摘要: Chain behavior has been determined in polymer nanocomposites (PNCs) comprised of well-dispersed 12 nm diameter silica nanoparticles (NPs) poly(methyl methacrylate) (PMMA) matrices by Small-Angle Neutron Scattering (SANS) measurements under the Zero Average Contrast (ZAC) condition. In particular, we directly characterize bound layer surrounding NPs, revealing profile. The SANS spectra high-q region also show no significant change bulk radius gyration on addition NPs. We thus suggest that conformation PNCs should generally be using high q data.
