中文摘要	the melt viscosity behavior of three-arm and six-arm star polystyrene (sps)/c-60 composites was studied. it was found that the changing trend in the melt viscosity of sps/c-60 composites depended on the molecular weight of the arm chain (m-a) of sps and the content of c-60. when the m(a)of sps was smaller than the critical molecular weight for the entanglement (mc) of polystyrene (ps), the complex viscosity obtained at 0.05 rad s(-1) (eta(0.05)) of sps/c-60 composites with a low content of c-60 was lower than that of pure sps. when the m-a was larger than the m-c of ps, however, the eta(0.05) of the sps/c-60 composites was higher than that of pure sps. these results were contrary to the previous work on the melt viscosity behavior of linear ps (lps)/c-60 composites (a. tuteja et al., macromolecules, 2007, 40, 9427-9434), where the eta* at low shear frequencies of lps/c-60 composites was higher than that of pure lps when the molecular weight (m-w) of lps was smaller than the m-c of ps, and the eta* at low shear frequencies of lps/c-60 was lower than that of pure lps when the m-w of lps was larger than the m-c of ps. the possible mechanism behind the melt viscosity behavior of sps/c-60 composites was discussed. it was expected that the topological structure of sps induced a more heterogeneous dispersion of c-60 in the sps matrix than the dispersion state of c-60 in the lps matrix. when the molecular weight of sps was different, the contact states between sps and c-60 might also be different, which would make c-60 act as a lubricator or barrier, leading to the reduction or increase of the melt viscosity of sps/c-60, respectively.
