| 抄録: | Influences of polypropylene (PP) grafted to SiO_2 nanoparticles (7 nm) were studied on the crystallization behavior and the mechanical properties of PP/SiO_2 nanocomposites. PP for the matrix and grafting was synthesized in order to have an identical primary structure, aiming at their co-crystallization and resulting reinforcement of filler-matrix interfaces. The grafted PP chains improved the dispersion of SiO_2, and notably accelerated nucleation in crystallization. It was plausible that the grafted chains whose one chain end was pinned to SiO_2 became nuclei of the crystallization (co-crystallization between the matrix and grafted chains), thus directly bridging between the matrix and SiO_2 nanoparticles. The Young’s modulus and tensile strength were most improved by the grafted PP chains at low filler contents such as 2.3 wt%, whose origin was attributed to effective load transfer to SiO_2 through the co-crystallization-mediated bridging. |
