abstract = {An extensive characterization of well-defined polystyrene
(PS)-grafted silica nanoparticles is reported. Bare SiO2
particles (diameter 50 nm) were functionalized with a
suitable initiator for the surface-initiated anionic
polymerization of styrene. Both grafted and free PS chains
were characterized and compared by size-exclusion
chromatography (SEC). PS-grafted particles were
characterized by transmission electron microscopy (TEM),
thermogravimetric analysis (TGA), small-angle x-ray
scattering (SAXS), small-angle neutron scattering (SANS),
and dynamic light scattering (DLS). The thickness of the
grafted PS chains was obtained by SANS and DLS and scaled
with M0.6w displaying similar behavior with free PS chains
in the same solvent used, tetrahydrofuran (THF). Grafting
densities obtained from SANS data and TGA were found to be
small, and the thickness of the grafted PS chains determined
by SANS was found to be similar to 2Rg of free PS chains in
THF. Both results are consistent with a “coil-like”
conformation of the grafted PS chains.},
