Polymers and Neutron ScatteringNeutron scattering has become a widely applied technique for studying problems in polymer science and technology. This is the first book written specifically for non-specialists that introduces the theoretical models and experimental techniques needed to understand results obtained from neutron scattering. In attempting to present a readable text that requires little expert knowledge, the authors have produced a practical volume that fills the gap between the often technical, pedagogic research articles that have characterized the literature and the almost entire absence of information available to the polymer scientist who desires a firmer grasp of the advantages offered by neutron scattering in materials research. Researchers and graduate students interested in polymers and neutron scattering will find this book useful and informative. |
