Combined small-angle neutron and x-ray scattering studies of polymers

摘要

Over the past two decades, small-angle neutron scattering (SANS), using cold neutrons (4-20 (angstrom)), has proven to be an important tool for the evaluation of polymer chain conformation. Due to a fortuitous combination of several factors (penetrating power, deuteration, solvent choice), SANS has developed into a very powerful tool for the study of polymers. This article focuses on the information provided by SANS and demonstrates how it has complemented and expanded upon the data available from other scattering techniques (e.g., SAXS). Applications to homogenous polymer mixtures, phase-separated polymer blends, and carbon-filled polymers are discussed. 34 refs, 18 figs, 2 tabs. (DLC)
