| 中文摘要 | isotactic polypropylene (ipp) was successfully grafted onto multiwalled carbon nanotubes (mwnts) by direct macroradical addition by sonication in hot xylene with bpo as an initiator. a quantitative determination of the grafting ratio was first realized after the ipp-g-mwnts were extensively purified by repeated hot vacuum filtration and redispersion in xylene at 130 degrees c. it was found that both ipp macromolecular radicals and small-molecular benzoic acid free radicals were grafted onto mwnts. ipp-g-mwnts dispersed more uniformly in ipp than pristine mwnts. the ipp-g-mwnts/ipp composites have much higher elongations at break than the ipp composites filled with pristine mwnts, and the young's modulus and yield strength were also improved to some extent. ipp-g-mwnts also have a stronger nucleation effect on the crystallization of ipp than pristine mwnts. |
