Samenvatting

With a focus on structure–property relationships, this book describes how polymer morphology affects properties and how scientists can modify them. The book covers structure development, theory, simulation, and processing; and discusses a broad range of techniques and methods.

Provides an up–to–date, comprehensive introduction to the principles and practices of polymer morphology
Illustrates major structure types, such as semicrystalline morphology, surface–induced polymer crystallization, phase separation, self–assembly, deformation, and surface topography
Covers a variety of polymers, such as homopolymers, block copolymers, polymer thin films, polymer blends, and polymer nanocomposites
Discusses a broad range of advanced and novel techniques and methods, like x–ray diffraction, thermal analysis, and electron microscopy and their applications in the morphology of polymer materials
