      abstract     = {We previously reported that grafted polystyrene (PS) chains
                      on silica nanoparticles at a low grafting density show
                      similar conformations to free PS chains in the same solvent,
                      THF (diameter ˜50 nm, Colloid.poly.Sci. (2013), 291, 9,
                      2087–2099). As an extension of our previous study we
                      choose an organic nanoparticle (deuterated polystyrene, dPS)
                      instead of inorganic nanoparticle to see the impact of the
                      substrate material on chain conformation. Additionally, a
                      wider range of molecular weights were prepared to
                      investigate the conformation feature of grafted PS chains
                      more in detail. Small angle neutron scattering (SANS)
                      experiments were performed to characterize PS grafted dPS
                      particles in good solvent condition, with deuterated toluene
                      and deuterated THF as solvent. To get insight into the
                      conformation of the grafted PS layer we apply a scaling law
                      describing the dimension of free PS polymer in good solvent
                      condition to the obtained thickness of the grafted PS layer.
                      We find an overall agreement with the scaling law where the
                      thickness of the grafted PS layer is slightly larger than
                      2Rg of the free polymer chains in the respective solvent
                      giving hint for semi dilute polymer brush (SDPB) situation.},
