Structure and morphology determine the properties of polymeric materials. This atlas provides, with over 2000 high-quality micrographs a comprehensive overview of the structural/morphological diversity of all classes of plastics. 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 plastics 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.
