Small-angle neutron scattering (SANS) is a sensitive technique that is able to probe the structure of polymer-grafted nanoparticles and free polymer chains. Here, we combine SANS measurements with self-consistent field theory (SCFT) calculations to study the structure of deuterated poly(methyl methacrylate) (dPMMA) nanocomposites containing PMMA-grafted Fe3O4 nanospheres, with a specific emphas...
