                      investigation of mixtures of poly(ethylene oxide)
                      (PEO)/polyhedral oligomeric silsesquioxane (POSS) hybrids, a
                      popular nanofiller, addressing the conformation of the
                      model-grafted nanoparticles as well as their influence on
                      the linear polymer matrix in which they are embedded. The
                      nanofiller has a well-defined graft arm length and is
                      monomolecular. Because of the identical chemical nature of
                      the grafted arm and matrix chains, it can be considered as
                      an ideal athermal mixture. We have introduced a random phase
                      approximation approach with general application
                      possibilities for other grafted nanofillers, combining the
                      star-like and particle-like characteristics of the POSS
                      nanofiller. The size of the nanofiller remained unaffected
                      and Gaussian upon mixing with linear chains of various
                      lengths, and no aggregation of the nanofiller was observed.
                      This turns the POSS-based nanocomposite into an interesting
                      model compound. The mixtures of PEO chains with the
                      octafunctional PEO–POSS nanofiller were found to resemble
                      those of a micellar system whereas within experimental
                      uncertainty the radius of gyration of the embedding matrix
                      remained basically unaltered despite some tendency toward
                      shrinking.},
