel properties and functions and high-performance characteristics at a low cost. The emerging applications of these new materials cover a wide range of industry sectors, encompassing the coatings and adhesives industry, electronics, energy (photovoltaics), aerospace and medical devices (where polymer blends provide innovations in biocompatible materials). This book explains the science of nanostructure formation and the nature of interphase formations, demystifies the design of nanostructured blends to achieve specific properties, and introduces the applications for this important new class of nanomaterial. All the key topics related to recent advances in blends are covered: IPNs, phase morphologies, composites and nanocomposites, nanostructure formation, the chemistry and structure of additives, etc. Introduces the science and technology of nanostructured polymer blends – and the procedures involved in melt blending and chemical blending to produce new materials with specific performance characteristics Unlocks the potential of nanostructured polymer blends for applications across sectors, including electronics, energy/photovoltaics, aerospace/automotive, and medical devices (biocompatible polymers) Explains the performance benefits in areas including rheological properties, thermodynamic stablility, material transparency, solvent resistance, etc.
This book focuses on the recent trends in micro- and nano-structured polymer systems, particularly natural polymers, biopolymers, biomaterials, and their composites, blends, and IPNs.
