Scattering from Polymers: Characterization by X-rays, Neutrons, and LightThis book reflects the recent progress made in the field of scattering in polymers. A wide range of scattering studies on different polymer systems, including block copolymers, semicrystalline polymers, complex fluids, multicomponent systems, polymeric surfaces, and polymer processing are included, as well as new experimental techniques and theoretical treatments. This volume provides a comprehensive reference for those researchers who need to know how scattering techniques can be used to tackle different polymer problems, and is ideal for graduate polymer scientists studying scattering techniques. |
